从负荷密度看中国电网互联格局

中国电网互联格局不仅是理论问题，更重要的是中国电网长远发展的战略问题，互联格局的确定，将对具体联网工程的实施和联网方式直到重要的指导作用。有关单位和许多专家对此作了大量的分析研究工作，但到目前为止尚未形成共识。文章试图以一种新的思路对中国电网互联问题作进一步探讨，通过对远景各民网负荷密度的分析，提出了沿京广和京九铁路两侧、贯穿中国南北，包括上前华北、华东、华中、山东、福建和广东电网在内的中国核心电

A CONSIDERATION OF GRID INTERCONNECTION PATTERN IN CHINA IN VIEW OF LOAD INTENSITY

The grid interconnection pattern in China is not only a theoretical problem, but also a strategic problem related to the long term development of the electric power network in China. The determination of the pattern of grid interconnection will play an important guiding role in the realization of actual grid interconnection and in the interconnection pattern. A lot of analysis and research has been done on this question by many experts and organizations in many concerned institutions, but a common understanding has not been reached up to now. This paper intends to further explore the question of power grid interconnection in China with a new perspective. Through the load intensity analysis on each of the future individual power grids, a conception of core power grid in China is put forward, along both sides of the Beijing Guangzhou railway and the Beijing Kowloon railway running through from North to South China, including the current North China, East China, Central China, Shandong, Fujian and Guangdong power networks. It is considered that the condition of forming a strong AC link inside the core power network will be possessed. It is not suitable to form strong links between the core power network and the surrounding networks. To maintain a high level of security and stability of the core power network, many links between the core and the non core network should be avoided.
