变电站仿真培训系统中的发电机模型

Generator Model for Substation Simulation Training System

在变电站仿真培训系统的模型中计及发电机的动态特性,对提高仿真的逼真性具有重要的积极意义,以一次潮流的计算结果确定发电机动态方程的初始状态,在仿真运行的每个周期内只需计算机网接口参数,求解节点电压方程,即可得到电力网络的状态参数。这种方法避免了动态潮流法计算时间长、收敛性不能保证等缺点。经实践证明该方法是可行的。

Concerning dynanic characteristic in simulation model is necessary for the increase of the reality of substation simulation training system. Using power flow once to determine the generator＇s initial stage, it is found that power network parameters could be got in every simulation cycle by calculating generator-network interface and resolving node voltage equation. By this way, the disadvantages in dynamic power flow method of costing more computer time are prevented and the convergence could not being always got, etc. It is be proved working well by practive.
