本文采用特征线法加调速器方程、机组惯性方程计算了南丫河二级水电站2号机的甩负荷过程,除小开度情况外,计算和试验实测结果相当吻合。
In this paper, the load-shedding process of No.2 unit of Nanye River Hydropower Station II is calculated by the characteristic line method plus governor equation and the unit inertia equation. Except for the small opening, the calculation and experimental results are in good agreement.
