摘要
提出一种同步电机在线参数辨识新方法:同步发电机状态空间离散模型的非线性规划辨识方法。该方法利用在线测量的同步发电机动态过程的离散采样数据进行计算,直接得出同步电机的待求参数。数值仿真表明:此算法计算速度快,辨识精度高,数值稳定性好。在一台MTF-5-1500型模拟同步发电机组上进行了所研制的硬、软件动模试验,结果表明:新方法测得的参数更符合实际工况。
This paper presents a new method of parameter recognition of synchronous machine, a method of non linear programming based on state space discrete model. By this method, calculation can be carried out by using discrete sampling data on line measured in sychronous machine dynamic process, and parameters needed can be obtained directly. Data simulation indicates that this algorithm features fast, precise and reliable. The results from hard and soft ware developed and dynamic simulator test on a type MTF 5 1500 simulator sychronous generator shows that parameters measured by this new method better conform with actual operation.
