Abstract

Condition monitoring of circuit breaker is preference for cost saving in power utilities. However, extensive condition monitoring of circuit breaker is a hard task considering its tremendous number. Circuit breaker time, which is composed of opening time and arcing time, as well as its variation trends, can be used as an index to represent condition of mechanical and dielectric component of circuit breaker. Since the digital relay and digital fault recorder that can record dynamic process of circuit breaker operation, it is especially attractive to extract this data for circuit breaker information without hardware investment. In order to deduce circuit breaker time with transient data logged in substation automation system, a substation automation information management system is developed in this paper. The transient data follows transient data transformation standard (COMTRADE) is concentrated in controlling center. The information management system parses the composition and format of the logged data according COMTRADE, hence calculate and visualize the circuit breaker time and its variation trends

基于变电站自动化系统的断路器状态监测系统

断路器状态监测是电力企业节约成本的首选手段。然而，由于断路器数量庞大，对其进行广泛的状态监测是一项艰巨的任务。断路器时间由开断时间和起弧时间组成，其变化趋势可以作为表征断路器机械和介电部件状态的指标。由于数字继电器和数字故障记录仪可以记录断路器运行的动态过程，因此在不投入硬件的情况下提取断路器信息的数据尤其具有吸引力。为了利用变电站自动化系统中记录的暂态数据推断断路器时间，本文开发了变电站自动化信息管理系统。暂态数据按照暂态数据转换标准(COMTRADE)集中在控制中心。信息管理系统根据COMTRADE对记录数据的组成和格式进行解析，从而计算和可视化断路器时间及其变化趋势
