考虑机组爬坡率的火电系统日发电计划编制

Daily Ceneration Schedule for Thermal Power System under Consideration of Unit Ramp Rate

机组爬坡率(即机组的升、降负荷能力)是火电机组正常运行的一个重要参数,因此,在编制火电系统日发电计划时必须充分考虑火电机组的爬坡率约束。介绍一种以购电费用最小为目标、火电机组按照电价竞争上网的新算法,算法的主要优点是既能满足机组的爬坡率约束又能很好地满足各时段的负荷需求。

Unit ramp rate is a very important parameter for unit running,so it must be seriously concerned when dis-patching unit schedule for thermal power system.This paper presents a new method which considering unit ramp rate and system load balance aims at minimizing the system purchase cost.
