Abstract: |
The superiority of grid voltage adjustment by the leading-phase operation of synchronous generator at low load and reactive excess is analyzed,the development of its research and the focus of each research stage are reviewed,and its main limiting factors are discussed,such as terminal temperature rise,plant auxiliary power voltage,power angle stability,field-loss protection,low excitation,etc. The research progress of its simulative analysis and dynamic model test and the application of intelligent control techniques in its research and monitoring are introduced,and it is suggested that,the coordinated leading-phase operation of multiple generators and the whole network voltage adjustment should become its new research direction under the new situation of grid development. |
