摘要
运用外特性数值解法，结合汤峪水电站具体情况，建立了突甩负荷过渡过程求解的数学模型，并编制了计算程序；针对不同导叶关闭规律和不同调压阀行程及其组合情况，进行了多种方案的求解，从而了解了有关水力要素及机组工况参数的瞬变规律。
Using external characteristic numerical solution method in combination with condition of Tangyu Hydroelectric Plant,the paper establishes the mathematical model for solution of abruptly unloading transient process.In accordance with the closure law of different guide vanes,the travel of different regulating valves and their combination,the solution of varied alternatives is carried out,so the instantaneus variation law of concerned hydraulic elements and unit operation parameters is found out and the basis for safe and stable operation of plant is presented.
