雅砻江大型水电站泄流曲线率定方法研究

摘要

According to the characteristics of reservoir and the operation characteristics of unit with loading,as well as the operation requirements of flood discharge gate,the water level-flow relationship curve and flow coefficient method are chosen to calibrate the discharge curve of flood discharge gate.The calibration results are analyzed,and show that the discharge data based on the empirical value of comprehensive flow coefficient are more reasonable,and the calibration results based on levelflow relationship curve are more practical and easy to be used in routine reservoir scheduling.%根据电站水库的特性和电站机组带负荷的运行特点,以及泄洪闸门的运行要求,确定了选用水位流量关系和流量系数法进行泄洪闸门泄流曲线率定,并对率定结果进行了分析,得出基于综合流量系数经验取值求得的泄流数据更为合理,而关系曲线法率定的结果实用性较高便于在日常水库调度中推广.
