摘要
基于反馈算法根据实测库水位与目标库水位之间的差值计算闸门应该释放的流量,以达到维持库水位在目标值的目的。该文将该方法应用于一座湖泊型水库的调洪过程中,并采用数值方法计算库水位变化过程,计算结果表明,采用反馈控制可有效地将库水位维持在目标值附近,并且与采用人工控制相比,反馈控制下的库水位相对于目标值的累计误差减小了78%。
Using the feedback control algorithm,the current and historical reservoir stages are exploited to determine the target discharge at next operation time,which is converted to the target opening using the gate discharge formula.The method is applied to the flood regulation of a lake-type reservoir,the calculation shows that this method can maintain the reservoir stage at the target level efficiently and limit the discharge at the same time,in comparison with manual operation,the total variation of reservoir stage with respect to the target level is reduced by 78%.
