根据输油工艺要求,输油泵站主泵常以单机组、双机组和三机组运行。鉴于70年代我国所建的输油泵站变电所多采用两台电力变压器供电。为了使电力变压器处在最佳运行状态,本文以生产运行数据为基础,分析了双机组、三机组运行时电力变压器不同的供电方式,计算其耗电量,从而找出最佳运行方式,为长输管道节能增加了效益。 According to the requirements of oil transportation, the main pump of oil pumping station is often operated by single unit, double unit and triple unit. In view of the 70’s oil pump station built by our country to use two more power transformer substations. In order to make the power transformer in the best operating condition, this paper analyzes the different power supply modes of the power transformer in the operation of the two units and three units based on the production and operation data, calculates the power consumption, and finds out the best operation mode Energy-saving long-distance pipeline increased efficiency.
