摘要
利用转矩向量分析法对电力系统低频振荡产生的原因,及电力系统稳定器(PSS)对低频振荡抑制作用进行分析。运用Matlab软件Simulink功能对天生桥二级电站#1机组励磁控制系统建立单机无穷大系统分析模型,通过相位补偿特性实验、小扰动实验证明PSS对低频振荡有较好的抑制作用。
The torque vector analysis is used to analyze the reason of Low-frequenly oscillation and the function of power system stabilizator to low-frequeucy oscillation control.Use Matlab simulink to set up the infinite system analysis model,a single machine for No.1 unit excitation control system of Tianshengqiao Hydropower Station Ⅱ.By phase compensation experiments and small perturbation experiments,they show that the power system stabiliztor is of better control action to the low-frequency oscillation.
