Embodiment Construction
[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] The invention relates to a paddle association method for variable speed operation of a paddle type water turbine. Firstly, according to the comprehensive characteristic curve of the paddle type water turbine, the unit output curves of each operating point are drawn, and then according to the equal unit output curves, the paddle type water turbine is drawn with variable speed. Run the optimal characteristic curve, and finally read the guide vane opening α and blade opening at each working point on the optimal characteristic curve of the rotary paddle turbine running at variable speed That is, the paddle association relationship of the rotary paddle turbine running at variable speed.
[0020] Specifically follow the steps below:
[0021] Step 1, according to the unit flow Q 11 is the abscissa, unit speed n 11 is the unit flow rate Q ...
