以双牌水电站为例,针对水库入库过程推算结果的“锯齿”现象,构造了入库流量与时间的多项式关系进行平滑模拟,并建立以水量平衡为约束的最小二乘曲线拟合模型求解。结果表明,该方法确保了模拟结果与原始过程计算周期内水量相等、误差权重系数具有相同最大值的特征,拟合效果、精度较高。 Taking Shuangpai Hydropower Station as an example, this paper constructs a polynomial relationship between the inflow flow rate and time for smoothing simulation and establishes a least square curve fitting with water balance as the constraint Solve the model. The results show that this method ensures that the simulation results are equal to the amount of water in the calculation cycle of the original process and the error weight coefficients have the same maximum value, and the fitting effect and accuracy are high.
