大型水电站枯水期典型月运行方式的分析与优化

Analysis and Optimization of the Typical Monthly Operation Mode in Low Water Season for Large Hydropower Stations

结合二滩水电站近年来枯水期典型月份的实际运行状况和运行数据与前一年的数据进行类比分析,通过简单的算术计算,说明水电站在机组运行方式和厂用电运行方式上可以进行优化;重点对枯水期机组实际运行方式进行了经济性和可行性分析,通过电网负荷变化的特点和电网接线方式以及备用容量规定的要求,优化了机组的运行方式。

The practical monthly operation conditions and operation data of the Ertan Hydropower Station in low water season are compared and analyzed. It shows that the operation modes of the generator units and the station service power could be further optimized. The economics and feasibility of the unit practical operation mode in the low water season are analyzed. Considering the load changes and connection mode of the power grid,and the requirement of the standby capacity,the unit operation mode is optimized.
