Space Vector Pwm Control Technique for Three Phase Voltage Source Converter

In this Space Vector PWM Control technique is designed for a three-phase voltage source converter (VSC) which act as a Static Synchronous Compensators to provide reactive power compensation. The VSC as STATCOM provide efficient damping for sub synchronous resonance that enhance the Power System Stability in addition to RPC. Among different Pulse width modulation techniques SVPWM technique is implemented as it is easy to achieve digital realization and DC bus Utilization. The space vector control algorithm in VSC provides different functions such as reactive power compensation for Power factor correction, Harmonic Elimination, Load balancing for both linear and non-linear loads. The proposed method relies on an approximate third-order nonlinear model of the VSC that accounts for uncertainty in three system parameters. The design ensures asymptotic tracking of q-axis current and dc-voltage reference trajectories. Simulation and experimental results verify the performance of the controller relative to an established vector control method.
