An approach for saving energy consumption of the electric submersible motor (ESM) has been proposed based on combining the thermal field model with electrical control. For decreasing the high energy consumption that has become increasingly serious in oil fields, one of our works is to increase the identification accuracy of the ESM temperature by overcoming the influence of the long cable. The thermal...
Because of the wind speed change, the weak magnetic of turbine and the hysteresis of the converter, wind turbines may cause voltage fluctuation, voltage drop and other instabilities on PCC(point of common coupling). An eliminating technology is urgently to be developed. Feed forward decoupling method will be used in this paper to design the controlling system with a current inner-loop and a voltage...
A control strategy for TSVG is proposed in this paper, which is a kind of hybrid static var generator (SVG), based on Active disturbance rejection controller (ADRC) theory. TSVG is a parallel topology between thyristor switch filter (TSF) and SVG, and integrates the good features of reactive power compensation and harmonic suppression together. In order to improve the performance of SVG, a controller...
