三峡水库动库容特征及其在防洪调度上的应用:2.动态汛限水位调度方法
Dynamic storage of Three Gorge reservoir and its application to flood regulations: 2.Flood regulations with dynamic flood control levels
摘要
Abstract
Based on the sensitivity of water stage variation, a dynamic flood control level (DFCL) method is proposed for the flood regulations of the Three Gorge reservoir ( TGR) . During the summer season, if no floods, the pool level can be elevated to 150m to increase power generation, and as long as a high flood is forecasted, the pool level can be lowered to the designed 145m or even as low as to 135m in time by increasing the relase of the TGR, utilizing l-2days forecast of in-pool floods. An operating model for the TGR has been developed to analyze the different operation schemes. The simulations show that operation by the DFCL can satisfy the flood control requirements for different designed flood of P = 1 % and 0.1% by increasing the flood control capacities and result better consequence of flood control than the original operation with fixed FCL at 145m. Both benefits in flood control and electricity generation can be boost up with the DFCL. This scheme can also increase the variation of pool levels that may be able to improve the ecological conditions.关键词
