| Abstract |
This paper proposes a new auxiliary Subsynchronous Damping Controller (SSDC) for the Static VarCompensator (SVC) to damp out subsynchronous oscillations in power system containing series compensated transmission lines. The arrival of Wide Area Measurement (WAM) technology has madeit possible to measure the states of a large power system interconnected with synchronized PhasorMeasurement Units (PMU). This paper presents the idea of using remote signals obtained from PMUto damp SSR. An auxiliary subsynchronous damping controller (SSDC) has been proposed for a SVC,using the generator rotor speed deviation signal as the stabilizing signal to damp subsynchronousoscillations. Sturdiness of the controller has been examined by applying the disturbances in the systemthat causes significant changes in generator's operating point. The IEEE Second Benchmark (SBM)model is used for the analysis and the SVC is simulated using the Power System Block set (PSB) inthe MATLAB/Simulink environment. |
