ELECTRIC POWER COMPLEX Russian patent published in 2008 - IPC H02B7/00 H02J3/04 

FIELD: electrical engineering.

SUBSTANCE: electric power complex includes cogeneration plant, external grid transformer substation and external source of heat supply, for instance, boiler plant. Cogenerators of station are connected parallel to distribution busbar of grid transformer substation without possibility for generated power overflow to external networks, and are differentially communicated to consumer objects. In normal mode of operation all consumer objects receive electric power of station cogenerators and from external electric grid, and in extreme situation cogeneration plant provides electric power to priority group of consumer objects. Every of cogenerators contains motor-generator and system of concurrent heat energy recovery. Besides, complex is arranged with the possibility of adaptation to oscillations of current demand in power and situations in external networks with change of consumed power from maximum to minimum one.

EFFECT: provision of operation reliability; higher efficiency factor.
