基于J2EE架构的分布式电网故障计算系统
|
摘要
随着我国电力事业的快速发展，电网大规模扩建，使各级电网节点数量不断增加，这大大增加了继电保护整定计算量，而故障计算占其绝对的比例，因此基于单机版和C／S模式的电网故障计算软件已经或即将不能满足电网扩建的要求，必须让多台连网的计算机同时进行故障计算。再加上从上个世纪九十年代以来，我国电力行业相继建立了自己的内部网并与因特网相联系起来，这给电网故障的分布式计算提供了必要的网络条件。
基于以上原因，本文作者在吕飞鹏博士的指导下，提出了基于分布式电网故障计算的设想。使多用户能够同时通过浏览器实现远程故障计算，同时系统具有良好的扩展性，能够与整定计算软件、定值管理软件以及其它系统实现良好的集成。
形成电网正、零序节点阻抗矩阵在故障计算中占有绝对比重。本文为了从算法上提高故障计算的速度，在完全计及支路互感的前提下，利用节点注入电流与支路电流以及支路电流与节点电压的关系，提出了一种能够统一处理互感和无互感线路、快速形成大规模电网节点阻抗矩阵的新方法。
The amount of relay protection setting is increased along with rapid deveJopment of power network and increase of the amount of power network node. So the stand-alone computer, G/S modes have not been satisfied the need of developing power system. It is necessary that let the related computers to work out the fault of power system in time. And then the intranet has been constituted in power system followed technology revolution of net originated from 1990. It provided the necessary facility to realize the Web-based distributed fault computation system.
The author put forward the conception of distributed fault computation system from the request of user. The system can not only compute the fault of power network by many clients but it can well integrate relay protection setting system and distributed management information of values.
A new viewpoint to observe the relation of bus voltage, bus current injection and branch current of the network considering branch mutual inductance has been provided in this paper. The process of building the Z-Matrix of a large-scale power network is set forth in particular in this paper. And the method is employed in the fault computation system successfully.
