This paper discusses the application of Distribution Static Compensator (DSTATCOM) to a small distribution system supplied from 42.5kVA diesel generator. The isolated system is not supported from the grid and is prone to a variety of system disturbances and faults. The shunt compensator is modelled, simulated and its performance is studied under load perturbations. To meet the real power needs, a...
A new topology of DSTATCOM (distribution static compensator) consisting of a H-bridge VSC (voltage source converter) and a star/delta transformer is proposed for power quality improvement in a three-phase four-wire distribution system. The star/delta transformer provides isolation to the H- bridge VSC as well as mitigates the zero sequence current in a three-phase four-wire distribution system. The...
In this paper, a new topology of DSTATCOM (Distribution Static Compensator) is proposed consisting of a two-leg VSC (voltage source converter) and a zig-zag transformer for power quality improvement in three-phase four-wire distribution systems. The DSTATCOM along with a zig-zag transformer is employed for the compensation of reactive power for the voltage regulation or power factor correction along...
With the deregulation of the electric power energy market, providing quality power has become an important concern of both power suppliers and customers. Efforts have been made to improve the power quality using passive filters, active power filters, hybrid filters and the new concept of custom power. This paper presents a comprehensive review of compensating custom power devices mainly DSTATCOM (distribution...
