摘　　要：通过监测数据分析,叠梁门运行对下泄水温影响会受边界条件年际变化和仪器误差等同量级因素干扰,难以准确得出叠梁门的实际运行效果。针对该问题,研究提出了通过分析叠梁门调度前后机组水温变化的方法来分析叠梁门运行效果,以溪洛渡水电站为研究对象进行方法论证。结果表明,该方法的有效性在溪洛渡水电站上得到了合理验证,可为叠梁门实施效果评估引入新角度和新方法。Based on the analysis of monitoring data, the influence of stoplog gate operation on the discharge water temperature will be disturbed by the inter-annual variation of boundary conditions and instrument error, so it is difficult to accurately obtain the actual operation effect of stoplog gates. To solve this problem, a method of analyzing the change of unit water temperature before and after stoplog gate dispatching is proposed to study the operation effect of stoplog gates, and Xiluodu Hydropower Station is taken as the research object for method demonstration. The results show that the effectiveness of this method has been reasonably verified in Xiluodu Hydropower Station, which introduces a new method to evaluate the effect of stoplog gate operation.
