Abstract

The invention discloses a based single pumping heat supply unit heat and power load allocation method based on characteristic coefficients. The lowest heat load and the lowest power load of each unit are taken and used, and the initial heat load and the initial power load of each unit are calculated. The total heat load and total power load are taken and used; the highest heat load, the highest power load and the characteristic coefficients are taken and used; the allocation results of the heat load and the power load of each unit are calculated; then whether the allocation results of the units meet constraint conditions one by one is judged; if each unit meets the allocation result, the allocation result is the finnal result. If one unit does not meet the constraint condition, circulation adjustment is performed till the allocation condition of each unit meets the constraint condition. The method can obtain heat supply unit heat and power load optimization allocation coincident with the traditional linear layout, and the method is simple and convenient for field application.

Description
