A Stirling Micro Cogenerator Emulator

The simultaneous production of heat and power at a small-scale is already a well known technique. Cogeneration is one of the main ways to bring about decentralised, embedded, localised and/or autonomous power production. However, it is still a challenge to design cogenerators to be below 10 kW as required for the smallest applications such as providing heat and power to a single house. This paper specifically introduces an autonomous Stirling cogeneration system for which nominal power is around 1 kW. The system is composed of a Stirling engine and a linear induction generator. In this paper, a rotating emulator is developed to study the energetic viability of the cogenerator. First of all, the system is described, then, an emulator is designed, and finally, the energetic performances of the emulator are compared with the theory
