| 摘 要： | 核电机组具有不同于常规机组的特性,接入电网后会与电网产生较为严重的相互影响。在电力系统分析综合程序中,建立了压水堆核电机组自定义模型,研究了电网电压、频率扰动对核电机组的影响,分析了电网故障引起的核电厂动态响应及核电机组切机对电网的影响,并提出了安全稳定控制措施与策略。仿真结果表明,核电机组会受到电网频率和电压扰动的影响,它对电网频率和电压有较高要求。如果电网故障能迅速清除,且电网保持稳定,核电机组则可承受电网中的较大扰动。

| Abstract: | Nuclear power plants(NPP) have different characteristics from the conventional unit.Integrating NPPs into power systems will result in serious mutual influence.The user-defined model of pressurized water reactor(PWR) NPP was established based on power system analysis software package(PSASP),and then the influence of the grid voltage and frequency disturbance to the NPP was analyzed.By PSASP,the dynamic response of NPP to power grid faults and the influence of tripping NPP on the power grid were calculated.The control measures of security and stability were proposed.The simulation results show that,NPP will be affected by grid frequency and voltage disturbances and it requires higher quality of grid voltage and frequency.If the system fault can be cleared quickly and the power grid remains stable,NPP can withstand large disturbances from the power grid in some extent. |
