【摘要】 针对目前110kV变电站无功补偿准则宽泛,确定的无功补偿取值范围较大,不能准确给出补偿方案的现状,提出了一种针对电缆线路的110kV变电站无功补偿方法,即先分析参与无功平衡因素,从中确定相关特征参数,然后建立含有电缆的典型110kV片网模型,使用多参数参与影响方式计算变电站相应的无功补偿比率,并对特征参数的相关度进行分析,从而得到针对电缆线路的110kV变电站无功补偿方法。实例分析表明所提方法能够便捷、有效地给出无功补偿方案,可应用于工程实际。更多还原

【Abstract】 In view of the fact that the current 110 kV substation reactive power compensation criterion is broad,the determined reactive power compensation value range is large,and the current status of the compensation scheme cannot be accurately given.A reactive power compensation method of 110 kV substation for cable lines was proposed.First,the factors involved in reactive power balance were analyzed,and the relevant characteristic parameters were determined.Then,a typical 110 kV mesh model with cable was established,and the corresponding parameters were used to calculate the corresponding substation.The reactive power compensation ratio and the correlation of the characteristic parameters were analyzed to obtain the reactive power compensation method of the 110 kV substation for the cable lines.The example analysis shows that the proposed method can give the reactive power compensation scheme conveniently and effectively,and can be applied to engineering practice.更多还原
