| Abstract: | The excitation system based on full-controlled-devices has two channels to provide damping for power system: excitation control and reactive power injection.This paper focus on the capability of reactive power injection improves system damping characteristic.Typical topology of the excitation system based on voltage source converter(VSC) is introduced,and its equivalent model is deduced.Then the Philips-Heffron model of a single-machine infinite-bus power system installed with the excitation system based on full-controlled-devices is established.The phase compensation method is applied to design the reactive power injection controller.Simulation results show that the excitation system based on full-controlled-devices can damp low frequency oscillations and maintain system stability more effectively than conventional excitation system. |
