牵引变压器经济运行监测系统设计

Design of the Monitoring System for Economic Operation of Traction Transformer

针对电气化铁路普速路网上各类列车混和开行,导致牵引变电所牵引变压器的过负荷保护频繁动作的问题,应用组态软件特性,就牵引变压器经济运行下的功率损耗展开组态设计。构造了面向对象的工程框架,通过定义数据对象、制作图形界面等,实现了对指标的实时/历史数据与曲线的获取,组态配置出高性能、高可靠性、高度专业化的牵引变压器监测系统。仿真结果表明,所设计的牵引变压器经济运行,监测系统满足牵引变压器经济运行状态评估要求的数据和流程的可视化,特别适用于牵引变压器保护监控的数字化改造。

In electrified railway ＋ normal speed road network system~ mixed operation of all kinds of trains may lead to frequent action of the overload protection of traction transformer in traction substation. By applying the features of configuration software, the configuration design is carried out for power loss of the traction transformer under economic operation. The object-oriented engineering framework is constructed, through defining data object, making the graphic interface, the real time / historical data and curves of the indexes are obtained, thus the high performance, high reliabilityI highly specialized traction transformer monitoring system is configured. The results of simulation show that the monitoring system designed satisfies the requirement of visualization of the data and process for economic operation state evaluation, it is suitable for digitized retrofit of the protection and monitoring for traction transformer.
