Energy consumption of escalators in low traffic environment

Predicting the annual escalator energy consumption based on short-term measurements

“…During the research, the long-term energy measurement raw data had to be compensated against a more accurate device, as mentioned in Section 3.3. The necessity to compensate the measured energy values rose because of the high harmonic content in the electric current in low load conditions [20] and due to the, in contrast, low sampling resolution of the measuring device.…”

“…The proposed method in this article only reflects on the already installed appliances. Although combining these findings with modeling techniques for fixed-speed escalators, described in article [19], and modeling the energy consumption of escalators in low traffic environments [20], or in changing people volumes of intermittent-operating escalators [6,7] together with using the ISO standard [4], would help to calculate the energy consumption of an escalator about to be built on the site.…”

“…The more accurate the reference usage profile is, the more accurate the estimation is. Hence, we added a custom usage profile, measured in [20], that was used to simulate times of operation in various modes and provides a more accurate reflection. Fig.…”

“…Fig. 1 presents the usage profile for the case escalator, previously analyzed in [20]. Standby, reduced-speed (slow-speed) and nominal-speed modes of the escalator claim for almost 99% of the working time.…”

“…Al-Sharif, in [18] and [19], provided the motivation, basis and framework for modelling the escalator energy consumption. This became the starting point for our research resulting in the following publications: Energy consumption of escalators in low traffic environments [20], Modelling the daily energy consumption of escalators with various passenger volumes [6] and the Impact of daily passenger traffic on energy consumption of intermittentoperating escalators [7].…”
