国外核电机组参与系统调峰情况分析

我国核电装机比例在不断地提升,研究国外核电机组参与系统调峰情况可为我国未来核电机组的发展和运行提供借鉴。分析了目前世界上核电发展较快的国家核电机组装机情况以及参与系统调峰的运行情况,指出核电机组是否需要参与系统调峰运行是由所在电力系统的电源结构等诸多特性决定的。以法国为例,作为世界上核电装机比重最大的国家,由于其电力系统的调峰手段较为有限,核电机组需直接参与电网的负荷跟踪运行。而其他一些国家,如美国、加拿大、日本、韩国等,其核电装机比例相对法国较低,调峰电源配置较为充足,经济补偿机制较为完善,核电机组一般不参与电网负荷跟踪。

Overview of Foreign Nuclear Power Plants in LoadFollowing

As the proportion of nuclear power in China is becoming greater constantly, it can provide reference to study the load following of foreign nuclear power plants for nuclear power units developing and operating. Analyzing the development of nuclear power plants and the loadfollowing of nuclear units in developed countries worldwide, this paper points out that whether the nuclear units are necessary to involve in load following depends on the characteristics of power sources of the electric power system in these countries. French, as an example, has the largest proportion of nuclear power in the world, and its nuclear power units must take part in load following as its electric power system lacks loadfollowing means other than nuclear power. But in the other countries such as the USA, Canada, Japan or Korea, the proportion of nuclear power is smaller and there are enough power sources for load following with relatively complete economic compensation mechanism, the nuclear power units in these countries are commonly out of load following.
