MHAROUS** *Electrical Engineering Department, Faculty of Engineering, Menoufiya University Shebin El-Kom, Egypt **International Steel Rolling Mill Company (ISRM), Sadat, Egypt ABSTRACT: This paper presents a shunt active power filter to compensate reactive power and reduce the unwanted harmonics. A shunt active filter is realized employing three-phase voltage source inverter (VSI) bridge with common DC bus capacitor. The shunt active filter acts as a current source, which is connected in parallel with a nonlinear load and controlled to generate the required compensation currents. Two different proposed control methods for determining the reference compensating currents of the three-phase shunt active power filters based on proportional-integral (PI) controller and Artificial Neural Network (ANN) are presented. Current controller based on modified hysteresis current controller is used to generate the firing pulses. The proposed system is implemented using a high speed Digital Signal Processor (DSP). Experimental and simulation results with different nonlinear loads are presented to confirm the validity of the proposed technique. KEYWORDS: Active Power Filter, Current Control, Artificial Neural Network INTRODUCTION The increasing use of power electronic loads in industry and by consumers results in a considerable amount of harmonic injection, and lower power factor [-2]. Conventionally, passive filters have been used to eliminate current harmonics and to increase the power factor. However, the use of passive filter has many disadvantages [3- ]. Recently, because of the rapid progress in modern power electronic technology, the presented work was oriented mostly on the active filters instead of passive filters [6-8]. The basic difference between passive and active filters is that the active filters have the capability to compensate random varying currents [9-4]. One of the most popular active filters is the shunt active power filter (SAF). The SAF s have been researched and developed, that they have gradually been recognized as a feasible solution to the problems created by nonlinear loads. They are used to eliminate the unwanted harmonics and compensate fundamental reactive power consumed by nonlinear loads through injecting the compensation currents into the AC lines. In addition to eliminating harmonic currents and improving the power factor, SAF can keep the power system balance under the condition of unbalanced and nonlinear loads [9-]. enerally, The performance of SAF is based on three design criteria [-22]: i) design of power inverter; ii) types of current controllers used; iii) methods used to obtain the reference current. Many control techniques have been used to obtain the reference current. These techniques such as instantaneous reactive power theory [], notch filters [8], flux based controller [9], power balance theory [8]-[22], and sliding mode controller [6]-[7] have been used to improve performance of the active filters. However, most of these control techniques

2 44 ACTA ELECTROTEHNICA include a number of transformations and are difficult to implement [9]. This paper presents two different approaches used to calculate the reference current of the SAF. The first technique used the DC capacitor voltage with PI controller. Although, this method is simple to implement and achieves good results, it had drawbacks at unbalance conditions of the supply voltages. The performance of the SAF is achieved by the second technique, which depends on an ANN. The output of the ANN is used to generate the reference currents of SAF. The basic objective of this control is to provide a very precise solution to get the reference current even under unbalanced conditions of supply voltages. A hysteresis controller based on PWM current control is used, which is widely used due to its fast response. Comparisons of simulation results are presented for the two control strategies. The proposed control system with ANN is implemented using a DSP. Experimental results were presented to prove the effectiveness of the design of the control strategy. SYSTEM DESCRIPTION AND OPERATION Power Circuit Description: As shown in Fig., the SAF system consists of a three-phase voltage inverter with current regulation, which is used to inject the 3-phase AC supply compensating current into the power line. The VSI contains a three-phase Isolated ate Bipolar Transistors (IBT) with antiparalleling diodes. The VSI is connected in Parallel with the three-phase supply through three inductors L f, L f2 and L f3. The DC side of the VSI is connected to a DC capacitor, C, that carries the input ripple current of the inverter and the main reactive energy storage element. The DC capacitor provides a constant DC voltage and the real power necessary to cover the losses of the system. The inductors L f, L f2 and L f3 perform the voltage boost operation in combination with the capacitor, and at the same time act as the low pass filter for the AC source current. Then the SAF must be controlled to produce the compensating currents i f, i f2 and i f3 following the reference currents i f *, i f2 * and i f3 * through the control circuit. System Modeling: The representation of a three-phase voltages and currents of the VSI in Fig. () are as follows: the voltages V f, V f2 and V f3 supplied by the inverter as a function of the capacitor voltage, V c, and the state of the switches, 3 and are : V f V f2 V f3 S S 3 S L f D D D i f L f2 if2 C i f3 D D D L f3 S 4 = V c () where, 3 and represent three logic S 6 S 2 i f Vs Control V c i L Non linear Load Fig..

Then the SAF currents can be written as: di L f f = Vs V f (2) dt di L f 2 f2 = Vs2 V f2 (3) dt di L f 3 f3 = Vs3 - V f3 (4) dt where i f, i f2 and i f3 are SAF currents and, 2 and 3 are the supply voltages. The voltage in the DC capacitor can be calculated from the SAF currents and switching function as follows: Vc [ = i i i C f 3 f2 f3 ] () The set point of the storing capacitor voltage must be greater than the peak value of the line neutral mains voltage in order to be able to shape properly the mains currents. THE PROPOSED CONTROL METHODS The quality and performance of the SAF depend mainly on the method implemented to V S X i * S i L generate the compensating reference currents. This paper presented two methods to get the reference current, which is key issue in the control of the SAF. Capacitor Voltage With PI Controller: The basic operation of this proposed control method is shown in Fig. 2. The estimation of the reference currents from the measured DC bus voltage is the basic idea behind the PI controller based operation of the SAF. The capacitor voltage is compared with its reference value, V c *, in order to maintain the energy stored in the capacitor constant. The PI controller is applied to regulate the error between the capacitor voltage and its reference. The output of PI controller is multiplied by the mains voltage waveform, 2, 3 in order to obtain the supply reference currents i s *, i s2 *, i s3 *. Then the supply reference currents are proportional to the mains voltages. The three-phase compensating reference current of SAF (i f *, i f2 *, i f3 *) are estimated using reference supply currents and sensed load currents. Proposed control method with ANN: This method is based on the recovering of the fundamental active phase currents in i * f i f Hysteresis current controller 4 V c V * c PI V S2 V S3 X i L2 i * S2 i L3 i * f2 i f i f Distribution circuit 3 6 X i * S3 i * f3 2 Fig. 2.

Once these currents are obtained, they are subtracted from the total load currents to get the desired reference waveform. Let to assume that the nonlinear load current can be represented as: n n= 2 i = i cosϕ sin wt i sinϕ cos wt i l sin( nwt ϕ ) = ip ( t) iq ( t) ih ( t) (6) where i p (t) represents the active current, i q (t) represents the reactive current and i h (t) represents the sum of all harmonic currents. If the SAF can generate i f (t) which is equivalent to i q (t)i h (t), then the mains only needs to supply the active current i p (t), which is a sine wave and in phase with the supply voltage (t). Equation (6) becomes; i f (t) = i L (t) i p (t) = i L (t)- I cos(φ) sin(ωt) where sin(ωt) = /V m (7) i f (t) = i L (t)-w (t) where W=I cos(φ)/v m (8) According to calculation of W, the reference current of the SAF is easy to calculate which changes according to the nonlinear load current and the supply voltage. The calculation of W is based on neural n network. The basic principle diagram of this control algorithm is shown in Fig. 3. The ANN in Fig. 3 consists of a neuron that is an adaptive linear element, the weigh of the neuron is equivalent W and the bias is equivalent to zero. The input of the system is the supply voltage (t), the output of the ANN is fundamental active current i p (t) and the output of the system is the SAF reference current i f *. According to The Widrow-Hoff learning rule, the update weight equation as follows: W(n) =W(n-) η i fr (n-) (9) where the term η i fr (n-) is represents the change of weight. i fr (n) = i L (n)-w(n) (n) () From equations (9) and (), the proposed control method for phase-a is designed, as shown in Fig. 4. The neural network learning and training by Widrow-Hoff learning rule is used to obtain the weight (W). Then the SAF reference current can be calculated from the equation (). After calculating the reference current for the SAF, the hysteresis current controller has been presented to provide the i L - i p * f i X W Z - X η Z - Fig. 4. The proposed control method for phase-a.

Hysteresis current controller: Hysteresis current controller with fixed band derives the switching signals of the inverter from the comparison of the current error to keep the current within the hysteresis band. Then the SAF reference currents i f *, i f2 *, i f3 * compared with SAF feedback currents i f, i f2, i f3 and the error signals are operated by the hysteresis current controller to generate the firing pulses which activate the inverter power switches in a manner that reduces the current error. Let (h b ) is the width of the hysteresis band around respective phase SAF currents, then the equation for the fixed band as follows: i f * = i max sin(ωt) () i up = i f * h b (2) i low = i f * - h h (3) where i up is the upper band, i low is the lower band. If the SAF current feedback i f > (i f * h b ) then = -, which means that the inverter output voltage switches to negative, in order to keep the current within the hysteresis band. If the SAF current feedback i f < (i f * - h b ) then =, which means that the inverter output voltage switches to positive, in order to increase the actual current. Similarly, the switching logic of other two-phase 2, 3 is derived. SIMULATION RESULTS A number of simulation results with different operating conditions were developed. In Fig., SAF is connected in parallel with nonlinear load. Then, the threephase controlled rectifier with resistive load has to be compensated by the SAF. In order to limit maximum slope of the rectifier current, a smoothing inductor, L r, has been inserted before the rectifier. Also, it is prevented the inverter saturation even in correspondence of rectifier commutations. Since the compensation of the filter depends upon the firing angle (α) of the rectifier, two operative conditions have been considered. The uncontrolled rectifier is the first case, while the second one is the controlled rectifier with firing angle α=4. The parameters of system are reported in Appendix. Simulation with uncontrolled rectifier (α = ): Steady state operations: The simulation results in steady state operation are presented. Figure 6 shows the performance of the SAF system using PI controller. Waveform of the source current without SAF is shown in Fig. 6-a.

Also, the current isolators using LEM hall-effect current sensors sense the compensating current. The control scheme is implemented in real time using a 32-bit digital signal processor (DSP-TMS32C3). The control algorithm generates three-phase reference supply currents, which are the output of DSP. The three-phase reference supply currents are fed to hysteresis PWM current controller. The resulting pulses are gating the IBT s of the SAF. Figure shows experimental waveforms for the load condition of uncontrolled rectifier. The power factor is improved to unity using ANN control technique. Figure -a shows the supply voltage and current without ASF. Figure -b shows the supply phase voltage, supply current and its reference. It is clear from Fig. -b that the supply current is almost sin waveform and follows the supply voltage in its waveform shape with almost a unity displacement power factor. Figure -c shows the compensating current. From these figures, it is clear that the effectiveness of the proposed controller for active power filter. CONCLUSION A control strategy for high performance three-phase shunt active filter with unity input power factor has been proposed. Two control strategies are considered, the first is PI-controller and the second is based on ANN. The control scheme using three independent hysteresis current controllers has been implemented. The operation and modeling of the SAF have been described.
