This paper proposes a control plan for a long distance frequency variable water supply sgstm with unstable water pressure and defines a kind of self adaptive control algorithm H c=H st +kQ 2as well as discusses the parameters H st and k. This system has successfully solved the problem concerning the deviation of the working point from the characteristic curve of a pipeline in a long distence water supply pumping system. Thus it not only realizes the normalization of the unstable running water pressure for bouseholds at far ends during the peak consumption, but also decreases the tonnage energy consumption of water.
