Abstract

Approximately 520thousand elevators are operating now in Korea, about 40% ~ 60% of the elevator power is generated. In this paper, by using the method of adding regeneration power of the elevator to the grid-tied photo voltaic inverter, PV generation that was dependant on the solar radiation was significantly improved. In order to confirm this, the regeneration power of the elevator has been simulated in 12% of the rating load, and measured the regeneration power of the elevator in the actual condition to assess the differences of it. The 5[kW] hybrid grid-tied photo voltaic invertor has been fabricated to conduct an experiment for the confirmation of the proposing method. The effectiveness of the proposing method has been reassured with the result of experiment that include the transfer interface part of the regeneration power of the elevator.
