摘要
为研究核电厂接入电力系统后二者之间的相互影响,利用电力系统分析综合程序(power system analysis software package,PSASP)的用户自定义建模功能建立压水堆(pressurized water reactor,PWR)核电厂主要环节的数学模型。该模型将压水堆核电厂动力部分作为发电机调速器,可与电力系统连接,计算核电厂与电力系统之间的动态过程。在PSASP中使用该模型计算核电机组的自稳定性、自调节性和接入单机无穷大系统的故障响应,验证了模型的正确性和适用性。此外,由于压水堆的负温度效应,核电机组可承受一定的外部干扰和功率阶跃。若电网故障切除迅速,核电厂与电力系统之间的相互影响很小。
To analyze the interactions between power system and system interconnected nuclear power plant （NPP）, the mathematical model of pressurized water reactor （PWR） NPP were established by the user-defined modelling function of power system analysis software package （PSASP）. The motivity part of PWR NPP was treated as turbine speed governor of PSASP＂ generator model. The model can be integrated into power system simulation and was applicable to calculating the dynamic process of interaction between PWR NPP and power system. Calculation results of PWR NPP self-stability, self-regulation characteristics and responses to fault in single machine infinite bus system proved the model validity in PSASP. In addition, due to temperature and poisoning negative feedbacks, PWR NPP can withstand certain disturbances including step power. If power system fault were removed quickly enough, the interaction effects between power system and NPP are insignificant.
