Current Source Converter

Current source converter is a variable structure system due to its switching nature, so that it can easily cause the output current waveform distortion and can not be accurately track the reference current. To solve the above problems, this paper proposes a new variable structure control strategy with fan-shaped sliding domain in the current source converter control system. In the control strategy, the paper deduces the switching surface and switching control law of SMVSC, and calculates the sliding existence domain based on the mathematical model of current source converter. Finally, the simulation results show that the control scheme can make current source converter have better output current waveform, fast tracking the reference current, and strong anti-interference ability. Therefore, the control scheme is correct, effective and feasible.

Simulation Results

The operational principle and topology of multi-level current source converter as well as its main advantages are introduced. According to the characteristics of SVG (Static Var Generator), a model of multi-level current source SVG is built up and simulated with PSCAD/EMTDC. The influences of model parameters on the performance of SVG are discussed in the form of dynamic and steady waveforms of system voltage and current. Simulation results display the feasibility of proposed control strategy and the excellent performance of multi-level current source SVG.
