具有核电模型的中期动态模拟程序开发及大型核电站与电力系统相互影响的研究

DEVELOPMENT OF MIDTERM DYNAMIC SIMULATION PROGRAM INCLUDING NUCLEAR PLANT MODEL AND STUDY OFINTERACTION BETWEEN LARGE EUCLEAR POWER PLANT AND POWER SYSTEM

本文在新研制的详细的核电模型基础上，开发了包括该模型在内的相应的电力系统中期动态稳定程序。由此，应用数字模拟技术分析了大扰动下的核电机组的动态行为，并以两广香港互联系统为例，分析了大型核电站（大亚湾核电站）接入系统后机网间的相互影响，提出了改进系统稳定性能的措施。

Based on the newly deve loped detailedmodel of Pressurized Water Reactor(PWR)NuclearPower Plant(NPP),the corresponding midterm dy-namic stability program including this model is devel-oped.The dynamic behavior of PWR generation unit isanalyzed under large disturbances in power system us-ing digital simulation technique.The interconnectedpower system of Guangdong, Guangxi and Hongkong(GGH)is taken as a studv system.The interaction be-tween the NPP and the power grid is studied after in-tegrating large sized NPP(Daya Bay NPP)into GGHinterconnected power system and the measures for im-proving the stability performance are presented.
