地县级电网全局电压无功优化的研究和软件开发

The Research and Software Development of Voltage and Reactive Power Optimization in Prefectural Power Network

针对地县级电网辐射状的网络结构,将网络划分为小的独立的优化单元,采用将电容器投切和变压器分接头档位的调节进行解耦处理的优化方法,简化了全局电压无功优化问题求解的复杂度;开发出适用于地县级电网的全局电压无功优化软件,该软件同时考虑现场操作的实际要求,对调节效果进行评估,提高了软件的实用性。

The prefectural electric power network has its own characteristics. Because of the radiation characteristic of the network, this paper considers the network as the combination of some small optimization units. The paper simplifies the resolution of the reactive voltage optimization by alternatively solving the adjusting transformer taps and switching capacity banks. At the same time,considering the practical operational requirements,the paper evaluates the regulation effect and improves the practicability of the software.
