摘要
根据压水堆核电厂物理过程的热工水力学分析和能量转化与传递规律,在电力系统分析综合程序(PSASP)中建立了适用于核电厂内部动态和电力系统暂态稳定计算的压水堆核电厂的集总参数模型。仿真分析了核电机组的功率调节特性,包括自稳定性、自调节性和功率调节系统作用下的功率阶跃和线性升降特性等。结果表明,由于负温度效应,压水堆具有自稳定性和自调节性,可承受一定的外部干扰和至少10%Pn的功率阶跃;在功率调节系统作用下,核电机组的功率调节速率可达到5%Pn/min,能满足电网调峰的要求。
Based on the energy transformation regularity in physical process of pressurized water reactors（PWR）,PWR NPP models are established in PSASP（Power System Analysis Software Package）,which are applicable for calculating the dynamic process of PWR NPP and power system transient stabilization.The power dynamic characteristics of PWR NPP is simulated and analyzed,including the PWR self-stability,self-regulation and power step responses under power regulation system.The results indicate that the PWR NPP can afford certain exterior disturbances and 10%Pn step under temperature negative feedbacks.The regulate speed of PWR power can reach 5%Pn/min under the power regulation system,which meets the requirement of peak regulation in Power Grid.
