1 PERFORMANCE ANALYSIS OF FACTS (D-STATCOM AND DVR) DEVICES Manoj Garg 1 & Rajeev Kumar 2 1 Research Scholar, GIMT, Kurukshetra, Haryana, India 2 Assistant Professor, GIMT, Kurukshetra, Haryana, India Abstract The Power Quality Analysis aspires to bring out electricity consumers for improved power quality with application of power electronics. The research work involves in-depth analysis of the interaction among loads, power networks and various power quality improvement devices. It ultimately leads to better design of mitigation devices like Dynamic Voltage Restorer (DVR), Distribution Static Synchronous Compensator (DSTATCO M) and Unified Power Quality Conditioner (UPQC) to alleviate various power quality related problems. The main objective of this research work is to develop a model of DVR and DSTATCO M for enhancement of power quality. DVR and DSTATCO M are among the custom power devices that are used as an effective solution for the protection of sensitive loads against voltage disturbances in power distribution system. The efficiency of the FACTS devices depends on the performance of the control technique, which involved in switching the inverters. A comparative analysis of PI controlled DVR and DSTATCO M has been carried out for better power system stability enhancement. The validity of the proposed method and achievement of the desired compensation are confirmed by the results of the simulation in Matlab/ Simulink. 1. INTRO DUCTIO N Power quality is a word that means different things to different inhabitants. Institute of Electrical and Electronic Engineers (IEEE) Standard IEEE1100 defines power quality as, The conception of powering and grounding sensitive electronic equipment in a manner suitable for the equipment. As suitable as this description might seem, the drawback of power quality to sensitive electronic equipment might be subject to deviation. Electrical equipment susceptible to power quality or more appropriately to need of power quality would fall within an apparently boundless domain. All electrical devices are prone to failure or breakdown when exposed to one or more power quality problems. The electrical device might be an electric motor, a transformer, a generator, a computer, a printer, communication equipment or a home appliance. All of these devices and others react undesirably to power quality issues, depending on the severity of problems. However, nearly everybody accepts that it is a very important aspect of power systems and electric machinery with direct impacts on efficiency, security and reliability. Various sources use the term power quality with different meaning. It is used synonymously with supply reliability, service quality, voltage quality, current quality, quality of supply and quality of consumption. Nonlinear loads generate harmonic currents that can promulgate to other locations in the power system and ultimately return back to the source. Therefore, harmonic current promulgation produces harmonic voltages throughout the power systems. Many mitigation techniques have been suggested and employed to maintain the harmonic voltages and currents within proposed levels. 1. Design of High power quality equipment, 2.

Harmonic filters (passive, active and hybrid) and custom power devices such as active power line conditioner (APLC), DVR, DSTATCOM and Unified Power Quality Conditioners. The phenomenon of power quality through application of power electronics is studied in the research work. The aim of the control scheme is to develop Simulink model of DVR and DSATCOM maintain constant voltage magnitude at the point where a sensitive load is connected, under system disturbances. The wide range of power quality disturbances covers sudden, short duration variations, e.g. impulsive and oscillatory transients, voltage sags, short interruptions, as well as steady state deviations, such as harmonics mitigation by using DVR. This research work, specifically examine the use of a power electronic shunt compensator named as DSTATCOM to correct the current drawn from a utility to closely approximate balanced sinusoidal waveforms, without adversely affecting the voltage at the point of common coupling. Thus, adjustment of the feedback gains makes it possible to reduce voltage fluctuation in transient states, when the active filter has the function of combined harmonic damping and voltage regulation. By using UPQC the control scheme of a shunt active power filter must calculate the current reference waveform for each phase of the inverter, maintain the dc voltage constant and generate the inverter gating signals. To correct for the effects of supply voltage distortion, the series compensator is required to inject appropriate harmonic voltages. A novel strategy for the improvement of power quality based on custom power devices the analysis of the results obtained from various techniques, ijrrest.org 5 P a g e
2 like PI Controller and Fuzzy Logic Controller are presented. The main objectives of the research work are to develop model for DVR for the enhancement of power quality in electrical power networks. The objective which has been laid down for this work is the development of DVR and DSTATCOM model simulation model and their performance analysis through simulation. Research has been carried out to achieve the above mentioned objectives. The effectiveness of the DSTATCOM and DVR in solving the power quality problems has been proved through simulations, model development and analysis. Custom power devices transient performance observed. Control techniques developed to overcome the problems related to DC Link voltage deviations. produces fewer harmonic than a single bridge, resulting in smaller filters and improved dynamic response. In this case, the inverter modulation frequency is 28*60=1.68 khz so that the first harmonics will be around 3.36 khz. LC damped filters connected at the inverter output. Resistances connected in series with capacitors provide a quality factor of 40 at 60 Hz. a microfarad capacitor acting as a DC voltage source for the inverter a voltage regulator that controls voltage at bus B3 a PWM pulse generator using a modulation frequency of 1.68 khz Anti-aliasing filters used for voltage and current acquisition. 2. D-STATCO M MO DEL DESCRIPTIO N A Distribution Static Synchronous Compensator (D- STATCOM) is used to regulate voltage on a 25-kV distribution network. Two feeders (21 km and 2 km) transmit power to loads connected at buses B2 and B3. A shunt capacitor is used for power factor correction at bus B2. The 600-V load connected to bus B3 through a 25kV/600V transformer represents a plant absorbing continuously changing currents, similar to an arc furnace, thus producing voltage flicker. The variable load current magnitude is modulated at a frequency of 5 Hz so that its apparent power varies approximately between 1 MVA and 5.2 MVA, while keeping a 0.9 lagging power factor. This load variation will allow you to observe the ability of the D-STATCOM to mitigate voltage flicker. The D-STATCOM regulates bus B3 voltage by absorbing or generating reactive power. This reactive power transfer is done through the leakage reactance of the coupling transformer by generating a secondary voltage in phase with the primary voltage (network side). This voltage is provided by a voltage-sourced PWM inverter. When the secondary voltage is lower than the bus voltage, the D- STATCOM acts like an inductance absorbing reactive power. When the secondary voltage is higher than the bus voltage, the D-STATCOM acts like a capacitor generating reactive power. The D-STATCOM consists of the following components: a 25kV/1.25kV coupling transformer which ensures coupling between the PWM inverter and the network. The D-STATCOM controller consists of several functional blocks: a Phase Locked Loop (PLL). The PLL is synchronized to the fundamental of the transformer primary voltages. two measurement systems. Vmeas and Imeas blocks compute the d-axis and q-axis components of the voltages and currents by executing an abc-dq transformation in the synchronous reference determined by sin(wt) and cos(wt) provided by the PLL. an inner current regulation loop. This loop consists of two proportional-integral (PI) controllers that control the d-axis and q-axis currents. The controllers outputs are the Vd and Vq voltages that the PWM inverter has to generate. The Vd and Vq voltages are converted into phase voltages Va, Vb, Vc which are used to synthesize the PWM voltages. The Iq reference comes from the outer voltage regulation loop (in automatic mode) or from a reference imposed by Qref (in manual mode). The Id reference comes from the DC-link voltage regulator. an outer voltage regulation loop. In automatic mode (regulated voltage), a PI controller maintains the primary voltage equal to the reference value defined in the control system dialog box. a DC voltage controller which keeps the DC link voltage constant to its nominal value (Vdc=2.4 kv). The electrical circuit is discretized using a sample time Ts=5 microseconds. The controller uses a larger sample time (32*Ts= 160 microseconds). a voltage-sourced PWM inverter consisting of two IGBT bridges. This twin inverter configuration, ijrrest.org 6 P a g e
3 Fig. 1 Simulation & Model of DSTATCOM 2.1 D-STATCOM DYNAMIC RESPONSE During this test, the variable load will be kept constant and you will observe the dynamic response of a D-STATCOM to step changes in source voltage. Check that the modulation of the Variable Load is not in service (Modulation Timing [Ton Toff]= [0.15 1]*100 > Simulation Stop time). The Programmable Voltage Source block is used to modulate the internal voltage of the 25-kV equivalent. The voltage is first programmed at pu in order to keep the D-STATCOM initially floating (B3 voltage=1 pu and reference voltage Vref=1 pu). Three steps are programmed at 0.2 s, 0.3 s, and 0.4 s to successively increase the source voltage by 6%, decrease it by 6% and bring it back to its initial value (1.077 pu). Note that when the D-STATCOM changes from inductive to capacitive operation, the modulation index of the PWM inverter is increased from 0.56 to 0.9 (trace 4 of Scope2) which corresponds to a proportional increase in inverter voltage. Reversing of reactive power is very fast, about one cycle, as observed on D-STATCOM current (magenta signal on trace 1 of Scope1). Start the simulation. Observe on Scope1 the phase A voltage and current waveforms of the D-STATCOM as well as controller signals on Scope2. After a transient lasting approximately 0.15 sec., the steady state is reached. Initially, the source voltage is such that the D-STATCOM is inactive. It does not absorb nor provide reactive power to the network. At t = 0.2 s, the source voltage is increased by 6%. The D-STATCOM compensates for this voltage increase by absorbing reactive power from the network (Q=+2.7 Mvar on trace 2 of Scope2). At t = 0.3 s, the source voltage is decreased by 6% from the value corresponding to Q = 0. The D-STATCOM must generate reactive power to maintain a 1 pu voltage (Q changes from +2.7 MVAR to MVAR). Fig. 2 DSTATCOM in dynamic mode (Scope 1), ijrrest.org 7 P a g e
4 2.2 MITIGATION OF VOLTAGE FLICKER During this test, voltage of the Programmable Voltage Source will be kept constant and you will enable modulation of the Variable Load so that you can observe how the D-STATCOM can mitigate voltage flicker. In the Programmable Voltage Source block menu, change the "Time Variation of" parameter to "None". In the Variable Load block menu, set the Modulation Timing parameter to [Ton Toff]= [0.15 1] (remove the 100 multiplication factor). Finally, in the D-STATCOM Controller, change the "Mode of operation" parameter to "Q regulation" and make sure that the reactive power reference value Qref (2nd line of parameters) is set to zero. In this mode, the D- STATCOM is floating and performs no voltage correction. Run the simulation and observe on Scope3 variations of P and Q at bus B3 (1st trace) as well as voltages at buses B1 and B3 (trace 2). Without D-STATCOM, B3 voltage varies between 0.96 pu and 1.04 pu (+/- 4% variation). Now, in the D-STATCOM Controller, change the "Mode of operation" parameter back to "Voltage regulation" and restart simulation. Observe on Scope 3 that voltage fluctuation at bus B3 is now reduced to +/- 0.7 %. Fig. 3 controller of DSTATCOM in dynamic mode (Scope 2) The D-STATCOM compensates voltage by injecting a reactive current modulated at 5 Hz (trace 3 of Scope3) and varying between 0.6 pu capacitive when voltage is low and 0.6 pu inductive when voltage is high.

5 active power transfer capability. This active power is transferred via the dc link, and is supplied either by a diode bridge connected to the ac network, a shunt connected PWM converter or by an energy storage device. It works as a harmonic isolator to prevent the harmonics in the source voltage reaching the load in addition to balancing the voltages and providing voltage regulation. Fig. 8 Dynamic Voltage Restorer Fig. 6 Controller of DSTATCOM in Mitigation of voltage flickering mode (Scope 2) The Three-Phase Source block implements a balanced three-phase voltage source with an internal R-L impedance. The three voltage sources are connected in Y with a neutral connection that can be internally grounded or made accessible. You can specify the source internal resistance and inductance either directly by entering R and L values or indirectly by specifying the source inductive short-circuit level and X/R ratio The three-phase inductive short-circuit power, in volts-amperes (VA), at specified base voltage, used to compute the internal inductance L. This parameter is available only if Specify impedance using short-circuit level is selected. The internal inductance L (in H) is computed from the inductive threephase short-circuits power Psc (in VA), base voltage Vbase (in Vrms phase-to-phase), and source frequency f (in Hz) as follows: The Three-Phase Fault block uses three Breaker blocks that can be individually switched on and off to program phase-to-phase faults, phase-to-ground faults, or a combination of phase-to-phase and ground faults. Fig. 7 Bus Data of bus 1 & bus 3 in Mitigation of voltage flickering mode (Scope 3) 3. DYNAMIC VO LTAGE RESTO RER (DVR) DVR injects a voltage component in series with the supply voltage as shown in figure-4.21, thus compensating voltage sags and swells on the load side. Control response is on the order of 3msec, ensuring a secure voltage supply under transient network conditions. Voltage injection of arbitrary phase with respect to the load current implies Fig. 9 Three-Phase Fault with breakers The ground resistance Rg is automatically set to 106 ohms when the ground fault option is not programmed. For example, to program a fault between the phases A and B you need to select the Phase A Fault and Phase B Fault block parameters only. To program a fault between the phase A and the ground, you need to select the Phase A, ijrrest.org 9 P a g e
6 Fault and Ground Fault parameters and specify a small value for the ground resistance. If the Three-Phase Fault block is set in external control mode, a control input appears in the block icon. The control signal connected to the fourth input must be either 0 or 1, 0 to open the breakers, 1 to close them. If the Three-Phase Fault block is set in internal control mode, the switching times and status are specified in the dialog box of the block. Series Rp-Cp snubber circuits are included in the model. They can be optionally connected to the fault breakers. If the Three- Phase Fault block is in series with an inductive circuit, an open circuit or a current source, you must use the snubbers. In the proposed simulink model DVR has been modeled using IGBT based voltage converter. The effectiveness of DVR has been checked by introducing a three phase fault at 0.4 sec. the output waveform is compared in two condition, with and without using DVR. The PI-controlled DVR has proven its effectiveness as analysed from the output waveforms. Fig. 10 DVR model simulated with PI controller 4. CO NCLUSION AND FUTURE SCO PE The conclusions drawn from the different aspects of the study in this research work are summarized in this chapter. The scope for further study in this area is also dwelt upon at the end. Fig. 11 output waveform on occurring fault at 0.4seconds of waveform on occurring fault Fig. 12 Expended view of waveform on occurring fault using PI controller After analyzing output waveforms on occurring fault at 0.4seconds we can conclude that using DVR we can maintain power quality using different control strategies. Nonlinear loads produce harmonic currents that can propagate to other locations in the power system and eventually return back to the source. Therefore, harmonic current propagation produces harmonic voltages throughout the power systems. Mitigation techniques have been proposed and implemented to maintain the harmonic voltages and currents within recommended levels are harmonic filters passive, active and hybrid) and custom power devices DSATATCOM and DVR. The different sources and occurrences of voltage Sags, swells and interruptions have been presented. DSTATCOM and DVR with PI Controller has been designed to mitigate the effects of the power quality problems during different faults like three phase fault, single line to ground fault and double line fault. The performance analysis with two different control techniques gives equally effective results. Any one of the proposed control technique will be equally effective in the successful, ijrrest.org 10 P a g e
7 operation of DVR. The investigation of results performance has been successfully demonstrated in MATLAB/Simulink.
