3 Benefits of harmonic mitigation Harmonic mitigation provides several benefits that could be translated into financial savings for the investor and for the user. It will contribute to improve competitiveness of companies in different ways: Up to % apex and Opex reduction commonly achievable, Improved business performance: downtime significantly reduced, increased equipment lifetime, up to % for single phase machines, up to 8% for three phase machines and up to % for transformers. Reduce capital expenditures Saving on apex is the permanent concern of the investor. Harmonic management provides the opportunity for significant savings ; especially on the cost of equipment. Harmonic mitigation reduces the r.m.s. value of the current and so reduces the size of busbars and cables, and the rating of circuit-breakers and contactors. Reduce operating expenses Opex will be impacted in different ways: Harmonic mitigation generally contributes to reduced power losses in transformers, cables, switchgear Harmonic mitigation allows reducing the subscribed power to the energy supplier. This saving depends on the energy supplier. In most of the cases, savings could be up to % of the electricity bill. Improve electricity availability and business performance Increase reliability and service life. Reduce risks of outage. Increase productivity & quality. Extended equipment lifetime. PE9 Harmonics basic and their effects in the electrical systems Harmonics are a growing concern in the management of electrical systems today. Designers are requested to pay more and more attention to energy savings and improved electricity availability. In this context, the topic of Harmonics is often discussed but there is still a need for more explanation, in order to dissipate confusion and misinterpretation. Power electronic devices have become abundant today due to their capabilities for process control and energy saving benefits. However, they also bring drawbacks to electrical distribution systems: harmonics. The presence of harmonics in electrical systems means that current and voltage are distorted and deviate from sinusoïdal waveforms. Harmonics: origin, effects and consequences Harmonic currents are caused by non-linear loads connected to the distribution system. A load is said to be non-linear when the current it draws does not have the same waveform as the supply voltage. The flow of harmonic currents through system impedances in turn creates voltage harmonics, which distort the supply voltage. Equipment consisting of power electronics circuits are typical non-linear loads. Such loads are increasingly frequent in all industrial, commercial, and residential installations and their percentage in overall electrical consumption is growing steadily. Examples include: Industrial equipment (welders, induction furnaces, battery chargers, D power supplies), Variable Speed Drives for A or D motors, Uninterruptible Power Supplies, Office equipment (s, printers, servers, etc.), Household appliances (TV sets, microwave ovens, fluorescent lighting, light dimmers). Harmonic currents increase the r.m.s. current in the different circuits and deteriorate the supply voltage quality. They stress the electrical network and potentially damage equipment. They may disrupt normal operation of devices and increase operating costs. Symptoms of problematic harmonic levels include overheating of transformers, motors and cables, thermal tripping of protective devices, and logic faults of digital devices. In addition, the life span of many devices can be reduced by elevated operating temperature. Instantaneous effects Harmonics can disrupt controllers used in electronic systems and can adversely affect thyristor switching due to displacement of the zero-crossing of the voltage wave Harmonics can cause vibrations and audible noise in electrical machines (motors, transformers, reactors) Harmonics also reduce available system capacity Long-term effects apacitor heating and degradation (capacitance loss) Heating due to additional losses in transformers Heating of busbars, cables and equipment Thermal damage to induction motors and generators

Provide voltage support on weak grids Avoid voltage fluctuations responsible for flicker and disturbance of sensitive equipment. Improve Power Quality In all these situations, the best result is obtained with fast and continuous reactive energy compensation. Renewable energy generators such as wind turbines, solar panels and small hydro generators are requested by the Utilities to supply reactive energy. The objective is to provide voltage support at the point of connection and reduce the effect of a weak grid. Equipment such as welders, induction furnaces, lifts, crushers operate with rapid and frequent load variations. This results in rapid changes of reactive power requirements. Since the circulation of reactive power in the distribution networks is responsible for voltage drops along the lines, the consequence is the occurrence of fast and large voltage fluctuations at the user s level. This will produce light flicker and cause disturbances of sensitive equipment.

We propose solutions which maximize the savings when balanced with the cost of the harmonic mitigation equipment to get a reasonable Return On Investment (ROI). Schneider Electric can propose different ranges of active filters: SineWave, AccuSine Power orrection System (S), and AccuSine Engineered Solution (ES), which cover a large extent of customer needs. Their main characteristics are summarized below. Schneider Electric solutions: the right choice for each need

5 Active Filter operating principle Active harmonic filters today are designed with two types of control schemes. Discrete logic uses Fast Fourier Transforms (FFT), or other digital means, to calculate the amplitudes and phase angle of each harmonic order. The power devices are directed to produce a current of equal amplitude but opposite phase angle for specific harmonic orders. This limits the response to specific harmonic orders and may require up to two or more cycles (> milliseconds) before responding. SineWave and AccuSine ES employ this logic. The other control scheme (as used by AccuSine S) is called Full Spectrum ancellation. This control scheme doesn t perform FFT. The control algorithms are analog. The controller acquires the current sample from the current transformer, removes the fundamental frequency component and starts injecting the correction within several hundred microseconds. In this manner, all non-fundamental noise is removed for the electrical source. This noise may contain non-integer frequencies, also known as inter-harmonics. Sinewave and AccuSine active filters are also designed to inject reactive current at fundamental frequency to provide power factor correction and, in some cases, compensate for rapid load fluctuations to provide voltage support.
