Improve your business performance Optimize installation size, Reduce harmonic distortion to avoid the premature ageing of equipment and destruction of sensitive components.

3 Our solutions. Reactive energy management In electrical networks, reactive energy results in increased line currents for a given active energy transmitted to loads. The main consequences are: Need for oversizing of transmission and distribution networks by utilities, Increased voltage drops and sags along the distribution lines, Additional power losses. This results in increased electricity bills for industrial customers because of: Penalties applied by most utilities on reactive energy, Increased overall kva demand, Increased energy consumption within the installations. Reactive energy management aims to optimize your electrical installation by reducing energy consumption, and to improve power availability. Total CO 2 emissions are also reduced.

4 Improve electrical networks and reduce energy costs Power Factor Correction Every electric machine needs active power (kw) and reactive power to operate. The power rating of the installation in kva is the combination of both: (kva)² = (kw)² + ². The Power Factor has been defined as the ratio of active power (kw) to apparent power (kva). Power Factor = (kw) / (kva). The objective of Reactive Energy management is improvement of Power Factor, or Power Factor Correction. This is typically achieved by producing reactive energy close to the consuming loads, through connection of capacitor banks to the network. II

12 Power Factor Correction guideline Why reactive energy management? Principle of reactive energy management + Due to this higher supplied current, the circulation of reactive energy in distribution networks results in: > Overload of transformers > Higher temperature rise in power cables > Additional losses > Large voltage drops > Higher energy consumption and cost > Less distributed active power. DE90087.eps In this representation, the Power Factor (P/S) is equal to cosj. DE90071_r.eps All AC electrical networks consume two types of power: active power (kw) and reactive power : The active power P (in kw) is the real power transmitted to loads such as motors, lamps, heaters, computers, etc. The electrical active power is transformed into mechanical power, heat or light. The reactive power Q (in kvar) is used only to power the magnetic circuits of machines, motors and transformers. The apparent power S (in kva) is the vector combination of active and reactive power. The circulation of reactive power in the electrical network has major technical and economic consequences. For the same active power P, a higher reactive power means a higher apparent power, and thus a higher current must be supplied. The circulation of active power over time results in active energy (in kwh). The circulation of reactive power over time results in reactive energy (kvarh). In an electrical circuit, the reactive energy is supplied in addition to the active energy. Power generation Active energy Reactive energy Transmission network Reactive energy supplied and billed by the energy provider. Active energy Reactive energy Motor DE90088.eps Q Q c For these reasons, there is a great advantage in generating reactive energy at the load level in order to prevent the unnecessary circulation of current in the network. This is what is known as power factor correction. This is obtained by the connection of capacitors, which produce reactive energy in opposition to the energy absorbed by loads such as motors. The result is a reduced apparent power, and an improved power factor P/S as illustrated in the diagram opposite. The power generation and transmission networks are partially relieved, reducing power losses and making additional transmission capacity available. DE90071_r.eps Power generation Active energy Transmission network Active energy Reactive energy Motor The reactive power is supplied by capacitors. No billing of reactive power by the energy supplier. Capacitors 4

13 Why reactive energy management? + Benefits of reactive energy management Optimized management of reactive energy brings economic and technical advantages. Savings on the electricity bill > Eliminating penalties on reactive energy and decreasing kva demand. > Reducing power losses generated in the transformers and conductors of the installation. Example: Loss reduction in a 630 kva transformer PW = 6,500 W with an initial Power Factor = 0.7. With power factor correction, we obtain a final Power Factor = The losses become: 3,316 W, i.e. a reduction of 49 %. Increasing available power A high power factor optimizes an electrical installation by allowing better use of the components. The power available at the secondary of a MV/LV transformer can therefore be increased by fitting power factor correction equipment on the low voltage side. The table opposite shows the increased available power at the transformer output through improvement of the Power Factor from 0.7 to 1. Power factor Increased available power % % % % % % Reducing installation size Installing power factor correction equipment allows conductor cross-section to be reduced, since less current is absorbed by the compensated installation for the same active power. The opposite table shows the multiplying factor for the conductor cross-section with different power factor values. Power factor Cable crosssection multiplying factor Reducing voltage drops in the installation Installing capacitors allows voltage drops to be reduced upstream of the point where the power factor correction device is connected. This prevents overloading of the network and reduces harmonics, so that you will not have to overrate your installation. 5

14 Power Factor Correction guideline Method for determining compensation The selection of Power Factor Correction equipment can follow a 4-step process: Calculation of the required reactive energy. Selection of the compensation mode: - Central, for the complete installation - By sector - For individual loads, such as large motors. Selection of the compensation type: - Fixed, by connection of a fixed-value capacitor bank; - Automatic, by connection of a different number of steps, allowing adjustment of the reactive energy to the required value; - Dynamic, for compensation of highly fluctuating loads. Allowance for operating conditions and harmonics. Step 1: Calculation of the required reactive power DE90091.eps The objective is to determine the required reactive power Q c to be installed, in order to improve the power factor cos φ and reduce the apparent power S. For φ < φ, we obtain: cos φ > cos φ and tan φ < tan φ. This is illustrated in the diagram opposite. Qc can be determined from the formula Qc = P. (tan φ - tan φ ), which is deduced from the diagram. Q c = power of the capacitor bank in kvar. P = active power of the load in kw. tan φ = tangent of phase shift angle before compensation. tan φ = tangent of phase shift angle after compensation. The parameters φ and tan φ can be obtained from billing data, or from direct measurement in the installation. The following table can be used for direct determination. Before compensation Reactive power to be installed per kw of load, in order to get the required cos j or tan j tan j cos j tan j cos j Example: consider a 1000 kw motor with cos j = 0.8 (tan j = 0.75). In order to obtain cos j = 0.95, it is necessary to install a capacitor bank with a reactive power equal to k x P, i.e.: Qc = 0.42 x 1000 = 420 kvar. 6

15 Method for determining compensation Step 2: Selection of the compensation mode Supply Bus Transformer Circuit breaker The location of low-voltage capacitors in an installation constitutes the mode of compensation, which may be central (one location for the entire installation), by sector (section-by-section), at load level, or some combination of the latter two. In principle, the ideal compensation is applied at a point of consumption and at the level required at any moment in time. In practice, technical and economic factors govern the choice. IC CC GC GC IC IC IC The location for connection of capacitor banks in the electrical network is determined by: th e overall objective (avoid penalties on reactive energy relieve transformer or cables, avoid voltage drops and sags) the operating mode (stable or fluctuating loads) the foreseeable influence of capacitors on the network characteristics the installation cost. M M M M CC : Central Compensation GC : Group Compensation IC : Individual Compensation M : Motor Load Central compensation The capacitor bank is connected at the head of the installation to be compensated in order to provide reactive energy for the whole installation. This configuration is convenient for a stable and continuous load factor. Group compensation (by sector) The capacitor bank is connected at the head of the feeders supplying one particular sector to be compensated. This configuration is convenient for a large installation, with workshops having different load factors. Compensation of individual loads The capacitor bank is connected right at the inductive load terminals (especially large motors). This configuration is very appropriate when the load power is significant compared to the subscribed power. This is the ideal technical configuration, as the reactive energy is produced exactly where it is needed, and adjusted to the demand. 7

16 Power Factor Correction guideline Method for determining compensation Step 3: Selection of the compensation type Different types of compensation should be adopted depending on the performance requirements and complexity of control: Fixed, by connection of a fixed-value capacitor bank Automatic, by connection of a different number of steps, allowing adjustment of the reactive energy to the required value Dynamic, for compensation of highly fluctuating loads. Fixed compensation This arrangement uses one or more capacitor(s) to provide a constant level of compensation. Control may be: Manual: by circuit-breaker or load-break switch Semi-automatic: by contactor Direct connection to an appliance and switched with it. These capacitors are installed: At the terminals of inductive loads (mainly motors) At busbars supplying numerous small motors and inductive appliances for which individual compensation would be too costly In cases where the load factor is reasonably constant. Automatic compensation This kind of compensation provides automatic control and adapts the quantity of reactive power to the variations of the installation in order to maintain the targeted cos j. The equipment is installed at points in an installation where the active-power and/or reactive-power variations are relatively large, for example: on the busbars of a main distribution switchboard on the terminals of a heavily-loaded feeder cable. Where the kvar rating of the capacitors is less than or equal to 15 % of the power supply transformer rating, a fixed value of compensation is appropriate. Above the 15 % level, it is advisable to install an automatically-controlled capacitor bank. Control is usually provided by an electronic device (Power Factor Controller) which monitors the actual power factor and orders the connection or disconnection of capacitors in order to obtain the targeted power factor. The reactive energy is thus controlled by steps. In addition, the Power Factor Controller provides information on the network characteristics (voltage amplitude and distortion, power factor, actual active and reactive power ) and equipment status. Alarm signals are transmitted in case of malfunction. Connection is usually provided by contactors. For compensation of highly fluctuating loads, fast and highly repetitive connection of capacitors is necessary, and static switches must be used. Dynamic compensation This kind of compensation is required when fluctuating loads are present, and voltage fluctuations have to be prevented. The principle of dynamic compensation is to associate a fixed capacitor bank and an electronic var compensator, providing either leading or lagging reactive currents. The result is continuously varying fast compensation, perfectly suitable for loads such as lifts, crushers, spot welding, etc. 8

17 Method for determining compensation + To know more about the influence of harmonics in electrical installations, see appendix page 69 Step 4: Allowing for operating conditions and harmonics Capacitors should be selected depending on the working conditions expected during their lifetime. Allowing for operating conditions The operating conditions have a great influence on the life expectancy of capacitors. The following parameters should be taken into account: Ambient Temperature ( C) Expected over-current, related to voltage disturbances, including maximum sustained overvoltage Maximum number of switching operations/year Required life expectancy. Allowing for harmonics Depending on the magnitude of harmonics in the network, different configurations should be adopted. Standard capacitors: when no significant non-linear loads are present. Oversized capacitors: when a few non-linear loads are present. The rated current of capacitors must be increased in order to cope with the circulation of harmonic currents. Harmonic rated capacitors used with detuned reactors. Applicable when a significant number of non-linear loads are present. Reactors are necessary in order to limit the circulation of harmonic currents and avoid resonance. Tuned filters: when non-linear loads are predominant, requesting harmonic mitigation. A special design is generally necessary, based on on-site measurements and computer simulations of the network. Capacitor selection Different ranges with different levels of ruggedness are proposed: "SDuty": Standard duty capacitors for standard operating conditions, and when no significant non-linear loads are present. "HDuty": Heavy duty capacitors for difficult operating conditions, particularly voltage disturbances, or when a few non-linear loads are present. The rated current of capacitors must be increased in order to cope with the circulation of harmonic currents. "Energy": Specially designed capacitors, for harsh operating conditions, particularly high temperature. Capacitors with detuned reactors: applicable when a significant number of non-linear loads are present. Before After 9

18 Power Factor Correction guideline Low Voltage capacitors with detuned reactors Reactors should be associated with capacitor banks for Power Factor Correction in systems with significant non-linear loads, generating harmonics. Capacitors and reactors are configured in a series resonant circuit, tuned so that the series resonant frequency is below the lowest harmonic frequency present in the system. For this reason, this configuration is usually called Detuned Capacitor Bank, and the reactors are referred to as Detuned Reactors. The use of detuned reactors thus prevents harmonic resonance problems, avoids the risk of overloading the capacitors and helps reduce voltage harmonic distortion in the network. The tuning frequency can be expressed by the relative impedance of the reactor (in %), or by the tuning order, or directly in Hz. The most common values of relative impedance are 5.7, 7 and 14 % (14 % is used with high level of 3rd harmonic voltages). Relative impedance (%) Tuning order Tuning 0Hz (Hz) Tuning 60Hz (Hz) The selection of the tuning frequency of the reactor capacitor depends on several factors: Presence of zero-sequence harmonics (3, 9, ) Need for reduction of the harmonic distortion level Optimization of the capacitor and reactor components Frequency of ripple control system if any. To prevent disturbances of the remote control installation, the tuning frequency should be selected at a lower value than the ripple control frequency. In a detuned filter application, the voltage across the capacitors is higher than the system s rated voltage. In that case, capacitors should be designed to withstand higher voltages. Depending on the selected tuning frequency, part of the harmonic currents is absorbed by the detuned capacitor bank. In that case, capacitors should be designed to withstand higher currents, combining fundamental and harmonic currents. Effective reactive energy In the pages relating to detuned capacitor banks (Harmonic HDuty and Harmonic Energy), the reactive energy given in the tables is the resulting reactive energy provided by the combination of capacitors and reactors. Capacitor rated voltage Capacitors have been specially designed to operate in detuned bank configurations. Parameters such as the rated voltage, over-voltage and over-current capabilities have been improved, compared to standard configuration. 10

19 Rated voltage and current According to IEC standard, the rated voltage (U N ) of a capacitor is defined as the continuously admissible operating voltage. The rated current (I N ) of a capacitor is the current flowing through the capacitor when the rated voltage (U N ) is applied at its terminals, supposing a purely sinusoidal voltage and the exact value of reactive power generated. Capacitor units shall be suitable for continuous operation at an r.m.s. current of (1.3 x I N ). In order to accept system voltage fluctuations, capacitors are designed to sustain over-voltages of limited duration. For compliance to the standard, capacitors are for example requested to sustain over-voltages equal to 1.1 times U N, 8 h per 24 h. VarplusCan and VarplusBox capacitors have been designed and tested extensively to operate safely on industrial networks. The design margin allows operation on networks including voltage fluctuations and common disturbances. Capacitors can be selected with their rated voltage corresponding to the network voltage. For different levels of expected disturbances, different technologies are proposed, with larger design margin for capacitors adapted to the most stringent working conditions (HDuty & Energy). VarplusCan and VarplusBox capacitors when used along with Detuned Reactors have to be selected with a rated voltage higher than network service voltage (U s ). In detuned filter applications, the voltage across the capacitor is higher than the network service voltage (U s ). The recommended rated voltage of capacitors to be used in detuned filter applications with respect to different network service voltage (U s ) and relative impedance is given in the table below. These values ensure a safe operation in the most stringent operating conditions. Less conservative values may be adopted, but a case by case analysis is necessary.

WARNING: the life expectancy will be reduced if capacitors are used in maximum working conditions. Since the harmonics are caused by non-linear loads, an indicator for the magnitude of harmonics is the ratio of the total power of non-linear loads to the power supply transformer rating. This ratio is denoted N LL, and is also known as G h /S n : N LL = Total power of non-linear loads (G h ) / Installed transformer rating (S n ). Example: Power supply transformer rating: S n = 630 kva Total power of non-linear loads: G h = 150 kva N LL = (150/630) x 100 = 24 % It is recommended to use Detuned Reactors with Harmonic Rated Capacitors (higher rated voltage than the network service voltage - see the Harmonic Application Tables) for N LL > 20 % and up to 50 %. Note: there is a high risk in selecting the capacitors based only on N LL as the harmonics in grid may cause current amplification and capacitors along with other devices may fail.
