FIELD: power supply.
SUBSTANCE: invention relates to urban and industrial power supply systems, in particular, to a method of determining a complex value of total technical losses of full power in equipment of power supply systems used to transport electric energy to an end consumer. Invention makes it possible to determine complex value of technical losses of full power in equipment of power supply systems, used for transportation of electric energy to the end consumer, to assess the efficiency of their operation. Objective of the invention is to consider as a whole a set of elements of the power supply system and the load, connected by a common mode of operation, use in calculations of known running parameters of power transmission lines and nameplate data of power transformers, and synchronously measured or randomly set values of supply voltage and load.
EFFECT: high accuracy of determining total technical losses of full power in urban and industrial power supply systems.
