基于实测相频特性的电力系统稳定器参数设计
Design of Parameters for Power System Stabilizer Based on Measured Phase Frequency Characteristics
摘要
Abstract
Power system stabilizer (PSS) is one of the most effective measures to damp the low frequency oscillation in the power system,and its parameter setting is comparatively complex and difficult.According to the measured uncompensated phase frequency characteristics of the excitation system,and based on the objective function of minimizing the sum of absolute value of the difference between the square of compensation phase required by excitation system and the square of PSS phase,this paper uses Levenberg-Marquardt optimization algorithm to obtain the PSS lead/lag link parameters.Based on the measured phase frequency characteristics,the simulation result shows that the proposed method can effectively improve the damping characteristics in certain mode and restrain the low frequency oscillation in the power system.The optimization of this paper mainly helps the PSS provide the excitation system with enough phase compensation,and it is noted that Levenberg-Marquardt optimization algorithm is applied to this area for the first time.关键词
