Power electronics and controller interface for a Voltage Source Converter

Abstract: The purpose of the thesis is to develop a system for a split-rotor drive and evaluatecontrollers and their internal components such as processors, communicationprotocols and execution speed for controlling magnetization currents in a hydropower station.The first part of the thesis builds the theory review and provides an introduction tothe most common processors and controllers available. The processors which wasevaluated were microprocessor, DSP and FPGA which have a high capacity andvariety of implementation possibilities. Two controllers, PLC and PAC whereevaluated, which contain some or several of the processors and have a wide variety ofinputs and outputs and support as well several communication protocols.Three different communication protocols; WLAN 802.11, Ethernet 802.3 andBluetooth 802.15.1. Evaluation was made by comparing BER, throughput, speed and implementationcomplexity. The second part of the thesis was to develop and order an interface card forconnecting power-electronics and measurements circuits for the system, based on thetheory and evaluation of the controller and communication protocols.
