全世界电力系统共同面临的现实是:经济的发展要求能源资源在更大的范围内优化配置,客观上要求电网的规模不断扩大,然而任何一个客观事物的存在和发展都具有两重性。大电网的优势是显而易见的,能够促进能源资源的合理利用,实现输电的规模经济效益,提高电能质量和电网的安全稳定水平。但随着电网的互联和电网覆盖范围的扩大,大电网一旦发生事故而且不能迅速消除时,很可能导致稳定破坏和不可控的连锁反应,造成大范围、长时间的停电,对社会的政治稳定和经济安全造成严重影响,这是其他行业的事故无法比拟的。正是由于这对矛盾的存在,才促使电力技术和管理体制的不断创新。在当前新的电力体制下,尽快建立适应新体制的电网安全运行机制是当务之急。下面就结合南方电网的实际谈一谈对建立和完善电网安全运行及应急机制的建议。
The reality that power systems in the world face together is that economic development requires that energy resources be optimally deployed in a larger scope, and objectively requires that the size of the power grid be continuously expanded. However, the existence and development of any objective objective have the dual nature. The advantages of large power grids are obvious, which can promote the rational utilization of energy resources, realize the economies of scale of transmission, and improve the power quality and the safety and stability of power grids. However, with the interconnection of power grids and the expansion of power grid coverage, once an accident occurs in a large power grid and can not be quickly eliminated, it is likely to cause stabalization and uncontrollable chain reactions, causing widespread and prolonged power outages and political stability to society And economic security have a serious impact, which is unmatched by accidents in other industries. It is precisely because of the existence of these contradictions that the continuous innovation of power technology and management system has been promoted. Under the current new power system, it is imperative to set up a safe operation mechanism of power grid to adapt to the new system as soon as possible. The following combination of the actual situation of China Southern Power Grid to establish and improve the safe operation of power grids and emergency response mechanism.
