Automatic Voltage Control for East China Grid UHV AC Transmission System and Its Application
The three-level automatic voltage control (AVC) system has been established for East China Grid UHV AC transmission system.According to the structure and operaton modes,the UHVAC grid is divided into several two-level voltage control partitions.The control system and partitioning structure could meet the upper/lower voltage limt of the busbar as well as the requirements of the reactive power interchange.The actual operation case of the AVC system proves that the 500kV power plants near the UHVAC grid have enough reactive power margins,and the reactive power outputs of the generators are balanced.
