0.4kV配电网无功补偿多点配置研究

针对低压配电网无功补偿问题,建立了以最小网损为目标函数的无功补偿优化模型,运用改进内点法对优化模型进行求解.并对在配变低压侧根部一点配置补偿装置无法解决的低压配电网网损等现象,提出了在配变低压侧三相线路上多点分布配置无功补偿装置的优化方式,先以所有负荷节点做为待补偿点用改进内点法对模型进行求解,得到理想配置方案后,考虑到补偿的经济性及检修方便等因素,选定几个最终补偿点进行无功补偿装置配置.对实际的低压配电网进行了分析计算验证方法的可行性和实用性.

Research on Reactive Power Compensation Multi-point Configuration of 0.4kV Distribution Network

Aiming at the problem of reactive power compensation in low voltage distribution network,a reactive power compensation optimization model with the minimum net loss as the objective function is established,and the improved interior model is used to solve the optimization model in the process of optimization.And in view of the allocation of compensation device in the distribution of low-pressure side of the root point can not solve the low-voltage distribution network loss and so on,the optimization method of reactive power compensation device with multi-point distribution on the low-voltage side of the distribution transformer is proposed,the model is solved by using the improved interior point method with all the load nodes as the compensation points,taking into account the economy of compensation and easy maintenance and other factors,several final compensation points for reactive power compensation device configuration are selected after obtaining the ideal configuration program.The feasibility and practicability of the method are analyzed and verified by the actual low-voltage distribution network.
