【Abstract】 A kind of HVDC master controller based on Z-80 micro-computer is introduced. Computer-based control methods to realize constant D.C. power control, voltage-dependent current order limit(VDCOL), and HVDC start-stop control, in which rectifier and inverter are coordinated by the master controller, are presented. In addition, a new algorithm of D. C. current control based on digital P. I. and it’s realization method are discussed. The controller is tested on HVDC dynamic analog device of North China Electric Power Institute and the results are given.更多还原
