Analysis and Application in Peak Regulation Characteristics of Single Regulated Extraction Turbine

由于供热式汽轮机组参与电网调峰的能力受到该汽轮机供热负荷的影响,为了得到供热式汽轮机的电负荷和热负荷的关系,以一次调节抽汽式汽轮机为例,依据工况图对其热、电负荷特性进行分析研究后,通过热力性能试验进行验证和修正,得出了一次调节抽汽式汽轮机在满足外界热负荷情况下的电负荷特性,为合理安排供热式汽轮机组参与电网调峰提供了依据。

Due to the influence of turbine load ＂for thermal supplication on the electric network peak regulation ability of heat supplication units, in order to obtain the relationship between the electric load and thermal load of heat supplication, taking the single regulated extraction turbine as an example, after analysis and research on thermal and electric load char acteristics with working conditions chart, this paper obtains electric load characteristic of single regulated extraction turbine in the condition of meeting external thermal load, supplies the basis of regulating extraction turbine participating in the electric network peak regulation.
