FIELD: transport.
SUBSTANCE: invention relates to electrical power systems and can be used in elevator supply systems for continuous operation under normal operating conditions and at supply faults. Proposed is electrical power system that can be used in elevator supply systems for continuous operation under normal operating conditions and at supply faults. Regenerative drive supplies power from the main power source to winch motor in normal operating conditions. Emergency supply system comprises standby power supply to disconnect regenerative power source in case it fails and connects standby power supply to regenerative drive of winch motor tor its continuous operation.
EFFECT: simple design, lower costs.
