为研究故障扰动下电力系统和核电机组的动态行为及机网间相互影响,有必要建立适合于电力系统中长期稳定分析的核电站详细数学模型。介绍了田湾压水堆核电机组数学模型的建立,并利用PSS/E的用户自定义模型实现,仿真分析了田湾核电机组对江苏电网系统扰动的响应。
In order to study the dynamic behavior of power system and nuclear power unit and the interaction between networks under fault disturbance, it is necessary to establish a detailed mathematical model of nuclear power plant suitable for long-term stability analysis of power system. This paper introduced the establishment of the mathematic model of Tianwan PWR nuclear power plant, and realized the simulation with PSS / E user-defined model. The response of Tianwan nuclear power plant to the disturbance of Jiangsu power system was analyzed.
