Station of energy integrated: production of permanent electricity high quality and safety, for the supply of electrical systems sensitive to disturbances

摘要

A high-speed alternator (2), driven directly by a gas turbine (1), forms a set with low inertia for rapid start-up and free of low frequency vibration. Sound deadening is also provided if necessary. The alternator operates in synchronous motor mode for starting, supplied by inverter (3) from a 240v or higher voltage DC source. Thereafter, alternator output is fed via a rectifier (4) to a high voltage DC busbar (5) that also receives inputs from a battery (8) (the initial stand-by source) and a mains-fed rectifier (10), (normally used to supply the load and charge the battery). The load to be supplied is connected to the DC busbar via a power inverter (6). Mains failure, or unacceptable quality, is detected by an electronic controller, which initiates the turbo-alternator start-up sequence. When up to speed, the alternator mode evolves to generation, and the machine assumes responsibility for the load, as well as charging the battery. The controller returns the equipment to its stand-by function once the mains supply, after a period of verification, again becomes acceptable. Availability is maintained by monitoring and surveillance, effected remotely or using a portable PC.
