4 1 ABSTRACT Renewable Energy sources are usually to be looked upon as Distributed Energy Resources (DER). They have to be integrated into a local energy network; the Microgrid. An inverter (DC/AC-converter) is used to connect this system to the utility grid. Two simulation models of such an inverter have been made: One with a PI-current controller and the other with a hysteresis current controller. Both current control techniques had been studied and analyzed through theory and simulation. Calculations had been made to dimension a LCL filter for the system and to find the average losses in the diode and transistors. Mini-project 15a 2
5 2 INTRODUCTION This chapter will present the objectives and requirements of the project. 2.1 STRUCTURE AND CONTENT OF THE REPORT The report is based on theoretical presentations and simulations on two different kinds of current controllers. Introductory chapters present the task. Chapter 3 gives a theoretical presentation of inverters and current controllers. Chapter 4 deals with calculations. Chapter 5 deals with the main part of the project which is the simulations. The final chapter is devoted to conclusion. Attached zip-file or CD contains data sheet, simulation results, SimPower models and matlab files. 2.2 PROBLEM FORMULATION The desire for increasing their efficiency and reducing the harmful emissions lead to the widely spreading and applying of small-scale generators, which are commonly called distributed generation (DG) units. The attempt to realize the DG potential has led to the appearance of Microgrid concept. The main characteristics of Microgrid concept are: It is a local scale power system with DG units, which produces electrical or thermal energy to the local system demand. It can provide power supplies to the customers with multiple load locations. It creates the possibility of seamless crossing between grid-connected mode and autonomous operation (island mode). It increases the power quality and system reliability. In addition, it provides significant control capabilities over the network operation. Different types of DG units could have different output nature, than the network which they are supposed to work with. Since the existing Microgrids are operating as AC systems, we need to use power electronic interfaces in order to connect DG units. 2.3 WHY WARTSILA WANTS TO WORK WITH THE PROBLEM Wärtsilä is a global leader in complete lifecycle power solutions for the marine and energy markets. Since Wärtsilä is integrating DG units on ships and their power plants are based on renewable energy, they need to use power electronics to connect and control DG units. 2.4 OBJECTIVES OF THE PROJECT During the Miniproject, a simulation model of Inverter for 230 V ac and 20 kw should be created using SimPower. To keep voltage ripples on acceptable level, the parameters of LCL-filter should be chosen. The project group will also compare the behavior of a PWM-modulator with a PIcurrent controller with the behavior of a hysteresis current-controller and calculate the average losses in the diode and transistors. Mini-project 15a 3
6 3 THEORY 3.1 MICROGRID A microgrid is power supply network which is designed to provide power to a certain area. It also can provide the power to centralized grid. Generators and loads are connected at low voltage in micro grid. Sources of power generation related to microgrid are usually renewable energy. The power we get from the renewable energy sources is mostly DC power, so to operate our load which is AC driven we need inverters. Inverters are thus essential part to get energy from renewable energy sources. 3.2 INVERTER Figure 1: Three-phase inverter Inverters convert DC power into AC power. Conversion of this energy is done with a three-phase full bridge inverter and for every single switch we need anti parallel diode. The main idea behind an inverter is to get a pure sinusoidal voltage and current for our AC driven load. To obtain this pure sine wave, we use different components and control methods in the inverter. The component characteristics determine the conduction losses, maximum switching frequency, power handling capability and temperature dependent variables. The control methods will determine the switching frequency. Mini-project 15a 4
7 3.3 CURRENT CONTROLLER ANALYSIS For high performing three phase AC drives, the current controlling technique is of great importance as the characteristics of the inverter such as the switching frequency, level of harmonic distortion and the measure of dynamics in the output response. Two techniques are discussed, PI PWM current controller (linear) and the Hysteresis PWM current controller (non-linear). Figure 2: PWM Current Controller PI PWM CURRENT CONTROLLER. This is a linear current controller known as the proportional-integral regulator. In this technique, the phase current is compared to a reference current value and output error compensated through the PI error compensator whose output is further used to modulate the IGBT (inverter switch) or the PWM. The integral part of the PI compensator minimizes errors at low frequency, while proportional gain and zero placement are related to the amount of ripple [1]. The ripple in the output current is amplified by the gain of the compensator, thus influencing the switching frequency of the switches. This technique requires minimal harmonic frequency below the carrier frequency. The disadvantage is in the tracking error of the output current amplitude and phase [1]. Figure 3: PI PWM current controllers Mini-project 15a 5
8 3.3.2 HYSTERESIS CURRENT CONTROLLER This is one of the mostly used current controller technique because it is very easy to implement as compared to other types. Knowledge of load parameters is not required and its current loop response is faster than others [2]. In the hysteresis technique, actual phase current in a three phase systems is compared with a reference current for the same phase and the error passed through a hysteresis band to generated input pulses to regulate the IGBT for minimal current errors. This is done for three phase currents of the system but with one disadvantage of phase quantity interaction in a three phase system. Each three phase output currents to the load are compared with the respective reference phase currents by three hysteresis comparators for each phase and the output used to activate the inverter switches. But additional circuitry is required since the switching frequency/the ripple current varies at every point of the fundamental frequency. 3.4 LCL FILTER Figure 4: Hysteresis current controllers Figure 5: Three-phase inverter with LCL filter The DC/AC inverter discussed in chapter 3.1 consists of the DC link, three-phase inverter and the filter. To minimize the current harmonics, we need a bulky inductance in the filter to achieve good performance. The LCL filter, consisting of two inductors and one capacitor, is a popular choice because of its better attenuation for switching frequency harmonics and its low cost. However, an LCL filter has its own drawback. Because of the peak at the resonance frequency, the filter will increase instability of the system. To counteract this, we use a damping resistor in series with the capacitors. Mini-project 15a 6
9 4 CALCULATIONS 4.1 DIMENSIONING THE FILTER When dimensioning the LCL filter, the following should be kept in mind. The total inductance should be large to have lower harmonic distortion, but it will also slow down the system response. It is also important to keep in mind that inductance size is proportional to the cost. To have a high power factor, the capacitor should not be too large since it absorbs reactive power. The damping resistor should not be too large since it would produce huge power loss. First a suitable overall inductance value L s is chosen: [3] Where E m is the peak voltage of the grid, I m is the peak current of the grid, f sw is the switching frequency, and i ripple is the current ripple. Since we want a low value of L s for cost reasons, we will use the minimum boundary. The capacitance C f is then chosen: [3] Where q is the percent reactive power we want absorbed, f n is the grid frequency, E n is the rms value of the phase voltage, and P n is the rated power produced by the inverter. The value of the two inductances L 1 and L 2 is dictated by a ratio r: The resonance frequency f res should be check if it is suitable: ( ) Lastly, the damping resistor is calculated: [3] Mini-project 15a 7
10 4.2 CALCULATING AVERAGE POWER LOSS IN THE DIODES AND THE TRANSISTORS The IGBT and Diode power losses (P i), can be divided into two groups: the conduction losses (P cond) and the switching losses (P sw) SWITCHING LOSSES The switching losses in the diode and the IGBT are the product of switching energies and the switching frequency: [4] ( ) ( ) The turn-on energy losses in the IGBT (E ont) can be calculated as the sum of the switch-on energy without taking the reverse recovery process into account (E onti) and the switch-on energy caused the reverserecovery of the free-wheeling (E ontrr). The turn-on energy in the diode consists mostly of the reverserecovery energy (E ondrr). [4] ( ) ( ) ( ) ( ) where U Drr is the voltage across the diode during reverse recovery and Q rr is the diode recovery charge. The turn-off energy losses in the IGBT can be calculated in the similar manner. The switch-off losses in the diode are normally neglected. [4] ( ) ( ) To simplify calculations, typical switching energies given on the data-sheet of the supplier are used CONDUCTION LOSSES The instantaneous value of the IGBT and the diode conduction losses are given: [4] ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) The average conduction losses across the switching period (T sw=1/f sw) are: ( ) ( ) ( ) ( ) ( ) ( ) ( ) ( ) The dynamic resistance values for IGBT and diode (r c and r d) can be read from the data-sheet diagram of the supplier (as shown at the figure below). Since both values are dependent on the junction temperature, we took into account the worst case scenario which is at T j =150 C. Mini-project 15a 8

12 5 SIMULATION 5.1 THE MODEL A simulation model of the specified system was created using SimPower. Figure 7: Simulation model It consists of a three phase full bridge inverter for a 230 Vac and 20 kw load. The inverter has a constant DC voltage source of 680V. An Infineon IGBT with anti-parallel diode IKW40T120 was used. Lastly, a LCLfilter is connected on the AC side of the inverter to minimize ripples. As Figure 8: Current Controllers Two different controllers are used, a hysteresis current-controller and a PWM-modulator with a PIcurrent controller. Mini-project 15a 10
13 Figure 9: Switching frequency checker To determine the average switching frequency of an inverter with a hysteresis current controller, a subsystem was created to measure the switching frequency. This is done by counting the number of rises on a gate signal which basically tells us the number of switches made, and holding the count once the clock reaches the fundamental period. Dividing the number of switches by the fundamental period then gives us the switching frequency. Figure 10: Power loss calculations A subsystem dedicated for power loss calculations was also created, using the equations discussed at chapter 4.2. Mini-project 15a 11
14 Figure 11: Conduction loss calculations Figure 12: Switching loss calculations The LCL filter values are calculated automatically using the equations discussed at chapter 4.1 through a matlab script each start of a new simulation to accommodate changes in input data. Mini-project 15a 12
15 5.2 RESULTS PI PWM CURRENT CONTROLLER WITH F S = 20 KHZ Using 20 khz switching frequency, and assuming 20% current ripple gave us the following values for the LCL filter: L1 14,58 mh Cf 22,17 mf L2 10,2 mh Table 1: LCL Filter for fs = 20 khz Starting with the PI PWM Current Controller, the scope readings below show us how the PWM controller works. When the PI output which is our control voltage is more than the triangular wave voltage, the upper thyristor T A+ is conducting. When the control voltage is less than the triangular wave voltage, the lower thyristor T A- is conducting. Figure 13: PI Controller outputs Mini-project 15a 13
16 The scope readings below shows the effects of the LCL filter. This gives us a THD of 8,98 %. Figure 14: PI controller ripple and load measurements Figure 15: PI Controller THD This setup gives us average IGBT losses of 1506 W and average diode losses of 73 W, giving a total loss of 1579 W. Mini-project 15a 14
17 5.2.2 HYSTERESIS CURRENT CONTROLLER WITH F S = 20 KHZ Using the hysteresis current controller and the same LCL filter values, gave us an average switching frequency of 21 khz. The scope readings below show us how the hysteresis current controller works. If the actual current tries to go beyond the upper tolerance band, T A- is turned on to reduce the current. The opposite switching occurs if the actual current tries to go below the lower tolerance band. Figure 16: Hysteresis Controller outputs The scope readings below shows the effects of the LCL filter. Figure 17: Hysteresis controller ripple and load measurements Mini-project 15a 15
18 This gives us an acceptable THD of 3 %. Figure 18: Hysteresis Controller THD This setup gives us average IGBT losses of 1691 W and average diode losses of 76 W, giving a total loss of 1767 W. Mini-project 15a 16
19 Total Losses (IGBT and Diode) [W] Switching frequency [Hz] Active Rectifier in Microgrid COMPARISONS The figure below shows the effects of the switching frequency to the filter inductance. It shows that as we increase the switching frequency, the value that we need for the filter inductance decreases. It is also important to notice that the hysteresis current controller gives out higher average switching frequency than the PWM PI current controller at similar filter inductance values PWM PI CC Hysteresis CC Filter Inductance Ls [mh] Figure 19: Filter inductance vs switching frequency The figure below shows the effects of the switching frequency to the total loss (in the diode and the transistors) PWM PI CC Hysteresis CC Switching Frequency [Hz] Figure 20: Switching frequency vs total losses Mini-project 15a 17
20 The figure below shows us the effects of variations in the hysteresis band in a hysteresis current controller. This shows us that the THD in a hysteresis current controller is mainly dependent on the hysteresis band. If the hysteresis band increases, THD also increases, but the switching frequency decreases, which gives less switching losses. 4,50 4,00 3,50 3,00 2,50 2,00 1,50 1,00 0,50 0,00 9,90 14,84 19,80 24,75 29,70 Hysteresis Band [A] fs [10^4 Hz] Power loss [kw] THD [%] Figure 21: Hysteresis band variation effects Mini-project 15a 18
21 6 CONCLUSION Current control techniques can be divided into two groups: linear (PI Controller) and non-linear controllers (Hysteresis CC). The basic principles of these techniques have been described in the report. Both have its advantages and limitations. The advantage of the PI controller is that it gives out constant switching frequency, which provides a stable operation of the inverter. The main disadvantage of this technique is an inherent tracking (amplitude and phase) error. The advantage of the hysteresis band controller lies in its simplicity and its providing of excellent dynamic performance. On the other hand, the disadvantage is that the switching frequency varies, providing irregular operation of the inverter. As a result the switching losses are increased. In addition to studying the two current control techniques, the project group also studied how to dimension a LCL filter and how to calculate power losses in the IGBT and the diode.
