摘要/Abstract

摘要： 为解决实际电网规划中UPFC示范工程在超高压层面的布点选择与实施问题，首先基于现有工程经验总结提出UPFC的配置原则；之后研究了UPFC“单位容量调控比例系数”概念，即UPFC控制效果与自身容量的比值，并根据可靠性成本/效益分析，对单位容量调控比例系数进行标准化处理；继而综合得出UPFC布点在技术层面的比较方法，同时给出安装地点选择方法的流程；最后针对UPFC在不同场景的应用，提出了相应的系统级控制策略。应用方案研究中，利用2~3年滚动计算数据，在全国范围内选出12处UPFC的安装地点，通过初步比选和仿真分析，发现UPFC在锦苏直流落点近区输电断面、鄂东江南—江北断面两处地点具有较好的调节能力优势。所提方法切实可行，对超高压层面UPFC布点的筛选和示范工程的实施有一定的指导意义。

Abstract: In order to solve the problem of UPFC installation location selection at UHV level in actual grid planning, this paper first summarizes UPFC's configuration principle based on existing engineering experience. After the concept of UPFC "unit capacity control proportionality coefficient" is studied, that is, the ratio of UPFC's control effect to its own capacity. According to the reliability cost/benefit analysis, unit capacity control proportionality coefficient is standardized. Then, we derive the priority expression of UPFC points at the technical level, at the same time, the flow chart of the location selection method is given. Finally, the UPFC system-level control strategy is proposed for different application scenarios. In the study of the application, using 2~3 year rolling calculation data, 12 UPFC installation sites are selected in the whole country. Through simulation analysis and priority calculation, it is found that UPFC has good regulation ability at two locations of Jinjiang direct current arrival point and two sites of Jiangnan-Jiangbei section of eastern Hubei Province. The method proposed in this paper is feasible with certain guiding significance for the UPFC layout screening and demonstration project implementation on UHV level.

Key words: unified power flow controller (UPFC), unit capacity control proportionality coefficient, UHV power grid, evaluation method, system-level control strategy
