Multilevel Current Source Converter-Based STATCOM Suitable for Medium-Voltage Applications
Objective
The main objective of the project is to reduce total harmonic distortion and switching current losses (di/ dt).
Abstract
In this project, a new method of modulation strategy is proposed for the Multilevel Current Source Converter (MCSC) STATCOM. The new modulation method produces less THD and π πβπ π at the terminals of the MCSC STATCOM when compared to the widely used Phase-Shifted Carrier SPWM (PSCSPWM). To ensure the inductors' currents remain balanced, a Current Balancing Algorithm (CBA) is presented.
The CBA does not require any controls. It relies on assigning optimum switching states to each CSC module. In addition, two control strategies are presented in this project. The first one assumes the STATCOM to be a SISO. Therefore, it only requires one PI controller.
However, the gains for the controller must be changed if the STATCOM was to transition from capacitive mode to inductive mode, or vice versa. The second control strategy overcomes this problem by implementing a TITO integral state feedback controller.
