奉新县是全国一百个农村电气化试点县之一,小水电装机虽已超过1万千瓦,但调节性能较好的只有老愚公电站(多年调节)。如何合理调度水量极为重要,我们采取了“先径流后库水”的原则,在汛期让径流式电站满发,使具有多年调节的老愚公电站尽量少发电多蓄水,从而在满足系统负荷要求的前提下,提高了枯水期的出力。根据这种调度方式,经分析计算在保证率为80%的情况下即可提高保证出力1105千瓦,大大地提高了供电的保证程度,发挥了水库的调蓄作用。
Fengxin County is one of the country’s 100 pilot counties for rural electrification. Although the installed capacity of small hydropower has exceeded 10,000 kilowatts, only the foolish public power station (which has been adjusted for many years) has better regulatory performance. How to properly regulate the amount of water is very important. We adopted the principle of “runoff first reservoir water”, make run-of-river power plants full during the flood season, and make old-staged public power stations with multi-year regulation minimize power generation and multiple water storage, Requirements under the premise, improve the dry season’s output. According to this scheduling method, the guaranteed output of 1105 kilowatts can be increased with the guarantee rate of 80%, which greatly improves the degree of assurance of power supply and plays a role of reservoir regulation and storage.
