【摘要】 针对油田电网负荷特点和运行特性,建立了抽油机的数学模型,并根据油田配电网多分支辐射式单向供电的接线方式以及负荷分散性大、功率因数低、电压压降大的特点,采用了随器补偿和分散补偿相结合的方式,通过前推回代法计算潮流,以灵敏度分析确定补偿地点和补偿容量.仿真结果表明了该方法的有效性.更多还原

【Abstract】 Aiming at the load characteristics and operation speciality of distribution network in oil field,sets up the mathematical model of oil-pumping machine,according to the more-embranchment,radiate and unilateral power-supply connection mode of distribution network in oil field,as well as the characteristics that dispersiveness of load is large,power factor is low,terminal voltage drop is huge,adopts the means that combining the transformer compensation and disperse compensation,calculates the tide with forward and backward substitution method,analyzes and ascertains the compensation point and compensation capacity by sensitivity.Simulation results show the validity of this method.更多还原
