导叶关闭规律的优化及对水力过渡过程的影响

Optimization of Wicket Closure Rule and Influence on\=Hydraulic Transients for Water Power Station

优化导叶关闭规律是解决水电站机组调节保证计算的一个重要的手段。然而面对实际工程问题时如何优化导叶关闭规律、不同的导叶关闭规律对水力过渡过程有何不同的影响、选取的导叶关闭规律能否安全有效地实现等，至今缺少明确的答案和恰如其分的评价，以致难以发挥导叶关闭规律应起的作用。本文从结合国内某些大型水电工程。

The optimization of wicket closure rule is a main method that has been extensively applied to the calculation of hydraulic transients for water power station. However, facing to complex hydroelectric projects, there is not a clear answer, and apt appropriate criterion, such as how to optimize wicket closure rule, how to carry out safely and effectively wicket closure rule, and how to influence on hydraulic transients. The paper discussed these questions and given relevant suggestions that are based on the results of theoretical analyses, model tests, and numerical calculations.\;
