粒子群优化算法及其在发电机组调速系统参数辨识中的应用

准确可靠的发电机组调速系统模型参数对于电力系统稳定性分析非常重要,由于利用常规辨识方法(如最小二乘法)进行模型参数辨识时对试验条件要求较为苛刻,且很难对调速系统中大量存在的非线性环节参数进行辨识.本研究将目前正处于研究热点的粒子群算法引入发电机组调速系统模型参数的辨识过程研究,结果表明,利用粒子群理论进行模型参数辨识时...

Particle Colony Algorithm and Its Application in Discriminating Parameters of a Speed Regulation System of a Generator Unit

Accurate and reliable model parameters of a speed regulation system of a generator unit are most important for analyzing the stability of its electric power system.As the requirements for test conditions are relatively rigorous when the conventional discrimination methods(such as least square method) are used to discriminate the parameters of a model,so it is very difficult to identify the parameters existing in a large quantity of a nonlinear link of a speed regulation system.The authors introduced a parti...
