AUTONOMOUS GAS FUEL MICRO-TPP USING A FREE PISTON STIRLING ENGINE Russian patent published in 2018 - IPC F02G1/45 F02B71/04 H02K35/02 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of heat and power engineering and is intended to meet the heat and power requirements in industrial and residential premises in the absence of mains power supply. Summary of invention is that the device includes an electrogenerating device (18) module, which includes the Stirling engine (1), the main gas burner (2) to supply thermal energy to the engine head (1), a synchronous linear generator with permanent magnets (3), integrated into the motor housing (1), tuning resonance capacitance (11) at the linear generator (3) output and the engine (1) cooling system (10); converting power electronics (19) module, which includes an inverter (5), a rectifier (7), an electrical energy accumulator (4) and the common AC bus (6) to which the power generating device module (18) tuning capacitance (11) is connected; heat generating device module (20) comprising a heat generator (12), an additional gas burner (13) and an emergency cooler (14); module of adjustable ballast load (9) connected to the common AC bus (6) of the converting power electronics (19) module; automatic control system (17), which signals provide control over the above modules (18), (19), (20), (9) configured to monitor the current and voltage of the linear generator (3), Stirling engine (1) thermal head temperature and control over the activation of the linear generator (3) in a function of the Stirling engine (1) thermal head temperature regime.

EFFECT: technical result is an increase in the installation reliability and efficiency by improving the system dynamic stability under transient conditions that arise when electric or thermal loads surges, and also increasing the efficiency.
