摘要：The topology and control of three-phase 4-wire DSTATCOM consisting of a operating flexibility in the DSTATCOM consisting of a operating flexibly in the voltage or current control mode. In the voltage control DSTATCOM topology includes three single-phase voltage source converters connected in parallel. The proposed DSTATCOM provides the voltage regulation of power factor correction along with harmonics elimination, load balancing and neutral current compensation in 3-phase 4-wire system. Fuzzy logic techniques are primarily applied since quick control strategy is needed and imprecise and qualitative definition of action plans are available. While designing an optimal fuzzy controller, one has to look for two primary activities. There are find optimal membership functions for control and action variable, find an optimal set of rules between control and action variable.
