摘要
核电站变压器冷却监控系统由于复杂的回路接线导致故障频发,其运行可靠性及控制精确度有待进一步提升。围绕该问题,以WAGO-PFC200XTR可编程控制器为平台研发了一种新型变压器冷却监控系统。首先,设计了系统的整体功能架构组成,并进一步设计了可编程控制器接线及主程序流程,此外提出了基于变压器顶层油液温差和温差变化率的温度模糊控制策略,最后展示了监控系统的应用界面。试运行结果表明,该系统操控方便、可靠性高、控制精确,有效降低了变压器运维成本,具有一定工程应用价值。
The fault frequency of cooling monitoring system of nuclear power station transformer is very high due to complex loop wiring,the operation reliability and the control precision need to be furhter improved.In order to solve this problem,a new cooling monitoring system of transformer is developed based on WAGO programmable logic controller.Firstly,the overall functional architecture of monitoring system is designed,then the looping wiring and the main program flow of programmable logic controller are further designed.In addition,the temperature fussy control strategy based on oil temperature difference and temperature change rate is proposed.Finally,the application interface of monitoring system are displayed.The test operation result shows that this system is easy to control,has high reliability and control precision,and could effectively reduce the cost of transformer operation maintenance.Thus,this cooling monitoring system has a certain of application value.
