A principle and method for monitoring generator stability by using rotor position detector and generator power angle rotation speed measuring device and improving the static stability of generator with power speed stabilizer (GPSS) are introduced. The experimental results of single phase grounding dynamic mode show that the stability criterion of power angle is intuitive. The GPSS can shorten the recovery time and improve the static stability of the generator. This method provides a feasible solution for the monitoring and control of generator and grid stability.
