Oil field distribution network motor cluster pulsating power complementation and grid loss energy-saving optimization method

The power flow of distribution network of oilfield is affected by the period pulsation of pumping unit and shows the characteristic of random fluctuation. The line loss of the distribution network can be effectively reduced by adopting the method of pulsating power complementary control to the motor clusters. Pulsating power complementary principles for oilfield distribution network are proposed and analyzed. The theoretical simulation model of oilfield power distribution network is built. The simulation results show that the line loss of distribution network can be reduced by 38% by using the method of pulsating power complementary of motor cluster. Moreover, many problems are resolved effectively, such as voltage fluctuation of oilfield distribution network, low power supply quality, etc.
