摘要(Abstract)：
通过嘉善10kV配电用户负荷特性等实际情况分析,提出10kV配电线路应根据不同(分支)线路的功率因数特征进行无功补偿,确定补偿容量和补偿点选取方法以及补偿自动控制和保护的技术原则,对10kV配电线路并联电容补偿实施结果的经济效益进行了对比分析。
Because load characteristics of users are different,10 kV distribution line should do reactive power compensation based on different(branch)lines of the power factor characteristics.In this paper,the necessity of reactive power compensation is analyzed by the actual situation of 10 kV distribution line.Capacity compensation and compensation-point selection principles,and automatic control and protection technology of reactive power compensation are put forward.At the same time,economic benefits of shunt capacitance compensation in 10 kV distribution line are calculated.
