Abstract: In recent years, the construction of domestic power grid has developed rapidly, under the integrated management mode of dispatching and control, the requirements for the rapidity and accuracy of the power grid fault analysis carried out by the regulation and control center are continuously improved. The voltage level range monitored by the provincial regulation and control organization also sank from 220 kV to 10 kV. The regulation cloud platform can provide full data of power grids above 10 kV, through analysis, it is found that the existing data quality of cloud platform is low, which can not meet the requirements of traditional power grid fault alarm research and judgment technology; the research and judgment technology of equipment trip alarm applicable to the current basic data is studied to improve the alarm accuracy and provide strong support for regulators to monitor the operation of power grid and deal with faults in time.

Keywords: power grid fault; trip research and judgment; alarm; dispatching and control cloud

在調控一体化管理模式下,对于调控中心开展电网故障处置分析的迅速性、准确性要求不断提高,省级调控机构监视电网的电压等级范围,也由原来的220 kV下沉扩大至10 kV主线。传统的电网设备跳闸研判技术,基于遥信遥测+模型拓扑,研判准确率高度依赖电网数据建模的完善程度。调控云平台相比原有旧平台,虽然汇集数据范围更大[1],能够满足基础数据采样覆盖面的要求,如图1所示,但从平台现有建设来看,数据质量较差、模型建设不完善,传统研判技术在该平台的准确率较低。本文基于行业经验,研究基于调控云平台数据现状的电网设备跳闸研判新技术,该技术已经在国内一些地区电网调度领域得到应用,为调控人员监视电网运行情况提供有力支撑。

1  省级电网调控云系统建设

从2018年开始,国家电网系统内调控机构逐步开展调控云平台的建设工作。……
