OPTIMISATION OF ELECTRIC POWER CONSUMPTION AT MAINTENANCE OF AGRICULTURAL BIOLOGICAL OBJECTS Russian patent published in 2014 - IPC G01R11/00 

FIELD: power engineering.

SUBSTANCE: invention relates to electric power engineering. This method involves determination of power costs for engineering processes, for sum of said processes, for engineering module, for shop and for the entire enterprise. Setup of power consumption costs bottom-up, i.e. from engineering process to the sum of processes, to engineering module, to shop and to enterprise. Base indices are selected at maintenance of biological structures of processes of illumination, ventilation and conveying hardware. Note here that electric power consumption for illumination is defined with allowance for illuminator specific light flux is related to unit power L₁. Electric power consumption for ventilation is defined with allowance for used air exchange themes and the type of vent equipment for air feed and removal k_A, specific costs of power consumption for feed and removal one cubic metre of air p_iA. Note here that electric power consumption for working of conveying devices is defined with allowance for consumed power of unit p_icon, power consumption for engineering module or shop is defined as the sum of power consumption for processes incorporated with engineering module or shop.

EFFECT: higher accuracy of determination.
