A204 DEVELOPMENT OF A 150kW MICROTURBINE SYSTEM

概要

論文の詳細を見る
A prototype machine for a microturbine system using a simple humid air turbine system (electrical output : 150 kW; electrical efficiency : 35% LHV) was integrated for its laboratory evaluation. Systemdesign, main components and auxiliary components are described in the paper. One feature of the microturbine is to utilize water to improve the electrical efficiency and lubrication of bearings. Component tests were successful. Low NOx emission under 10 ppm was achieved at the rated load condition and sensorless drive of the permanent magnet generator controlled by the power conversion system was applied for starting operation of the microturbine system. The integrated machine is currently undergoing a motoring test to confirm its stable rotation and to check characteristics of the compressor. Design values for the compressor have shown good agreement with experimental results in the motoring test.
