摘要
机组全高位布置在世界范围属于新型布置形式,以国内某台全高位布置超超临界汽轮机组为研究对象,介绍了全高位布置汽轮机组的特点,建立基于单机无穷大系统的机组及其调速系统电力系统稳定性分析实测模型,提出基于功率响应的容积时间常数辨识方法、基于阀位输入-主蒸汽压力输出的锅炉模型参数辨识方法,分析了全高位布置机组异于常规布置机组的参数特性,为同型机组调频控制策略的优化提供了依据。
Full high level layout of turbine generator unit is new arrangement form in the world.This paper introduces the characteristics of a domestic ultra-supercritical steam turbine unit with full high level layout,and establishes a test model for power system stability analysis of the unit and its speed regulation system based on single-machine infinite bus system.Then,the identification method of volume time constant based on power response and the identification method of boiler model parameters based on valve position input-main steam pressure output arc proposed,and the parameter characteristics of full high-level unit arc analyzed,which arc different from those of conventional units,providing a basis for the optimization of frequency modulation control strategy of the same type units.
