电力调度中的网架拓扑及多岛连接设备识别

The Network Frame Topology and the Judgement of Connecting Equipments Between Islands in the Electrical Dispatching System

在电力系统调度中,电网事故、开关刀闸的错误状态等会引起电网在拓扑结构上呈现分裂运行状态。本文提出了电力网架拓扑的概念、模型和方法。在此基础上,提出了识别多电气岛之间连接设备的方法。该方法结合网架拓扑的结果及当前电网的运行状态,划分电气—网架岛,自动定位系统解列点的位置。实践证明该处理方法快速、准确、有效。

In the dispatching of power system, because of the accident of power network and the wrong status of breaker and switch, the power system appears to run in the split state. This paper presents the concept of power network frame topology, it's model and method. Based on the network frame topology, the paper presents the method of judging the connecting equipments between electrical islands. Combined with the result of network frame topology and the state of power network, the method divided the power network into electrical-network frame islands and locate the split point in the system automatically. Practice shows it fast, veracious and effective.
