When a large amount of wind power being integrated into power system, will make system stability deterioration. At present these methods for improving stability are not very economical. This paper is aimed at solving the stability problem of multi-machine wind power integrated system, therefore power system stabilizer (PSS) are installed for synchronous generator(SG), through properly regulating PSS and AVR parameters to observe the stability of various situations. The simulation results show that wind power integrated system with AVR and PSS1A has damping effect, can reduce the oscillation of rotor angle difference, improve voltage stability. SVC with PSS4B and AVR together will have a better damping, the oscillation amplitude has been significantly reduced, so SVC can also improve stability of wind power integrated system, tripping frequently and tripping mistakenly of the corresponding relay protection can be avoided.
