Condition Monitoring System for Circuit Breaker Based on Substation Automation System
Condition monitoring of circuit breaker ispreference for cost saving in power utilities.However,extensive condition monitoring of circuit breaker is ahard task considering its tremendous number.Circuitbreaker time,which is composed of opening time andarcing time,as well as its variation trends,can be usedas an index to represent condition of mechanical anddielectric component of circuit breaker.Since thedigital relay and digital fault recorder that can recorddynamic process of circuit breaker operation,it isespecially attractive to extract this data for circuitbreaker information without hardware investment.Inorder to deduce circuit breaker time with transientdata logged in substation automation system,asubstation automation information managementsystem is developed in this paper.The transient datafollows transient data transformation standard(COMTRADE)is concentrated in controlling center.The information management svstem parses thecomposition and format of the logged data accordingCOMTRADE,hence calculate and visualize the circuitbreaker time and its variation trends.
