摘　　要：随着我国核电的快速发展,核电装机不断增加。但是目前我国核电机组由于各种原因,始终是以基本负荷模式运行,不参与电网调频,这对电网频率的控制带来了巨大冲击。针对此问题,以大亚湾核电站为研究对象,对核电机组参与电网一次调频的可行性进行了研究。建立了压水堆核电机组全电厂的非线性时变动态模型,用FORTRAN语言编写了动态计算程序。然后把动态计算程序编译为动态链接库文件,并通过以S函数的方式接入Matlab/Simulink仿真平台,在Matlab/Simulink中进行了核电机组一次调频仿真平台搭建和一次调频动态仿真。仿真结果表明,在目前核电机组的设计下,核电机组从安全性和经济性上可以参与电网一次调频。Along with rapid development of nuclear power in China, installed capacity of nuclear power units is increased unceasingly. Due to various reasons at present the nuclear power units in China are operated in basic-load running mode and do not participate in power grid frequency regulation, and it greatly affects the control of grid frequency. In allusion to this phenomenon, taking the Daya Bay nuclear power plant as research object, the feasibility of nuclear power units participating primary frequency regulation （PFR） of power grid is researched. A nonlinear time-varying dynamic model of overall nuclear power plant composed of pressurized water reactor （PWR） nuclear power units is established, and using FORTRAN language a dynamic calculation software is programmed. Then the dynamic calculation program is compiled as dynamic link library （DLL） files and embedded into Matlab/Simulink simulation platform in the form of S-function, and then in Matlab/Simulink environment a PFR simulation platform of PWR nuclear power units is built, and dynamic simulation of PFR is performed. Simulation results show that under current design of PWR nuclear power units it is feasible for PWR nuclear power units to participate PFR in the viewpoint of economy and security.
