大火电机组在减排上有其自身独特的优势,但从动态测算和火电年龄的结构衡量,片面追求大机组可能造成适得其反的效果。我国的电力系统结构经历了从火电主导到火、水主导,进而多种电源快速发展的阶段。最近10年,在电荒缓解之后,机组容量偏小、效率偏低的问题日益暴露。2004年,国家发改委出台了新建燃煤电站的技术标准,要求新建火电单机容量原则上应为60万千瓦及以上,发电煤耗要控制在286克标准煤/千瓦时以下,从而
Large thermal power units have their own unique advantages in emission reduction, but from the dynamic measurement and thermal power age structure, one-sided pursuit of large units may cause counterproductive results. China’s power system structure has experienced from the thermal power led to fire, water dominated, and then a variety of power supply rapid development stage. In the recent 10 years, the issue of low unit capacity and low efficiency has been increasingly exposed after the electricity shortage has been alleviated. In 2004, the National Development and Reform Commission promulgated the technical standards for newly-built coal-fired power plants, requiring that the unit capacity of newly-built thermal power units should be 600,000 kilowatts and above in principle and the coal consumption of power generation should be controlled below 286 grams of standard coal / kilowatt hour
