Generator set auxiliary steam header control method and auxiliary steam system

The invention discloses a generator set auxiliary steam header control method and an auxiliary steam system. The generator set auxiliary steam header control method comprises the steps that the load state of a generator set is obtained; a corresponding control scheme is selected according to the load state; and the auxiliary steam system is controlled according to the control scheme, so that the pressure, the temperature and the enthalpy value of a low-pressure header are within the preset range. By means of the mode, the temperature and pressure of the header can be controlled, the enthalpy value can be kept within a preset range, and therefore an engineering technology is met. 本申请公开了发电机组辅汽联箱控制方法和辅助蒸汽系统，发电机组辅汽联箱控制方法包括：获得发电机组的负荷状态；根据负荷状态选择相应的控制方案；根据控制方案对辅助蒸汽系统进行控制，以使低压联箱的压力、温度及焓值在预设范围内。通过上述方式，本申请不仅可以对联箱的温度和压力进行控制，还可以使焓值也保持在预设范围内，从而满足工程工艺。
