A strategy of load distribution in the whole power plant based on economic operation of the auxiliary equipments in the critical load district with preferential level has been put forward

and a specialist system of load distribution based on economic operation of the auxiliary equipments being estabished

solving properly the problem of economic operation for auxiliary equipments during the time of load distribution.The algorithm of said specialist system is simple

avoiding the defect of traditional method

i.e.unduly depend on the coal-consumption characteristic curves

the result of load distribution is accurate.
