潘家口水电站二期工程引进三台意大利TIBB-DPEW公司制造的混流可逆式水泵——水轮机组。其单机容量达90MW。目前正在安装调试,不久即将正式发电。为了获得该转轮静特性曲线,确定水轮机、水泵工况的稳定运行条件,核对意方提供的调节保证电算成果,并选择导叶最佳关闭规律。我们利用该公司提供的模型转轮,进行从压力管道进口(包括拦污栅)到尾水管出口全模拟稳态、动态以及机组稳定性等试验研究,为设计部门和电站安全运行提供试验依据。本文仅就动态试验成果进行初步分析,供有关部门参考。
Panjiakou Hydropower Station Phase II project to introduce three Italian TIBB-DPEW company to create a reversible flow reversible pump - turbine. Its stand-alone capacity of 90MW. It is currently being installed and commissioned, and will soon be officially commissioned. In order to obtain the static characteristic curve of the wheel, determine the stable operating conditions of the turbine and the pump, check the regulation guarantee result provided by Italy, and select the optimal closing rule of the guide vane. We use the model runner provided by the company to carry out experimental research on the full simulation of steady-state, dynamic and unit stability from the inlet of the pressure pipe (including the trash rack) to the draft pipe outlet, which provides experimental basis for the safe operation of the design department and the power station. This article only preliminary analysis of the dynamic test results for the relevant departments for reference.
