This paper deals with one of the potential applications of distribution static compensator (DSTATCOM) to industrial systems for mitigation of voltage dip problem. The dip in voltage is generally encountered during the starting of an induction motor. Isolated distribution systems are comparatively not as stiff as grid systems; so large starting currents and objectionable voltage drop during starting of an induction motor could be critical for the entire system. DSTATCOM is one effective solution for isolated power systems facing such power quality problems. The model of DSTATCOM connected in shunt configuration to such an isolated system (3phase, 42.5 kVA alternator) feeding dynamic motor loads is developed using Simulink and PSB of MATLAB software. Simulated results demonstrate that DSTATCOM can be a considered as a viable solution for solving such voltage dip problems

This paper deals with the design, analysis and simulation of neural network based DSTATCOM controller. Conventional controllers being fixed structure provide optimum performance only over a limited range of operating conditions for which they are designed. Alternate controllers based on fuzzy logic and neural networks are more robust and can be designed to operate well under a wide range of operating conditions. This paper highlights the performance of artificial neural network (ANN) based DSTATCOM controller with respect to PI controllers.

This paper deals with a DSTATCOM (distribution static compensator) for load balancing, neutral current elimination, power factor correction and voltage regulation in three-phase, four-wire distribution system feeding commercial and domestic consumers. A four leg voltage source inverter (VSI) configuration with a DC bus capacitor is employed as DSTATCOM. The modified instantaneous reactive power theory (IRPT) is used in the control of DSTATCOM. The capability of the DSTATCOM is demonstrated through results obtained using MATLAB based developed model of the system at different types of loads.

This paper focuses on power quality improvement with DSTATCOM on a small, isolated 42.5 kVA alternator feeding a three-phase, three-wire distribution system. Some power quality aspects like power-factor correction, voltage regulation and load balancing of linear load are discussed and implemented using DSTATCOM. DSTATCOM is realized using a three leg IGBT based PWM-VSI bridge having a DC bus capacitor. A hysteresis rule based carrier-less PWM current controller is used to derive gating pulses for the IGBT switches. The models are developed and simulated in MATLAB using Simulink and Power System Blockset (PSB) toolboxes. It is observed that DSTATCOM is effective in compensating reactive power and improving the power quality of the distribution system
