| 摘 要： | 水轮机在实际运行中存在振动区,水电机组需避免在此区间运行。为此建立了考虑水轮机振动区的水电机组组合优化的发电量最大数学模型,利用分支定界法确定了机组的运行区间,并采用动态规划方法求最优解。实例应用结果表明,分支定界与动态规划相结合的方法适合于水电机组的实际运行情况,且提高了求解精度。

| Abstract: | Hydro turbines may be running in the vibration zone, so hydropower units are forbidden to run in this zone. The mathematical model of hydropower unit commitment with maximum electricity is established by considering vibration zone. The branch and bound method is used to determine operating range of generating set and the optimal solution are obtained by using dynamic programming. The example results show that the proposed method is fitted for solving hydropower unit commitment and improves the solution precision. |
