| Abstract: | Self excited static excitation system is used more and more in domestic large scale turbine generator units in recent years,and has gotten very good effect.At the same time,some new problems have arisen along with the application of new digital computer technology and high-power thyristor.As an example,SEE900/5000 SCR static excitation system imported from Siemens,Germany,the composition,performances and characteristics of this excitation system were briefly explained,and the influence of regulator channel fault and generator hydrogen signal on this excitation control system were analyzed,and existent problems of SCR device cooling were discussed.The corresponding methods for solving the problems are presented. |
