Doctor of Philosophy<br>Department of Electrical and Computer Engineering<br>Behrooz Mirafzal<br>In this dissertation, a new topology for Direct-Drive Wind Turbines (DDWTs) with a new power electronics interface and a low-voltage generator design is presented. In the presented power electronics interface, the grid - side converter is replaced by a boost Current Source Inverter (CSI) which eliminates the required dc-bus capacitors resulting in an increase in the lifetime of DDWTs. The inherently required dc-link inductor for this topology is eliminated by utilizing the inductance of the Permane

Then, a DC/AC power inverter is adopted for grid connection. Moreover, a Texas Instruments (TI) TMS320F2812 digital signal controller is used to implement the field-oriented controller for the three-phase power converter and inverter. Furthermore, the variable -frequency and variable-voltage electric power generated by the PMSG is converted to a stable AC-source vo

Abstract:
This research investigates the control of low-cost power electronic converters for small-scale wind turbines under standalone applications. The system utilizes a surface permanent magnet (SPM) generator operating with a semi-bridge switched-mode rectifier (SMR) into a DC voltage load. Conventional control of a semi-bridge SMR results in lower output power than an inverter (i.e. fully-controlled voltage source rectifier) due to the SMR’s inability to control its input power factor. Phase-advance modulation was introduced by Rivas et al. as a method of generating increased output power from a se

In this dissertation, a high-frequency (HF) transformer isolated grid-connected power converter system with battery backup function is proposed for a small-scale wind generation system (less than 100 kW) using permanent magnet synchronous generator (PMSG). The system includes a main HF isolated DC/AC grid-connected converter and a bidirectional HF isolated DC/DC converter. Through literature survey and some comparative studies, a HF isolated DC/DC converter followed by a line connected inverter (LCI) is chosen as the grid-connected scheme.

The dynamic nature of Mho characteristic, which happens to be most primitive technique in line protection implemented with distance relaying, is built by using the measurement of local voltage and current signals. These signals have been influenced substantially by fault resistance and the source impedance feeding the line. In case of different generation sources, the source impedance and fault characteristic also change accordingly. Environmental benefit of wind turbine technology is making it a
