Assessment of actual power and electric power at construction sites

Viktor Reznichenko, Valentin Demidov, Georgii Demidov

Abstract


The article deals with issues connected with power supply of buildings and structures under construction. Due to nonlinear nature of electric power consumption at building industry enterprises, current and feeding voltage are distorted. This causes additional losses of actual power and energy, as well as inaccuracy and ambiguity in readings of power control devices and electric power metering. The article generalizes results of research on harmonic composition of electric power parameters of static converters and states recommendations on improvement of assessment and accounting of actual power and electric energy in electrical networks of building organizations.

Keywords


actual power, electric power, unsinusoidality, higher-order harmonic, idle-current wattmeter, electric power meter
