泵站变压器经济运行分析及实时监

针对目前泵站变压器经济运行可操作性差，节能效果不明显等缺点，从分析泵站变压器经济运行的特点入手，在详细讨论了泵站变压器经济运行原理及判定原则的基础上，设计开发了基于Profibus-DP现场总线的变压器经济运行实时监控系统。该系统通过实时采集变压器现场数据，经分析计算和判断，选取变压器经济运行方式，自动投切变压器。实际试运行表明：系统具有计算判断准确，投切可靠，节能效果明显等特点，很好地满足了泵站安全、高效、节能的运行要求。

Economic Operation Analysis and Real-Time Monitoring System Design of Transformer for Pumping Station

The current transformers in pumping station have the shortcomings of difficult to operate and waste of energy.In order to overcome these shortcomings,an economic operation real time monitoring system for transformer of pumping station is designed based on Profibus DP field bus starting from the analysis of the economic operation characteristics according to the economic operation principle and identification criteria.The system can real time gather data,select the economic operation mode,and automatic switch the transformer through analysis and identification.Practical test show that the system has the merits of correct identification,reliable switching and energy saving,so it can meet the requirements of safe,high efficient and energy saving operation of pumping station.
