三峡水库入库径流预报对年发电量的影响

Influence of inflow forecast on annual energy output of Three Gorges Reservoir

根据入库径流预报资料对三峡水库进行中期优化调度。研究入库径流预报的质量对年发电量的影响。从总体上看,预报精度越高,年发电量越大。在3~7 d的时域内,预见期越长,年发电量越大。

According to the inflow forecast data,the mid-term regulation of Three Gorges Reservoir is carried out to study the influence of forecast accuracy on the annual energy output of Three Gorges Hydropower Station.In view of the integral benefits,the higher the forecast accuracy,the more the annual output.In 3~7 days time domain,the longer the forecast time in advance,the more the annual output.
