ABSTRACT: In large inter connected
power systems, inter-area oscillations are turned to be a severe problem. Hence
inter-area oscillations cause severe problems like damage to generators, reduce
the power transfer capability of transmission lines, increase wear and tear on
network components, increase line losses etc. This paper is to maintain the
stability of system by damping inter-area oscillations. Implementation of new equipment consists of high power
electronics based technologies such as FACTs
and proper controller design has become an essential to provide better damping performance
than Power System Stabilizer (PSS). With development of Wide Area Measurement
System (WAMS), remote signals have become as feedback signals to design Wide
Area Damping Controller (WADC)
for FACTs devices. In this work,
POD is applied to both SVC and SSSC. Simulation studies are carried out in Power System Analysis Toolbox (PSAT) environment to
evaluate the effectiveness of the FACTs controller in a large area power
system. Results show that extensive analysis of FACTs controller for improving
stability of system.
