Design Consideration for Configuration, Topology & Control Schemes of DSTATCOM Implemented on Distribution Systems

With the increasing need of electrical energy, the demand for receiving the high quality electrical energy is being increased in distribution systems. But due to the different disturbances affecting the power quality, the power quality in the present day distribution systems is deteriorated due to high reactive power burden, harmonic current, load unbalance, excessive neutral current etc. There are various power quality problems faced by utilities, industrial consumer, equipment like PLC (Programmable Logic Controller), & ASD (Adjustable Speed Drives).The different custom power devices are available for mitigation of power quality problems. DSTATCOM (Distribution Static Compensator) is one of the shunt connected device used for compensating various power quality problems in distribution systems. This paper presents a comprehensive review of DSTATCOM configuration, topology & different control schemes used for power quality improvement on distribution system incorporating multiple applications. 
