【摘要】 在总的无功补偿容量一定的情况下,补偿容量在各补偿端口的不同分配,负序电流存在一个最低点,即固定并联电容补偿在各补偿端口的不同分配存在一个最佳容量配置点.建立固定补偿容量优化配置的数学模型,采用广义拉格朗日乘子法对补偿容量的配置进行优化设计.并用牵引变电所实测数据验证了所给方法的有效性.更多还原

【Abstract】 In the reactive power compensation of traction substation with given compensation capacity,there is a minimum negative sequence current for different distribution of compensation capacity at the compensation ports.In order to calculate the optimal configuration of the fixed compensation with minimum negative sequence current,the mathematic model of optimal configuration of the fixed compensation is established,and the configuration of compensation capacity is optimized using generalized Lagrange Method of multipliers.On site measurements in traction substation shows effectiveness of the proposed approach.更多还原
