摘要潜油电泵在变频驱动时,潜油电机星点处会产生较高的共模电压和高次谐波,严重危害潜油电泵机组井下系统的正常运行。为解决这一问题,设计了一个潜油电泵机组井下变频电压消压器,仿真结果表明:该消压器能有效抑制电动机星点处产生的共模电压与谐波。 Considering that fact that higher common mode voltage and higher harmonics can occur at the star point of submersible motor when submersible pump is driven at variable frequency and this may seriously damage the operation of the downground system of the submersible electric pump unit,a kind of variable-frequency voltage depressor for the underground submersible electric pump unit was designed. Simulation results show that,this voltage depressor designed can effectively suppress the common mode voltage at the star point of the submersible motor and can reduce the negative effects caused by it.
