摘　　要：以热电联产区域供热系统的一次能源相对节能率最大作为目标函数,提出一种新的最佳热化系数计算方法,并针对凝汽供热两用型热电联产机组建立了数学模型。与基于节煤量的热化系数优化模型相比,一次能源相对节能率方法不涉及热电联产机组发电煤耗率和供热煤耗率两个有争议的参数,而且所需参数的热力学意义更加明确,便于实际计算。Taking the maximum relative primary energy saving rate as the objective function, proposes a new calculating method for the optimal thermalization coefficient, and establishes a mathematical model for dual-condensable gas heating and cogeneration units. Compared with the conventional method which based on coal savings, the relative primary energy saving method does not involve the coal consumption for heating and generation of combined heating and power plants which is controversial, and the parameters used in relative primary energy saving method are more seasonable on thermodynamics and easier to use in practice.
