In the control system of three imported electric driving drilling rigs,the active power and reactive power exported by the generator are transformed respectively. In the RILL system, there is a diode bridge switching circuit. Its time of conducting is controlled by respective phase voltage. The conducting time of respective phase current is thus controlled and the switching circuit is made to export active power and reactive power; respectively. In the μDRILLTM 3000 system,different combinations of multiplier and adder are used to transform voltage signals which are in proportion to the generator's active power and reactive power. In the IPS system,the output signals of two multipliers which reflect the generator's different line voltage and phase current are respectively transmitted to different input terminals of two low-pass filters. The filters exports active power and reactive power respectively.
