Research of Elevator Loads of Apartment Buildings

This article presents the results of the research of elevator loads of two apartment buildings (Moscow, Russia). The initial data were obtained by taking half-hour readings of active electricity from the electricity metering devices installed on the introductory switchgear of the apartment buildings. Based on the initial data the values of household and elevator loads were obtained, daily load schedules of apartments and elevators were constructed separately. As a result, coefficients of the elevator load participation in the maximum load of apartments as well as the demand coefficients of the elevator load of both buildings were determined. Finally, a comparison was made of the obtained coefficients with the normative values from standards used in the design of urban power supply systems.
