摘要
为提高抽水蓄能电站正常运行期设计发电库容的保证程度,在运行期补水不足时需要设置能够补偿水量损失的水损备用库容或采取补水措施。笔者主要研究水损备用库容的计算方法,通过梳理水损备用库容计算的边界条件,着重分析偏不利工况下的水库蒸发、渗漏损失,结合水量平衡方程,建立水损备用库容计算数学模型。经实际工程验证分析结果表明,计算成果在合理范围内,文中提出的数学模型可为抽水蓄能电站水损备用库容设置的必要性和设置规模提供重要参考。
In order to improve the guarantee degree of the designed power generation storage capacity of the pumped storage power station during the normal operation period, it is necessary to set up the water loss reserve storage capacity that can compensate the water loss or take the water supplement measures when the water supplement is insufficient during the operation period. This paper mainly studies the calculation method of water loss reserve storage capacity. By combing the boundary conditions of water loss reserve storage capacity calculation, it focuses on the analysis of reservoir evaporation and leakage loss under unfavorable conditions.Combined with the water balance equation, the mathematical model of water loss reserve storage capacity calculation is established. The results of practical engineering verification and analysis show that the calculation results are within a reasonable range. The mathematical model proposed in this paper can provide an important reference for the necessity and scale of water loss reserve storage capacity setting of pumped storage power station.
