Electric Energy Generation in Autonomous Energy Supply Module Having Rotary Expansion Engine

Abstract

<jats:p>The development of autonomous energy supply systems is among the priority ways of scientific and technological growth in the Russian Federation. The autonomous energy supply module providing the consumer with heat, electric power, hot and cold water can contain the different variants of the electric power subsystem. This paper considers three different variants of building the electric power subsystem for the rotary expansion engine used as a driving machine whereas the permanent magnet synchronous machine is used as a generator. Also the designed structure of 30 kW electric power supply subsystem is regarded.</jats:p>

Power Unit for Power Supply of an Autonomous Facility Having Ability to Connect to General Industrial Power Supply in Recuperative Microgeneration Mode

“…1 = • • -control function for operation of the local three-phase network (LTpN). The test bench allowed to carry out the studies, that confirmed the efficiency of the innovative microgeneration module system presented in the authors publications [6,9,10]. The studies carried out correlate with the data published in [11], which indicated that "one of the problems of electromechanics, which has not received a high effective solution, is the conversion of the mechanical energy of the driving shaft having the variable speed into the electrical energy with the specified quality indicators: stabilized AC voltage and frequency or stabilized DC voltage".…”

“…The rectifier-inverter unit M3 is the core of the whole power unit. It provides the generating local three-phase AC network (LTpN) and connecting sources, power receivers and energy storage via DC bus using is the boost DC/DC converter [6].…”
