针对核电站内部运行复杂,对电网变化敏感,数学模型阶数太多的特点,基于PSCAD(Power Systems Computer Aided Design)电磁暂态仿真平台,建立了能反映核电站内部动力部分功率调节特性和并入电力系统运行过程动态情况的一体化仿真平台。利用PSCAD较强的动态控制能力和丰富的库元件模块,通过仿真分析证明了动力部分所具有的功率调节能力并在核电站外接无穷大系统后分析了负荷跟踪过程中核电站的受干扰能力,验证了模型的正确性和适用性。
In view of the complex operation inside the nuclear power plant, sensitive to grid changes and too many mathematical models, based on the electromagnetic transient simulation platform of PSCAD (Power Systems Computer Aided Design), a system can be established that can reflect the power regulation characteristics and power incorporation System operation process dynamic simulation platform. By using the strong dynamic control ability of PSCAD and rich library element module, the power regulation capability of the power part is proved through the simulation analysis and the interference ability of the nuclear power station during the load following process is analyzed after the nuclear power plant is connected with the infinite system. The correctness and applicability.
