  • System and method for controlling PCS voltage and frequency
    Patent number: 9484833
    Abstract: The present invention discloses a system and a method for controlling PCS voltage and frequency, wherein the system comprises a reference voltage converter, a phase-locked loop, a grid-side voltage converter, a voltage transformer, a first proportional integral controller, a second proportional integral controller, a coordinate converter and a SVPWM generator; a reference voltage converter is connected to an output terminal of a the phase-locked loop, and the output terminal of the phase-locked loop is further connected to a grid-side voltage converter; the grid-side voltage converter is connected to a high-voltage side of an isolating transformer of the electric grid via the voltage transformer; two output terminals of the grid-side voltage converter are respectively connected to the coordinate converter via two proportional integral controllers; an output terminal of the coordinate converter is connected to the SVPWM generator; an output terminal of the SVPWM generator is connected to a power switch of the
