Enhancement of Load Voltage Profile in Isolated Substations and Multiple Loop Distribution Systems using FACTS Devices

T. Sridevi


Abstract: This paper presents the line loss minimum condition in isolated substations and same substation multiple loop distribution systems by using the unified power flow controller (UPFC). The continuous demand in electric power system network has caused the system to be heavily loaded leading to voltage instability. Under heavy loaded conditions there may be insufficient reactive power causing the voltages to drop. This drop may lead to drops in voltage at various buses. The result would be the occurrence of voltage collapse which leads to total blackout of the whole system. Recent research in distribution networks has been focused on minimizing power loss and enhances load voltage profile along the feeders by using power electronics technologies. The idea given in has been achieved using STATCOM, SSSC, and Active Filters based shunt and series power converters to compensate reactive power in distribution systems, and hence control the power flow. But these devices can do either series or shunt compensation only To overcome this problem this paper focuses on line loss minimum conditions in loop distribution systems by using Unified Power Flow Controller (UPFC). It can do both series and shunt compensation
