MICRO-TURBINE GENERATOR SYSTEM SUBMITTED BY MANAS KUMAR PADHI ELECTRICAL ELECTRONICS ENGG 0501209277 CONTENTS Introduction Classification Technical Background Operation Modes Machine Performance Test Criteria Applications of MTG Merits and Demerits Future Potential Developments Vendors of MTG References INTRODUCTION Microturbine generator systems are considered as distributed energy resources which are interfaced with the electric power distribution system. They are most suitable for small to medium-sized commercial and industrial loads. The microturbine provides input mechanical energy for the generator system, which is converted by the generator to electrical energy. The generator nominal frequency is usually in the range of 1.4-4 kHz. This frequency is converted to the supply frequency of 50 Hz by a converter .The electrical energy, passing through the transformer, is delivered to the distribution system and the local load. A mathematical model of a microturbine generator system includes electromechanical sub-system, power electronic converter, filters, interface transformer, local load, distribution system, turbine-generator control and converter control. CLASSIFICATION RECUPERETED MT UNRECUPERETED MT Recuperated microturbines , which recover the heat from the exhaust gas to boost the temperature of combustion and increase the efficiency. Unrecuperated (or simple cycle) microturbines, which have lower efficiencies, but also lower capital costs. RECUPERETED MT TECHNICAL BACKGROUND MTG ‘s are small, high speed power plants that usually include the turbine, compressor, generator and power electronics to deliver the power to the grid. These small p
