由H-P曲线计算振动区的单库水电站机组组合问题研究

Study on Combination of Single Reservoir Hydropower Station Units Based on H-P Curve Calculation for Vibration Area

针对传统水电机组组合运行中容易出现振动故障的问题提出解决措施:先通过各台机组的实际水头H和一定导叶开度下有功出力P之间的变化规律,绘制出水头H和其对应的振动区边界的关系曲线,通过振动区边界曲线便可以求出每台机组自身的振动区域,然后运用动态规划法((dynamic programming method,DP)进行实际编程计算。最后通过某水电站的运行实例验证了所提方法的可行性。

Aiming at vibration fault in traditional hydropower units combination, this paper proposes suggestions which is firstly to draw relationship curve of waterhead H and its vibration area boundary according to change rule of practical water- headH of each unit and active power output P under a certain guide vane opening by which it is able to determine vibration area of each unit own. Then by using dynamic programming method to proceed practical programme calculation and at last to verify feasibility of this method by practical operation of one hydropower station.
