摘　　要：随着我国电力辅助服务市场政策的出台,供热机组的灵活性改造获得了快速的发展。针对不同供热改造技术的性能优劣问题,以国产300MW机组为例,对其应用不同供热改造技术的灵活性和经济性进行了全面的论述及分析。结果表明:旁路供热的灵活性最好,不考虑调峰电价补贴时低真空供热的经济性最好,考虑电价补贴后背压供热的经济性最好。研究成果可为同类型机组的灵活性改造技术路线的选择提供参考。With the introduction of the market policy of power auxiliary services, the transformation technology of heating units with better flexiblity has been developed rapidly. Taking 300 MW unit as an example, the flexibility and economy of different heating transformation technologies are discussed and analyzed comprehensively. The results show that bypass heating has the best flexibility;low-vacuum heating has the best economy without consideration of peak load regulation price subsidy;however, if considering the subsidy, back pressure heating has the best economy. The research results can provide reference for the selection of flexibility transformation technology for the same type of units.
