摘要
线路输送的无功的大小直接关系到线路的损耗。根据配电线路负荷分布的特点,把负荷分布简化为均匀分布、递增分布、递减分布等几类。通过求线路损耗最小值的方法,得出最佳的补偿容量、补偿位置和线损的降低程度,并结合经济效益分析,说明线路无功补偿装置的有效性和可行性。
The reactive power magnitude of transmission line is directly related to the line loss. According to the characteristic of load distribution in the distribution line, the load distribution is simplified into such types as uniform distribution, increasing distribution, digression distribution and so on. The optimal compensation capacity, compensation position and the reduced degree of the line loss are obtained through calculation of minimum line loss. The effectiveness and feasibility of the line reactive power compensation system are explained in combination with economic efficiency analysis.
