摘要
近年来在华北电网已建和将要建成多个与山东相关的特高压交直流工程,首先介绍了华北—山东电网输电断面的网络演化与发展进程,研究了山东断面演化发展的各个阶段的输电能力,然后详细研究了各个阶段华北—山东交流断面输电能力的影响因素,主要包括元件热稳约束、输电断面静稳极限、受端电压支撑能力和多馈入短路比等,在此基础上提出了提高山东断面输电能力方法并进行了验证。
In recent years, many UHV AC and DC projects associated with Shandong have been or will be built in North China grid. Firstly, evolution and development process of the network of North China-to-Shandong transmission section was presented, and its capacity in all evolution stages was studied in this paper. Secondly, the factors affecting transmission capacity of the cross section in all stage was researched in detail, mainly including component thermal stability constraint, transmission section static stability limit, receiving end voltage support, and multi-infeed short circuit ratio and so on. Based on that, mesures for improving transmission capability of Shandong section were proposed and verified.
