提出了一种基于直流潮流的无功补偿自动配置方法。该方法针对已安排好的网架结构及参数、发电出力和负荷计算直流潮流，依据支路有功潮流分布估算节点理想无功补偿量；考虑并联电容电抗器的实际装设情况将无功补偿量转移到具有无功补偿能力的节点上；根据实际无功装置的单组容量和组数进行离散化，最终获得符合实际的无功补偿配置方案。该方法适用于方式安排中初始潮流方式的生成，为制定合理的运行方式提供帮助。基于实际电网的测试算例表明，该方法正确有效，简单实用，能够制定合理的初始无功补偿配置方案。

A DC power flow based automatic configuration of reactive power compensators is proposed. Based on the planned frame structure and parameters power grid, output of generating units and load the DC power flow is calculated, and according to the distribution of the active power flow in branches the amount of ideal reactive power compensation is estimated; considering actual installation of shunt capacitors and reactors the amount of reactive compensation is transferred to the nodes with the capability of reactive compensation;then the ideal compensation amount is according to the capacity of single-bank of capacitor and the number of banks the ideal compensation amount is discretized, and finally a configuration scheme of reactive power compensators is obtained. The proposed method is suitable for the formation of the initial power flow in the operation mode arrangement to offer the help for the drafting of reasonable operation modes. Results of the actual power grid based testing cases show that the proposed method is correct, effective, simple and convenient to use, and using this method a reasonable initial configuration scheme of reactive power compensators can be achieved.
