大容量核电机组投运对电网运行的影响

The Impact on Power Grid Operation after the Large Capacity Nuclear Power Generating Unit Putting into Operation

大容量核电机组在电力系统的投运,既提高了系统的裕度,也提高了系统供电的可靠性水平及资源的效益。一方面,较大的机组容量的投切增大了对电网运行的影响;另一方面,由于核电机组的特殊性,机组对电网运行也提出了更严格的要求。文章从各方面对大容量核电机组投运对电网运行所带来的问题进行了分析,并提出了可能需要采取的相应措施。

Datang 110kV cable line has very short construction period but difficulties such as adverse geological impact, delay due to serious leakage heavy construction task. Facing of foundation pit and experiences of rainy season and hot summer weather of southern area during construction, the fabrication and installation of 110kV cable terminal head and middle joint and the installation of cable conduit etc. key processes are qualified in electrical tests only once based on scientific planning and adopting of powerful measures. The initial charging commissioning of power transmission project is successful. Based on introduction to the whole process of construction management of Datang 110kV cable line and in combination of actual situations of the project, the paper makes a deeply study and discussion on how to improve project quality, accelerate progress and save investment.
