摘　　要： 从世界能源转型的历史进程和视野论述了燃煤热电联产发展为天然气冷热电联供的必然性;剖析了能源生产和供应的集中与分散的关系.论述了相对于集中的千MW级煤、水、核电主力基荷机组,百MW级天然气发电属于分布式能源.中国"十二五"将建设的一大批支撑地方新区域经济发展的百MW级天然气冷热电联供分布式发电项目(DES/CCHP),绝大多数能够以16 h/d模式运行,肩负起提高能效、保障新区能源、开拓天然气下游市场、提高电力供应可靠性和调峰的四重使命;均可按"天然气冷热电联供调峰电站"审批,门槛是能效高于70%.10 MW及以下的小型DES/CCHP按自备电站审批. From the historic process and vision of the world's energy transformation,the necessity of coal-fired cogeneration developing into natural gas CCHP is expounded.The relation between centralization and decentralization in energy production and supply is analyzed.Comparing with centralized coal,water,nuclear gigawatt-class units supplying main base load,100 MW-class gas generation belongs to distributed energy.In the 'Twelfth Five Plan',a large number of 100 MW-class DES/CCHP projects supporting the local economic development of new district will be built.Most of them can operate on 16h/d mode and they also take the mission of improving energy efficiency,ensuring the new district's energy,opening up downstream gas market and increasing power supply reliability and peak regulation.The project with energy efficiency exceeding 70% can be regarded as natural gas peaking power stations,10 MW and below DES/CCHP is regarded as self-powered station.
