A Research On The Parameter Optimization And Field Test Of The Simulation Speed Regulator For The Isolated Network Of Gansu Power Grid

摘要

In view of the problem of non electromechanical mode oscillation in the process of the operation of the N area network in Gansu area, the cause of the accident caused by the improper governor parameter of the main unit in the isolated network is obtained by the fault simulation and field recording. Based on the analysis of PSASP small interference analysis and PSASP-GOV oscillation mode, the hidden trouble of excitation system and speed regulation system of Gansu power network is analyzed, and the recommended parameters of the operation mode of the unit are given. Finally, the measures to improve the stability of the isolated network are given.
