本文应用非线性规划,优选规划阶段的水电站群的主要设计参数,并提出了相应的数学模型和算法。这一模型能较好地适应水电系统大规模和非线性的特点,在考虑水电站群跨流域补偿调节的条件下,同时优选各个水库的正常蓄水位和死水位,同时优选各水电站的最佳装机规模及其装机程序,使规划期内全电力系统的总费用现值最小。 本文曾结合某电力系统,对分布在四个不同流域上的五座具有不同调节性能的水库,和十一个水电站所组成的系统,对待建水电站进行了参数优选,得到了比较满意的结果,已提供有关部门在规划阶段中参考。
In this paper, the main design parameters of the hydropower station group in the planning stage are optimized by using nonlinear programming and the corresponding mathematical models and algorithms are proposed. This model can be well adapted to the large-scale and nonlinear characteristics of hydropower system. Under the conditions of compensation and adjustment of inter-basin flow of hydropower stations, the normal water level and dead-water level of each reservoir should be optimized simultaneously, and the optimum of each hydropower station should be optimized Installed capacity and its installed process, the total cost of the entire power system during the planning period the present value of the minimum. In this paper, we combine a power system with five reservoirs with different regulating performance in four different basins and eleven hydropower stations, and optimize the parameters of the hydropower station to be built. Satisfactory results are obtained, Relevant departments have been provided with reference to the planning stage.
