随着单机功率的增长,对自动调节系统在保证锅炉的可靠性与经济运行方面,提出了更加严格的要求。因此,在锅炉机组的自动化技术设计里提供有关动态特性的计算结果,以证实所设计的自动调节系统的功效,并掌握单元机组在过渡工况中的运行性能,是很必要的。根据确定超临界锅炉机组动态特性的分析方法,在锅炉设计阶段就可以估算对象的动态特性,以选择合理的自动调节系统。用在电子数字计算机上算出的锅炉动态特性,就可以在模拟计算机或数字计算机上对所设计的自动调节系统进行动态分析,并在宽负荷范围里对调节装置的整定与调整给
With the increase of stand-alone power, more stringent requirements have been put forward on the automatic regulation system in terms of ensuring the reliability and economical operation of the boiler. Therefore, it is necessary to provide the calculation results of the dynamic characteristics in the design of automation technology of the boiler unit to confirm the effectiveness of the designed automatic adjustment system and to master the operation performance of the unit in the transitional condition. According to the analytical method of determining the dynamic characteristics of the supercritical boiler unit, the dynamic characteristics of the object can be estimated in the boiler design stage to select a reasonable automatic adjustment system. Using the dynamic characteristics of a boiler calculated on an electronic digital computer, the designed automatic adjustment system can be dynamically analyzed on an analog computer or a digital computer and the setting and adjustment of the adjustment device over a wide range of loads can be made
