| 摘要: |
| 针对配电网负荷多变的特点,提出采用电容器对10kV配电网进行无功补偿时,采用分支线路末端配电变压器低压侧和主馈线相结合的优化补偿方式。以系统有功网损、电容器的安置费用加权最小为目标函数。根据配电网辐射状树形分布特征,首先在分支线路末端以提高线路功率因数确定电容器的补偿容量及其类型,然后在主馈线上依无功负荷的分布情况再确定电容器补偿的最佳位置和容量。潮流计算采用配电网广泛使用的前推回代法。最后,以实际电网为例,说明了该算法的可行性和优越性。 |

| Abstract: |
| A var compensation scheme,which considers both main feeder and transformer low-voltage side of branch lines,is proposed for 10 kV distribution network with capacitors.The objective function is to make minimum the sum of power loss and capacitor installation cost with their weights.Considering the radial structure of distribution network,the capacity and type of capacitor at end of branches are decided first for increasing the line power factor,and then the optimal position and capacity on main feeder are decided according to the var distribution.The forward-backward sweep method is adopted in power flow calculation.Practice in an actual power network has proved its feasibility and superiority. |
