摘要
为应对高比例可再生能源并网带来的电力系统灵活性挑战,燃煤机组承担深度调峰任务成为常态。以典型燃煤机组为对象,系统分析深度调峰运行特性,从热力系统响应、设备风险及排放变化等方面进行建模与实验验证,在此基础上提出以控制优化、燃烧调整与辅助系统协同为核心的综合优化策略,并在实际工程中开展案例应用。研究结果表明,该策略可有效提升机组调峰深度与运行稳定性,为燃煤机组在新能源背景下的灵活运行提供理论依据与实践路径。
To cope with the flexibility challenges brought by the high proportion of renewable energy grid integration in the power system,coal-fired units have become the norm to undertake deep peak shaving tasks.Taking typical coal-fired units as the object,the deep peak shaving operation characteristics are systematically analyzed,and modeling and experimental verification are carried out from the aspects of thermal system response,equipment risk,and emission changes.Based on this,a comprehensive optimization strategy with control optimization,combustion adjustment,and auxiliary system coordination as the core is proposed,and case applications are carried out in practical engineering.The research results indicate that this strategy can effectively improve the peak shaving depth and operational stability of the unit,providing theoretical basis and practical path for the flexible operation of coal-fired units in the context of new energy.
