摘要:

电网运行过程中,每天都可能有新建变电站对继电保护装置做入网试验,这些试验数据和真实故障发生时一样,将保护动作相关数据上送到调度端故障信息系统中,并生成电网故障报告。对于调度运行人员来说,只需要关注真实故障产生的电网故障报告,由现场试验产生的电网故障报告需要故障信息系统做有效识别并过滤排除。因此如何通过有效手段识别这些检修试验电网故障报告和真实故障报告数据,尽量避免误推给调度人员就显得非常重要。根据现场运行经验提出了4种比较实用的排除试验数据的方法,即检修标记判断方法、相邻间隔信息判断方法、同间隔信息判断法和一次设备信息辅助判断法,并以这些思路开发的故障报告整理软件在某电网公司应用。工程实践表明,该软件的运用大大提升了电网故障报告识别准确率。

Abstract:

During the operation of the power grid, network accessing tests may be made on protective relay devices of new substations everyday. The test data of the protective relay devices will be sent to the fault information system of dispatcher and generate fault report, as they act in a real fault. For dispatching operators, only the real fault report will be notified and those fault reports generated by field tests need to be effectively screened and filtered by fault information system. Therefore, it is very important to identify these fault reports by effective approaches instead of by dispatch operators. Four practical methods for eliminating test data which are judging by maintenance mark, judging by adjacent interval information, judging by information in the same interval and judging by primary auxiliary information, are put forward according to the field operation experience.The software developed upon these judging methods has been applied in a  electric power dispatching company.Engineering practice shows that the power grid fault report recognition accuracy is greatly enhanced by the software.
