| 摘 要： | 水轮机非固定模式导叶关闭规律是指按水轮机初始工况参数适时地确定最佳导叶关闭方式。这种适时的水轮机导叶关闭方式对于水电站大波动过渡过程具有较好的参数控制作用,能在不改变任何基础设施的前提下降低水电站过水系统最高水锤压力和机组转速,给水电站的运行带来较大的经济效益。在对非固定模式导叶关闭规律的优化中遗传算法有较高的优化效率,其中主要表现在算法简单、全局搜索性好、收敛性高、优化结果稳定。

| Abstract: | The unfixed wicket gate closing law means that the governor, according to the turbine original parameters, selects the best closing laws timely, which have better parameters control especially for the big fluctuate transient process of the power plant. This closing law can reduce the maximum value of water hammer pressure and runaway speed without changing any basic facilities, which can bring a great benefit to the power plant. The genetic algorithm has a better optimizing efficiency during the unfixed wic... |
