摘　　要：以某电厂350MW热电联产机组为例,介绍了低压缸零出力改造方式,结合试验数据对比分析了低压缸零出力改造前后供热能力和调峰能力,并从热耗率和调峰收益量方面对机组运行经济性进行分析计算。In recent years,zero output of low-pressure cylinder transformation has been widely used because of its less investment,minor modification and flexible adjustment.Taking a 350MW cogeneration unit for example,the paper presents transformation ways of low-pressure cylinder zero output.According to test data,heating capacity and peak regulation capacity before and after low-pressure cylinder zero output transformation is comparatively analyzed.And operating economy of cogeneration unit is also analyzed and calculated from the perspevtive of both heat rate and peak regulation revenue in the paper.

关 键 词：低压缸零出力 供热能力 调峰能力 经济性
