Abstract
The proliferation of voltage-sensitive load equipment has made the industrial processes much more vulnerable to degradation in the quality of power supply. Voltage deviations can cause severe process disruptions and result in substantial economic losses. Therefore, there are many studies on how to recover the original voltage immediately and keep it steady when voltage deviations are detected.
The purpose of the thesis is to analyze and design the Static Synchronous Compensator （STATCOM）. The proposed STATCOM comprises a 12-pulse Voltage Source Inverter（VSI） and a DC capacitor. Proportional-Integral（PI） controller are designed in order to regulate ac bus voltage and stabilize DC capacitor voltage. Both computer simulations and experiments are conducted in order to demonstrate the effectiveness of the proposed controller. MATLAB-Simulink is employed as the simulation tools in order to design proper parameters for the controller. In the experiments, PC-based Adventec PCL-1800 data acquisition cards with C language are used to achieve voltage compensation.
Results from computer simulations and experiments indicate that ac bus voltage can be regulated effectively by the proposed 12-pulse STATCOM.
