System and method for automatically balancing pressure and opening hydropower station tail water gate
The invention provides a system and method for automatically balancing pressure and opening a hydropower station tail water gate and belongs to the technical field of hydropower station automatic control.. The system comprises a water pipe, the water pipe is pre-buried in a tail water gate pier of a hydropower station so as to guide water from a downstream tail water riverway to a machine pier wall in a hydropower station workshop and is connected with a water turbine tail water pipe, and an overhaul valve and an electric butterfly valve are further arranged on the water pipe. The problems that according to an existing method, holes are formed in a gate, water leakage points of the gate can be increased, sealing and the structure of the holes need to be well processed, water energy resources are wasted due to the fact that pressure is balanced in a mode that water is led from an upstream volute, and meanwhile pressure reduction is needed if a water source of a power station is high aresolved.
本发明提供一种自动平压开启水电站尾水闸门的系统及方法，包括水管，水管预埋于水电站的尾水闸门闸墩内，以将下游尾水河道的水引至水电站厂房内的机墩壁并与水轮机尾水管相连，水管上还设置检修阀和电动蝶阀。以解决现有方法采用闸门上开孔会增加闸门的漏水点，需要处理好开孔处的密封与结构，而采用从上游蜗壳引水平压，则浪费了水能资源，同时如果电站水头较高还需要减压等问题。属于水电站自动控制技术领域。
