Abstract |
|
In this research a dual compensating scheme based UPQC (Unified Power Quality Conditioner) controller has been designed for compensating source condition for all non-linear loading. The focus of the research is to mitigate harmonics in the supply system generated due to nonlinear loading and maintain the supply profile at all adverse conditions. UPQC is featured with dual compensation strategy such that it employs two converters. One is connected in series through a coupling transformer. Another is in parallel connected at load side. The controlled quantities are in synchronous frame. This simplifies the control algorithm of the topology. The performance of the system has been examined under various nonlinear loadings. |
