摘要
本文结合毛家河水电站实际情况,根据水轮机调压阀流量与时间关系的假设,计算各工况下调节特性、流量与时间变化,机组最大压力上升率和最大转速上升率等参数,并对调压井工程量及投资进行了估算,经过水轮机调压阀和调压井两种方案比选,确定采用水轮机调压阀方案经济、合理。
By combining with the actual situation in Maojiahe Hydropower Station and following the hypothesis on flow and time of pressure regulating valve in the water turbine, this article calculates changes of adjustment traits, flow and time, maximum pressure rise rate and maximum rotation speed rise rate. It estimates work amount and investment of surge tank. After contrasting two schemes namely pressure - adjusting valve of water turbine and surge tank, it determines that use of pressure - adjusting valve of water turbine is economical and reasonable.
