摘要
为了平滑反推的小时入库流量的异常锯齿状波动,基于水库水量平衡原理,提出了物理机制驱动的集合卡尔曼滤波(EnKF)方法。以乌江渡水库为例,验证了该方法对典型入库流量过程中异常波动的修正效果。研究结果表明:EnKF方法处理后的入库流量序列在平滑度和上下库水量约束指数方面均优于三点滑动平均法和五点三次滑动平均法。
To smooth out the abnormal zigzag fluctuations in reservoir hourly inflow data,a physical mechanism driven ensemble Kalman filter(EnKF)method is proposed based on the reservoir water balance principle.Taking the Wujiangdu Reservoir as an example,the correction effect of the proposed method on abnormal fluctuations in typical inflow processes is verified.The results show that the EnKF method outperforms the three-point moving average method and the five-point three-order moving average method in terms of the smoothness and the upper and lower reservoir water storage constraint index of the corrected inflow sequence data.
