<p>PURPOSE:To diminish the current capacity of a cyclo-converter, dy adding bias to a control reference value, when the value of an integrated deviation between the output current of the cyclo-converter of each phase and a set value exceeds a previously set value. CONSTITUTION:The primary winding of a generator-motor 1 is connected to a power apparatus, and to a secondary winding, three-phase AC exciting current is fed via a transformer 4, and a cyclo-converter 3. The input of the terminal voltage signal of the primary winding of the generator-motor 1, current signal, the current signal of the secondary winding, and the position signal of a rotor, to a controller 5 is provided, and according to the control reference value of terminal voltage, the control reference value of reactive power, the control reference value of active power, and the control reference value of a rotor speed, the cyclo-converter 3 is controlled. In this case, when the integrated value of an integrated deviation between the output current of the cyclo- converter 3 and an integrated reference value comes to a previously set value, then bias is added to the control reference values, and the current of the cyclo- converter 3 is reduced.</p> |
