<p>In the invention an elevator system (24) and a method for controlling elevators in the elevator system are presented. The elevator system (24) is connected to the electricity distribution network (4) of the building, which can further be connected either to the public electricity distribution network (7) or to a reserve power appliance (2). The elevator system (24) comprises at least one elevator (8), an elevator control system (34), an elevator motor (28), and a frequency converter (26) fitted to supply the elevator motor (28). The elevator system can be used both when the electricity network (4) of the building is connected to the public electricity distribution network (7) and when the electricity network (4) of the building is connected to a reserve power appliance (2), and the elevator system (24) comprises means for controlling the elevator (8) such that when the electricity network (4) of the building is connected to a reserve power system (2) the power supplied by the elevator system (24) towards the electricity network does not exceed the power limit P3 that can be set for it.</p> |
