Comparison of PSS, SVC and STATCOM Controllers for Damping Power System Oscillations
نویسندگان
چکیده
This paper discusses and compares different control techniques for damping undesirable inter-area oscillation in power systems by means of Power System Stabilizers (PSS), Static Var Compensators (SVC) and Shunt Static Synchronous Compensators (STATCOM). The oscillation problem is analyzed from the point of view of Hopf bifurcations, an “extended” eigen analysis to study different controllers, their locations, and the use of various control signals for the effective damping of these oscillations. The comparisons are based on the results obtained for the IEEE 50machine, 145-bus test system, which is a benchmark for stability analysis.

Damping of Power System Oscillations by using coordinated tuning of POD and PSS with STATCOM
Static synchronous compensator (STATCOM) is a shunt connected voltage source converter (VSC), which can affect rapid control of reactive flow in the transmission line by controlling the generated a.c. voltage. The main aim of the paper is to design a power system installed with a Static synchronous compensator (STATCOM) and demonstrates the application of the linearised Phillips-heffron model i...

In this paper, a lead-lag structure is proposed as a main damping controller for a static VAR compensator (SVC) to diminish power system oscillations. To confirm the transient performance of the proposed controller, it was compared to a proportional integral derivative (PID) damping controller. Power system stability improvement was thoroughly examined using these supplementary damping controll...
