【摘要】 超(超)临界机组不易受控,其控制策略的研究依赖于准确的数学模型。本文在研究热控领域一种常见的协调受控对象数学模型的基础上,通过分析超(超)临界直流锅炉协调控制系统被控对象的特性,提出了改进建议、给出了新的模型,并通过仿真试验的方法验证了分析的结果,为控制系统的研究提供了较为客观真实的平台。更多还原

【Abstract】 The characteristic of supercritical unit is not easily controlled,because its control strategy research relies on accurate mathematical model.Based on the study of a common coordinate mathematical model in the thermal control field,through the analysis of ultra(ultra)supercritical once-through boiler characteristics of the controlled object of coordinated control system,the paper puts forward suggestions for improvement,and gives a new model,and the analysis results are verified by digital simulation method and the model provides a convenient and practical test platform which closer to the actual objective for assessment of boiler-turbine coordinated control system.更多还原
