针对变电站综合自动化系统在线监测需求,阐述了设备健康管理的重要性。分析了影响传统综自变电所二次系统健康状态的各种因素,包括运行环境、设备性能以及站控网络等。构建了在线监测指标体系的三种获取途径:设备运行条件类指标通过安装传感器获取;设备性能类指标通过读取设备自检信息获取;智能设备网络状态类指标通过通讯监听分析的方式获取。探讨了实施这些指标在线监测所需的数据采集技术和状态评估方法,研究成果已在德清供电公司变电站得到实施和验证。
Aimed at the demand of on-line monitoring of substation integrated automation system, the importance of equipment health management is expounded. The factors influencing the health status of the secondary system of the traditional integrated substation are analyzed, including the operating environment, equipment performance and station control network. Three ways of acquiring online monitoring index system are established: indicators of equipment operating conditions are obtained through installation of sensors; indicators of equipment performance are obtained through reading self-test information of equipment; and indicators of network status of intelligent equipment are obtained through communication monitoring analysis. The data acquisition techniques and state evaluation methods for on-line monitoring of these indicators are discussed. The research results have been implemented and verified in the substation of Deqing Power Supply Company.
