【摘要】 为解决5个串并联水电站的联合调度问题,采用相对比较的方法,在同一计算条件下,将系统分解为三峡梯级与清江梯级2个子系统,分别建立子系统数学模型;通过优化方法求解,得到未联合调度时的发电量;然后建立系统联合调度数学模型,分解协调模型将2个子系统联合优化,得到系统联合调度时的发电。经过对比分析,三峡梯级与清江梯级联合调度后年均可获得补偿电量18.29亿kW.h。更多还原

【Abstract】 This article studied the united operation of five hydropower stations and adopted the comparative method.On the same condition,the system was firstly divided into two subsystems,i.e.the Three-gorges cascade and the Qingjiang cascade,modeled and solved respectively by optimal algorithm,and individual operation results were gained.Then,united operation mathematics model of two subsystems was established and solved by decomposing-concordance algorithm,and united operation results were obtained.At last,calculated results through contrastion indicated that united operation could get more than(1.829) billion kilowatt-hours’ electric power.更多还原
