资料介绍

在外网信息完全未知的情况下,提出了基于内网Ward等值电路的外网静态等值方法.现有的基于内网信息估计外网等值参数的方法仅依赖于边界节点处的功率方程约束关系,没有充分利用内网其他相关的量测信息.首先基于内网的实测信息得到其常规Ward等值电路,然后建立外网等值参数的量测方程,以此求解外网等值模型参数.通过引进内网常规Ward等值电路,增加了对外网等值参数的约束,使参数估计值更加准确合理.IEEE-39节点系统的仿真结果验证了该方法的有效性.

In the case of the external network imformation completely unknown,this paper presents an external network static equivalent on the basis of internal general Ward equivalent circuit. Existing external network equivalent parameter estimated method based on the internal network information, which only rely on power equation constraint relation of the boundary nodes, does not use rest measured information of internal network adequately. First, this paper obtain internal network's general Ward equivalent circuit based of its measured in- formation,then establish measurement equation of external equivalent parameter and solve it. The introduction of internal general Ward equivalent circuit, enhance the constraint to externa...
