摘要
为满足大庆油田电网调度和信息管理的需要,同时为了避免大庆油田发生由于过负荷连锁故障而导致的大停电造成过大的经济损失,开发了基于GIS的大庆油田电力系统连锁过负荷故障分析系统软件。该软件利用美国ERSI(环境系统研究所)开发的MapObjects组件及C#进行集成二次开发,并进行必要的扩充,完成了如下的功能:大庆电网主接线图的主界面,基态潮流计算,初始故障的求取,开断潮流的计算,连锁故障路径的显示,故障图的分区显示以及故障率的计算等。通过其显示的连锁故障路径,可以清晰地看出易出现连锁故障的线路,为大庆油田的安全可靠供电提出了有益的警示和参考,为避免更大的经济损失提供了依据。结果表明:求出的关键路径是大庆油田电力系统故障率比较高的路径。证明了结果的正确性。
In order to meet the needs of grid dispatching and information management in Daqing oil field, and meanwhile, in order to ensure Daqing oil field against excessive economic losses resulting from massive power failures that caused by cascading failure, this paper has developed a software of GIS based power system cascading failure overload fault analysis system. The software uses Map Objects components that was developed by American ERSI （Environmental Research System and Institute） ; uses C# to integrate secondary development： carries out the necessary expansion, and at last completes the following functions： the main interface of Daqing Grid＇ main wiring diagram, the ground-state power flow calculation, the calculation of initial failure, the breaking power flow calculation, the display of cascading failure fault path, the partition show of the fault map, the calculation of failure rate, etc. Through the path of the cascading failure showed by the software, we can see clearly the line with cascading failure. So we can propose a useful warning and reference for the safety and reliability of electricity supply in Daqing Oil field, and provide a basis for avoiding further economic losses. The results show that the critical path which is found by the software is the path that has the high failure rate in Daqing oil field power system. The correctness of the results is proved.
