【摘要】：特高压电网是坚强智能电网的基础。在分析1 000 kV输电系统数学模型及运行特性的基础上,搭建拟建雅安—武汉1 000 kV交流特高压输变电工程仿真模型,以重庆电网为研究背景,分别在特高压交流工程投入运行和不投入运行2种情况下仿真分析重庆电网不同运行方式、不同电源结构时的运行稳定性情况。结果表明,拟建雅安—武汉1 000 kV特高压交流输变电工程能实现川西水电的跨区域、远距离、大容量、低损耗、高效率传输,有效缓解川西弃水现象,提高川渝间电力交换能力,提升重庆电网运行的安全稳定性,然而为进一步发挥特高压输电的优越性需对现有网架进行升级改造。
[Abstract]:UHV power grid is the foundation of strong smart grid. On the basis of analyzing the mathematical model and operation characteristics of 1 000 kV transmission system, the simulation model of Ya'an-Wuhan 1 000 kV AC UHV transmission and transformation project is built, which is based on Chongqing Power Grid. In the case of UHV AC project put into operation and not put into operation, the operation stability of Chongqing power grid under different operation modes and different power supply structures is simulated and analyzed. The results show that the proposed Ya-Wuhan 1 000 kV UHV AC transmission and transformation project can realize long-distance, large capacity, low loss and high efficiency transmission of west Sichuan hydropower, and effectively alleviate the phenomenon of water abandonment in western Sichuan. In order to improve the power exchange capacity between Sichuan and Chongqing and to enhance the safety and stability of Chongqing power grid operation, however, in order to further exert the superiority of UHV transmission, it is necessary to upgrade and transform the existing grid.
