dc.description.abstractThis Master of Applied Science thesis presents an inverter control system design and implementation with active damping of LCL filter resonance for a single phase grid-connected Distributed Power Generation (DPGS). The focus of the thesis is to actively damp the LCL filter resonance while keeping inverter control variables well regulated. The mathematical model of the LCL filter is analyzed and the filter is designed. Then, a PLL, and a PI compensator in the synchronous reference frame, and a PR compensator in stationary reference frame along a notch filter in cascade are designed and implemented. System level simulation and implementation are conducted. The idea of systematic applying the low loss power conversion topology, effective grid condition detection, grid synchronization, and advanced signal processing theory provides some advantages for single phase grid-connected inverter control design to meet the standard specifications of the interaction between the DPGS and utility grid.en
dc.description.restricted-thesisI developed some signal processing algorithms adding to the control system, which is superior to the conventional method. I also made some contributions to system design and implementation, which make the system THD of the current injecting to grid going down 0.2% compare to conventional method. A refereed paper based on this dissertation is already accepted for presentation and will be published at IEEE Industrial Electronics Conference (IECON2014). But before that, I am revising the paper and will submit the paper and make it publish as a Journal papers at IEEE Transition. Another reason for restriction is the commercial interest. I may later apply some patents based on the dissertation.en
