一、问题的提出在多级提水灌溉的情况下,各级泵站不仅担负着向本级供水浇地,而且同时还担负向上一级泵站供水的双重任务。因此,各级泵站电表所记录的提水耕电量,在通常情况下并不是各级泵站本级浇地的实际耗电量。为了计算各级电灌站本级浇地实际用电量,以前大多采用按地形扬程高低浇地面积多少 First, the issue raised In the case of multi-level water diversion, pumping stations at all levels not only responsible for the level of water supply to irrigated, but also bear the double duty to the water level of a pump station. Therefore, the water pumping power recorded by meter meters at all levels is not usually the actual power consumption of the pumping station at the pumping station at all levels. In order to calculate the actual use of electricity at all levels of irrigation stations at this level irrigated, mostly by the top of the terrain lift the amount of land area
