Moiseyev A. Electromechanical Complex Of Independent Power Supply With Turbodetender For Gas-Transport Stations.

Electromechanic and electromagnetic processes in independent supply source with turboexpander. Target of research is development, creation and research of energy and resource-saving independent supply source of electric power for gas-distributing stations (GDS ) and units (GDP) which are located on distance from electrical power lines. Analysis and synthesis, theory of electrical machine, theory of automatic control, computer modeling, theory of electric drive and physic modeling methods. There was developed cost and environmentally effective independent supply source of electric power in the form of electromechanic system "Turboexpander - induction generator - rectifier unit - pulse width converter, inverter", there was developed the calculation methodology of electromechanic complex and option of its elements, there were deduced correlations for definition in terms of complex self-oscillation capacity, taking into account active and inductive reactance of stator frame and capacity, there was created experimental electrical power equipment of electromechanic complex with capacity of turboexpander 10 кВт and ran the tests. For the first time there were scientifically well grounded building principles of energy and resource-saving independent supply source of electric power for GDS and GDP taking into account reducing gas pressure by turboexpander; calculation methodology of appliance of independent supply source of electric power with turboexpander and with induction generator which allowed to have a choice of electrical power generator and power has got further development; there were upgraded split for capacity calculation of self-oscillation induction generator taking into account work distinctive features of electromechanical system and taking into account inductance of stator frame that allowed to provide the work of induction generator in a section of small saturation by magnetic circuit.
