火电机组灵活性改造技术方案研究

Research on the Flexible Transformation Technology Scheme of Thermal Power Unit

当前,我国电力需求增速放缓,各种可再生能源快速发展。人们需要充分地挖掘燃煤机组的调峰潜力,提升我国火电机组的运行灵活性,以全面提高系统调峰和新能源消纳能力。本文针对热电机组和纯凝机组介绍了不同的灵活性改造技术方案,并从方案的可靠性、经济性等方面对各个方案进行对比分析。灵活性改造应遵循"一厂一策"的原则,结合企业自身的情况,合理选择方案。

At present, the growth rate of China′s electricity demand has slowed down, and various renewable energy sources have developed rapidly. People need to fully tap the peak-sharing potential of coal-fired units and improve the operational flexibility of China′s thermal power units in order to comprehensively improve the system′s peakshaving and new energy consumption capacity. This paper introduced different flexible retrofit technical solutions for thermal power units and pure condensing units, and compared and analyzed each option from the aspects of its reliability and economy. Flexibility transformation should follow the principle of "one factory, one policy", and rationally choose a solution based on the enterprise′s own situation.
