摘要
本文以基准模型为研究对象,利用特征值分析法对电力系统次同步振荡问题进行了深入的分析,计算得到了次同步振荡的频率和阻尼参数等,进一步用特征值分析法计算了系统的参数的改变对于次同步振荡阻尼的影响,通过仿真验证了特征值分析算法的正确性。
This paper taked the benchmark model as the research object,and used eigenvalue analysis method to analyze the subsynchronous oscillation of power system deeply.The frequency and damping parameters of subsynchronous oscillation were calculated.Furthermore,the eigenvalue analysis method was used to calculate the change of the parameters of the system for the influence of subsynchronous oscillation damping.The correctness of the eigenvalue analysis algorithm was verified by simulation.
