DESIGN AND IMPLEMENTATION OF A CURRENT SOURCE CONVERTER BASED ACTIVE POWER FILTER FOR MEDIUM VOLTAGE APPLICATIONS

This research work is devoted to the design, development and implementation of a Current Source Converter (CSC) based Active Power Filter (APF) for Medium Voltage (MV) applications. A new approach has been proposed to the design of the CSC based APF for reducing the converter kVA rating considerably. This design approach is called the Selective Harmonic Amplification Method (SHAM), and is based on the amplification of some selected harmonic current components of the CSC by the input filter, and the CSC control system, which is specifically designed for this purpose. The proposed SHAM has been implemented on the first industrial CSC based APF for the elimination of 11th and 13th current harmonics of 12-pulse rectifiers fed from Medium Voltage (MV) underground cables in order to comply with IEEE Std. 519-1992. 450 kVA rated APF with only 205 kVA CSC rating has been connected to the MV bus via a coupling transformer of 1600kVA, 34.5/1.1 kV. The power stage of the CSC based APF is composed of water-cooled high voltage IGBT and diode modules. Reference currents to be generated by the CSC are obtained by the use of a selective ha harmonic component. An Active damping method is also used to suppress the oscillations around the natural frequency of the input filter, excluding the harmonic components to be eliminated by APF. Simulation and field test results have shown that SHAM can successfully be applied to a CSC based APF for reduction of converter kVA rating, thus making it a cost-competitive alternative to voltage source converter based APFs traditionally used in industry applications.

Model Predictive Control of Power Electronics Converter - Jiaying Wang - Master of Science in Electric Power Engineering Norwegian University of Science and Technology

Abstract
 Voltage-source PWM (Pulse Width Modulation) rectifier can provide constant DC bus voltage and suppress harmonic distortion of grid-side currents. It also has power feedback capability and has a broad prospect in the field of DC power supply [1], reactive power compensation, active filtering and motor control system. This dissertation studies the theory and implementation of PWM rectifier and completes the following tasks: 1. Analyze three-phase voltage-source PWM rectifier (VSR), including its topology, mathematical model and principle. Derive Clarke transformation and Park transformation and analyze the mathematical model in the two-phase αβ stationary coordinate and dq rotating coordinate. 2. Make a detailed analysis on the principle and characteristics of Direct Power Control (DPC) strategy and Model Predictive Control (MPC) strategy and study the instantaneous active power and reactive power flow in the rectifier. 3. Based on the principle of traditional switching table of DPC, an improved table is proposed. Then this project presents a further improved switching table to achieve better control performance and the simulation model in Matlab/Simulink environment is established to verify the algorithm of voltage-oriented direct power control strategy. 4. Based on different strategy studies and the simulation results from DPC system, propose our model predictive control (MPC) algorithm. 5. Analyze the modulation principle of the space vector pulse width modulation (SVPWM). 6. Build the MPC-SVPWM model in Matlab/Simulink to verify our MPC algorithm. 7. The simulation result shows that MPC-SVPWM performs better in harmonic suppression, unity power factor, DC output voltage ripple coefficient and dynamic response than DPC. Key words: PWM rectifier, unity power factor, direct power control, model predictive control,
