【摘要】：随着负荷和网架的发展,近年来负荷中心的1 000 MW级机组电力就近消纳的趋势越来越明显,但1 000 MW级接入220 kV电网目前还处于探索阶段,缺乏实际运行经验。研究1 000 MW级机组接入220 kV电网的积极效用和对电网运行的影响,寻找限制接入的主要因素;将制约因素转换为对系统短路容量和机组接入距离的要求,在同一个坐标系内利用图解法进行分析。结果较为直观地体现了各因素的不同影响效力。以上海某220 kV电网为例,提出开展1 000 MW级机组接入220 kV电网试点的设想,得出了在某些典型供电分区内1 000 MW机组接入220 kV电网的主要技术条件。
[Abstract]:With the development of load and grid, in recent years, it is more and more obvious that the power of 1 000 MW units in the load center is getting closer and lower. However, it is still in the exploration stage for 1 000 MW to connect to 220 kV power network, and it is lack of practical operation experience. This paper studies the positive utility of 1 000 MW units connecting to 220 kV power network and its influence on the operation of the network, finds out the main factors restricting the access, and converts the restrictive factors into the requirements for the short circuit capacity of the system and the access distance of the units. In the same coordinate system, the graphic method is used to analyze. Results the effects of different factors were reflected intuitively. Taking a 220 kV power network in Shanghai as an example, this paper puts forward a tentative idea of connecting 1 000 MW units to 220 kV power network, and obtains the main technical conditions for 1 000 MW units to connect to 220 kV power network in some typical power supply zones.
