Abstract:
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.
