澜沧江中下游梯级电站发电与生态需水耦合优化研究

摘要

随着澜沧江中下游河段梯级电站的开发完成,发电、防洪、生态、航运等综合利用需求之间的矛盾日益突出.通过耦合优化算法和多元线性回归模型,在现有实际运行资料的基础上,研究多目标约束条件下梯级电站的运行方式,在满足生态调度目标的前提下,实现发电效益的最大化,并对今后澜沧江流域梯级电站生态优化调度提出建议.%With the development of cascade hydropower stations in the middle and lower reaches of Lancang River,the contradictions between power generations,flood control,ecology and shipping is becoming more and more prominent.Based on existing practical operation data,the operation modes of cascade hydropower stations under the condition of multi-objective constraint are studied by using coupling optimization algorithm and multiple linear regression models.The operation modes will achieve maximum power generation benefit under the premise of satisfying ecological scheduling goals.The suggestions on ecological optimal scheduling of cascade hydropower stations in Lancang River Basin in the future are also presented.
