Research on power balance control of grid-connected generator sets of electric drilling rig

According to the configuration and load characteristics of self-contained electric power station of elec-tric drilling rig, the key elements and the control pathways which influence active power and reactive power are analyzed. The necessity of power balance of grid-connected generator sets are put forwad. The structure composi-tion of rotaional speed and voltage controller, two ideas of active power and reactive power controller, as well as the logic action programs of block diagram and controls of on-grid and off-grid are also given. The balance ideas and focus attention matters on the practical engineering application of grid-connected generator sets with different type, size and voltage are presented.
