以AP1000为代表的第3代核电技术是我国核电当前的发展方向。该文提出用于电网稳定仿真的先进压水堆核电AP1000建模方法,建立相应的简化实用模型,并在电力系统全过程仿真软件中编程实现。鉴于AP1000核电机组目前尚未投运,采用参考核电站AP1000机组的全范围仿真机对模型进行验证。结果表明,该模型较为准确地反映了先进压水堆AP1000的动态特性,为研究核电机组运行机理及其与电网之间的协调控制提供了重要的仿真工具。
The 3rd generation nuclear power technology represented by AP1000 is the current development direction of nuclear power in our country. This paper presents an advanced PWR nuclear power AP1000 modeling method for power system stability simulation. The corresponding simplified and practical model is established and programmed in the whole process simulation software of power system. In view of AP1000 nuclear power unit is not yet put into operation, the model is verified by reference to the full range of nuclear power plant AP1000 unit simulation. The results show that the model accurately reflects the dynamic characteristics of the advanced PWR AP1000 and provides an important simulation tool for studying the operating mechanism of nuclear power units and their coordination with the power grid.
