A PSS(power system stabilizer) is a device to protect a power system by suppressing the low frequency vibration
in a power system or generator. It monitors the vibration of a power system and supplies a stabilization signal to an excitation system. By improving the stability margin of a system, you can reduce the facility investment costs required for reinforcing a system of the transmission line and the increased amount of power generation for high output continuous operation of a power generator.
