Abstract

The invention discloses a method, device, equipment and medium for increasing the output range of a generator, and the method is applied to a high-back-pressure heat supply unit and comprises the steps that the output range of the generator of the high-back-pressure heat supply unit is obtained; based on the corresponding relation between the generator output range and the number of cut-off heaters, the number of cut-off heaters is determined according to the generator output range; and the high-back-pressure heat supply unit is controlled to work after the corresponding number of heaters are cut off. Under the same load of the boiler, the output and heat supply capacities of the generator are enhanced, the output range of the generator of the unit is further increased, the output of the unit has wide variation capacity and range, and the demand of power generation is better met.

Description

technical field [0001] The present invention relates to the technical field of generator output control, in particular to a method, device, equipment and medium for increasing the output range of a generator. Background technique [0002] The back pressure unit is a generator unit that adjusts the power generation load by thermal load. The purpose of high back pressure heating is to increase the heating capacity of the unit, and at the same time to achieve cogeneration, effectively use the high-potential energy of steam to generate electricity, and provide heat with low-potential energy, reduce the loss of cold source to zero, and improve the thermal efficiency of the unit. Due to the increase of back pressure, the maximum output of the generator set is limited; on the other hand, in order to adhere to the principle of determining electricity by heat and improve the heating capacity of the set, the boiler evaporation cannot be reduced too low, which leads to the minimum outp...
