摘要
同调发电机聚合参数的优化对等值后系统的动态特性有重要影响.目前频域拟合法是发电机参数聚合常用的方法,该方法是通过目标函数确定出等值发电机的多个参数,这些参数的准确性直接关系到等值的效果.对于目标函数中多个变量的寻优,为了避免局部寻优的结果,可以考虑将改进蚁群算法的模型应用于基于频域拟合的发电机动态参数聚合中.通过新英格兰39节点系统实际算例优化结果和动态仿真结果比较分析,验证了该方法在发电机参数聚合中的有效性.
The optimization of coherent generators＇ parameters has an important impact on the dynamic characteristic of the powersystem which was equivalented.Presently,the fitting method in frequency-domain is in common use;this method need determine multiple parameters of equivalent generator by object function and the accuracy of this parameters impacts the equivalentce effect directly.For optimizing the multiple variable of the object function the improved algorithm model is presented and is uesd to aggregate generators＇ parameters to avoid local extremum.The validity of this method is verified by the results of optimization and Dynamic Simulation for the IEEE New England Test System with10-machine-39-bus.
