An energy-efficient autonomous energy supply system based on an external combustion engine

Resumo

Simultaneous production of electrical and thermal energy on cogeneration plants allows to use fuel energy resources in autonomous power supply sources effectively. Application of external combustion engines, which have several advantages over other types of heat engines, is a possible way to improve cogeneration plants. Cogeneration plants based on external combustion engines represent a complex of interrelated subsystems. The main purpose of this publication is to show a possible structure of an electric subsystem. A general functional diagram of the cogeneration system and a diagram of its electrical component taking into account the features of the rotary-vane external combustion motor are presented. A permanent magnet synchronous motor and dc/dc converter are used to provide the operating modes of the energy system.
