本文分别按刚性水锤和弹性水锤两种理论建立了单机——远距离输电——无穷大电力系统状态方程。并按此两种数学模型,针对不同引水管长进行最优控制系统的参数设计的研究。 对最优控制系统的模拟结果表明:寻叶最优控制系统不仅在小干扰情况下,而且在大干扰情况下能明显地改善水轮发电机组的动态品质。 本文还研究了引水系统数学模型对最优控制系统的设计及其对控制效果的影响。
In this paper, two kinds of theories of rigid water hammer and elastic water hammer are respectively used to establish the state equation of single-long distance transmission-infinite power system. According to these two mathematical models, the parameter design of the optimal control system for different length of diversion pipelines is studied. The simulation results of the optimal control system show that the optimum control system of the leaf picker can not only improve the dynamic quality of the hydroelectric generating set not only under the condition of small disturbance but also under the condition of large disturbance. The paper also studies the design of the optimal control system and its effect on the control effect of the mathematical model of water diversion system.
