Board of International Research in DesignInstallation of a shunt thyristor-controlled reactive power compensator, the static VAR compensator (SVC), is for the voltage support at a key location in a power system. An additional stabilizing signal can be superimposed on the voltage control loop of the SVC to provide extra damping to the power system.

Substance

Introduction,the oscillation frequency from 0.1 Hz up to a couple of Hz. Once started, the oscillations can continue for a while and then disappear, or grow continuously to cause power system collapse. In this book, they are called power system oscillations or power oscillations for short.

A Multi-machine Power System Installed with Power System Stabilizers,stem is used in this section to demonstrate the procedure of establishing the mathematical model of a multi-machine power system. Later, it will be used for introducing basic concepts and methods in the analysis of power system oscillations and design of PSSs in the multi-machine power system. For t

Multi-machine Power Systems Installed with VSC-Based Stabilizers,n Fig. .. The shunt VSC can be connected to an energy storage system (ESS), a HVDC, or a static renewable power station, such as a photovoltaic (PV) or fuel cell (FC) power station. It can operate alone as a VSC-based FACTS device, STATCOM (see Sect. .).
