摘　　要：在钻井井场电网中,由于谐波的存在和无功功率的不平衡,增加了电网输电线损耗,降低了井场设备的稳定性和安全性。研究了一种动态治理谐波及补偿无功功率的方法。开发了谐波治理及无功补偿单元,并在原有的电动钻机控制系统模拟实验平台中模拟该单元的运行情况。经分析表明,该方法可有效抑制电网中的谐波,补偿无功功率,具有实际应用价值。Because of the harmonics and the reactive power imbalance,the power transmission loss of the power grid is in-creased,the stability and the security of well site equipment are decreased.A dynamic method which can control the har-monics and compensate the reactive power is researched.During the research,a harmonic control and reactive power com-pensation unit is designed and its operation is simulated in the well field site simulation platform.The analytic results show that the method can restrain the harmonics and compensate the reactive power in the power grid.
