摘要：
A reserve power system includes a reserve power machine (2) for the generation of power. The reserve power machine (2) is connected via a distribution network (4) to consumers (10,12) and elevator drives (8). The elevator drives include an elevator hoisting motor (28) and a frequency converter (26) controlling it. The elevator drives are provided with regulating devices (26, 44, 46) by means of which the speed of the elevator motor (28) is so adjusted that the power taken by the elevator drive (8) from the distribution network (4) is lower than an adjustable power limit (P.sub.A).
