As an important part of the generator, excitation system is an important means to improve the stability of the power system, parallel units. Mainly include the FWL microcomputer excitation system series products. FWL microcomputer excitation system is at the basis of summarizing the past experience of excitation system is successfully put into operation on the overall reliability of the developed, functional and practical perfect unity of a new generation of generator excitation system.
FWL excitation system has the maximum capacity of 1000 mw thermal power unit, the maximum capacity of 700 mw hydro unit, pumped storage units, gas turbine generating unit, such as compressors unit had a successful application.
FWL microcomputer excitation system based on independent innovation, in the industry, and to the world. Until the end of 2012, south field at home and abroad more than 1800 sets of all available capacity of the unit. Of which more than 300 sets of 300 mw grade unit of 600 mw class units more than 100 sets, 10 sets of 1000 mw, and the system has been in JHARSUGUDA Perawang, Indonesia, India, Saudi Arabia, and other foreign successful application in the project.
According to different field unit capacity and parameter, the design of configuration to make the most appropriate choice, so different units have different configuration of products.
