对乌江梯级龙头水库调度方式的探讨

乌江具有多年调节性能龙头水库的洪家渡水电站建成投运后,在2005~2006年其水库运行过程中出现了“下游水库严重缺水,龙头水库停机蓄水”的不利运行方式,因此如何发挥龙头水库的调节作用成了贵州乌江水电开发有限责任公司和贵州电网调度部门面临的一项重要课题。本文通过2005年、2006年2年的水库运行过程分析,阐述了洪家渡水库不同时段对下游水电站的补偿调节作用,提出了龙头水库拦蓄和补偿调节的辨证的观点,即充分发挥补偿调节作用提高下游各水库运行水位,从而保证梯级水库经济运行,提高水能利用率。

Inquiring into The First Reservoir Dispatching Model of Wujiang Cascade Hydropower Stations

After Hong, jiadu Hydropower Station, the first reservoir of the Wujiang River cascade stations with long- period storage, was put into operation, the operation model of serious lock water in downstream reservoirs and storing water but stopping generation in the first reservoir appeared in operation process during 2005 -2006. An important job faced is how to bring the first reservoir into play its regulating role. Analyzing on reservoir operation process during two years of 2005 and 2006, the writer expounded the regulating and compensating role of Hongjiadu Reservoir to downstream stations in different periods, presented a dialectical review point between storage and regulation.
