Method and device for calculating coefficient of converting electricity into water for well group

The invention discloses a method for calculating a coefficient of converting electricity into water for a well group, which comprises the following steps of: selecting N water wells which are simultaneously pumping water, sequentially shutting down the first water well to the Nth water well for testing, and recording the water yield of each water well except for shutting down the water wells in each test and the total electricity consumption in each test; an equation set I comprising N equations is established, the electricity-to-water conversion coefficient of each well is calculated, the water yield of the i-th well in the j-th test, the electricity-to-water conversion coefficient of the i-th well and the total electricity consumption of the j-th test are represented, and i and j are 1, 2, 3... N. According to the invention, the water pumping test does not cause great influence on irrigation operation, and the obtained coefficient of water conversion by electricity is high in precision. 本发明公开了井群以电折水系数计算方法，包
