HYDROGEN COOLED, 2 POLE TURBOGENERATORS - 1

HYDROGEN COOLED, 2 POLE TURBOGENERATORS PRODUCT SPECIFICATION Introduction Hydrogen cooled generators, designed to be driven by both gas turbines and steam turbines, are used extensively in thermal and nuclear power plants. The characteristics of these machines are the result of an in-depth knowledge, gained from BRUSH’s extensive experience, and the latest design techniques, backed by modern manufacturing methods and plant. To date, a total of 106 hydrogen cooled generators have been installed, providing a total of 11,250MW and establishing an enviable reputation for reliability and availability. The machine hall of Melnik II Power Station in the Czech Republic. Features Hydrogen cooled generators provide the following features: • • • • Reduced weight of active components. More economical operation, particularly under part load conditions. Improved efficiency as a result of significantly reduced ventilation losses. Extended insulation life. Specifications The machine hall of Nováky Power Station in the Slovak Republic. Voltage range: Speed: Excitation: Output range: up to 18kV 3000 rev/min for 50Hz operation 3600 rev/min for 60Hz operation Brushless or static 200 – 375MVA Hydrogen cooled generators comply fully with the provisions of the relevant international standards. The most common standards are: Installing the generator stator at Mejillones Power Station in Chile. • • • • CSN EN 60034-1+A1+A2 IEEE C50.13 at 60Hz IEC 60034-1 at 50Hz IEC 60034-3 at 50Hz Gas supply system The gas supply system, which can be “tailored” to suit the individual requirements of a power station layout, incorporates the equipment for scavenging air from the generator with carbon dioxide and for the first fill and subsequent continuous maintenance of the hydrogen coolant. A “freezing out” process achieves hydrogen drying. Inserting the rotor of a turbogenerator at Sevo Power Station in Finland.
