Simulation of Unified Power Flow Controller Closed Loop and Interline Power Flow Controller For Closed and Open Loop Using Pspice

摘要

The Unified Power Flow Controller (UPFC) is a versatile controller which be able to be used to manage the vigorous in addition to reactive power in the line independently. The solid state controllers are used to practically handle problems involving compensation of transmission lines and power flow control problems with the concept of UPFC. To improve power quality in the distribution systems, various solutions were developed and implemented, namely active filters, unified power flow filters (UPFC), Interline power flow controllers. An Interline Power Flow Controller is a series or series-parallel filters applied to several independent lines with a common DC element. Basically an interline power Flow Controllers a VSC-based Flexible AC grid System (FACTS) controller intended for series compensation with the distinctive capacity of power flow administration amongst multi-lines of a substation. In this project basic characteristics of IPFC are discussed. By this scheme maximum system asset is utilized. Initially modeling and simulation of SSSC (UPFC) is done, since the IPFC is series parallel combination of converter and line. Then the modeling and simulation of IPFC is done using Pspice software package. The performance characteristics of the IPFC are studied and the results are presented.
