Characteristic Analysis of Power System Stabilizer with Accelerated Power Under Deep Phase Modulation of Generator
A power System Stabilizer(PSS)with accelerated power may cause problems such as the low frequency and oscillation of power due to large calculation errors during the deep peak modulation of the engine.In order to solve these problems,this paper describes how to analyze the stability of the system,and verifies the rationality of the system analysis with the help of simulation tests.Specifically,the method of calculating the rotation rate by elec-tric gas through the excitation device is adopted.Through solving,the sensitivity analysis of the rotation rate under active and reactive state is obtained,and the accuracy of the on-site theoretical analysis is verified through this analysis.It has a certain reference value for the study of system stability.
