ABSTRACT:
A power control system is operable for controlling and balancing the generation and/or consumption of electrical power through an internal electricity distribution network connected with at least one electrically driven elevator system. The elevator system is connected to the internal electricity distribution network of a particular building, which can further be connected either to the external public electricity distribution network, or to a reserve power appliance. An elevator system includes at least one elevator, an elevator control system, an elevator motor, a frequency convertor fitted to supply the elevator motor which may be in operation when provided with electricity through an external public electricity distribution network, or during disruption of power. A reserve power appliance provides the required electricity to the elevator system, or the elevator system generates its own sustainable electricity, through active management of its power generation and consumption limits over the internal electricity distribution network.
