| 摘 要： | 负荷模型对电力系统综合计算分析影响很大,负荷模型考虑不恰当,会成为电网运行控制的潜在危险。基于自动故障拟合法的原理,分析了自动故障拟合法、节点法辨识的参数仿真曲线与实测曲线的拟合效果,最终通过对7种方案进行自动辨识,给出了宁夏电网不同类型负荷的模型参数。结果表明:自动故障拟合法拟合效果接近真实值,能很好地模拟实际系统的动态响应,其在大电网下辨识得到的参数是可靠、正确的。

| Abstract: | The load model has a great influence on comprehensive calculation analysis of power sys?tem, if considering impertinence, it has become the potential risks of operation control in power grid.The paper based on automatic fault fitting principle, analyzes the automatic fault fitting methld, andthe fitting effect of the parameters simulating curve of node identifying and measured curve, by auto?matic identifying of 7 schemes, puts forward the different type of load model parameters of NingxiaPower Grid. The result shows that the fitting effect of automatic fault fitting methld approachs real val?ue, can primely simulating the dynamic response of real system, the identifying parameters gainedingfrom the big power grid are credible and correct. |
