基于SCADA系统进行泵效测试的深化应用

Further Application of Pump Efficiency Test Based on SCADA System

针对中国石化湖南长岭-郴州成品油输油管道输油泵人工测试泵效存在临时工况调节难度大、读数存在偏差、运行参数不稳定、数据获取量小且非连续等因素干扰,获取的数据存在稳定性和代表性不足的问题,应用企业区域调控中心对SCADA系统开发的实时泵效测试功能直接采集电气微机综保系统信号数据和泵机组运行参数,在系统中植入泵效测试计算公式,可以便捷准确地进行泵效测试,进而对长岭、汩罗、湘潭和衡阳站机泵进行了具体测试和数据分析,为管输优化运行和节能降耗提供了数据支撑。

Due to the interference factors such as difficult adjustment of temporary working conditions,deviation of readings,unstable operation parameters,small amount and discontinuity of data acquisition in the manual test of pump efficiency in ChanglingChenzhou oil product pipeline of SINOPEC,the problems of poor stability and representativeness exist in the acquired data.By using the SCADA system,the signal data of integrated protection system in the electric microcomputer and the operation parameters of the pump unit are collected directly,and embedding the calculation formula of the pump efficiency test in the system,the pump efficiency test can be carried out conveniently and analyzed accurately,which can provide the data support for the optimal operation of the pipeline transportation and the energy conservation and consumption reduction.
