摘要
国家实施西电东送规划中,建设了天广直流输电系统工程,与广东电网联网运行,形成了中国第一个交直流并联的联网运行系统,大大加强了电网结构。这样,在提高西电送广东电网的输送能力的同时,对广东电网有所影响,尤其对广东北部电网影响较大,为此,应用实例,具体分析各种影响及其产生的原因、存在的问题及其对策,以期在实际的运行中,引起必要的重视,进一步确保电网的安全稳定运行。
As a part of the project of electricity transmission from West China to East China, TianGuang DC transmission system is constructed and interconnected with Guangdong (GD) power grid to form the first AC & DC paralleled system in China, which greatly improves the grid configuration and the capacity of electricity transmission to GD. However, the system has some influences on GDs power network, especially on its north part. Therefore, a case study is conducted to analyze these influences and their causes, present problems and countermeasures, thus evoking attention in operation to further ensure the safety and stability of power grid.
