摘要
在MATLAB软件中对320 MW供热机组与飞轮储能进行了建模,搭建了包含飞轮储能的供热机组两区域电网调频模型。在阶跃负荷扰动下,对比分析了耦合飞轮储能后的供热机组主要参数波动情况,结果显示在飞轮储能辅助机组调频后,供热机组汽轮机功率、供热抽汽压力及电网频率的波动情况均有了明显改善,有利于提高机组运行的灵活性与稳定性。
The 320 MW heating unit and the flywheel energy storage are modeled in MATLAB software,and the two-region power grid frequency regulation model of the heating unit including the flywheel energy storage is established.Under the step load disturbance,the fluctuations of the main parameters of the heating unit after the coupled flywheel energy storage are compared and analyzed.The results show that after the frequency regulation of the flywheel energy storage auxiliary unit,the fluctuations of the turbine power of the heating unit,the pressure of heating and extraction steam and the frequency of the grid have been significantly improved,which is beneficial to improve the flexibility of the unit operation.
