Controlling a turbogenerator during a grid disturbance

摘要

A turbogenerator system is controlled during a grid disturbance and a power electronics circuit of the turbogenerator system is deactivated. The apparatus comprises a monitor 48 including a first sensing device 74 operable to detect a condition of the turbogenerator and a second sensing device 78 operable to detect a condition of the grid, and a brake controller 40 responsive to a turbogenerator detection output from the first sensing device to issue a first brake control signal for operating a brake circuit to prevent the turbogenerator from accelerating uncontrollably and a second brake control signal for operating the brake circuit to permit resumption of normal operation of the turbogenerator. The apparatus also comprises a trigger circuit 80 responsive to a grid detection output from the second sensing device indicating a cessation of the grid disturbance to reactivate the power electronics unit and begin exporting power to the grid.
