Enhancement of power system security using synchrophasor data

This research project investigates how to improve the security of operation of a power system using measurements taken at several locations of the power system. In the past, there was no technology available to synchronize these measured data, and thus the applications were limited. Now, the technology has advanced and the measured data can be synchronized using Global Positioning Satelittes (GPS). We investigate two different approaches for enhancing system stability and thus security.

Study on the Frequency Response of Overhead Transmission Lines

The goal of this project is to research and develop a model that is suitable for BC Hydro’s application to predict the sag of a power transmission line from its induced frequency response. Transmission lines always elongate over time due to the temperature of the conductor. The ability to monitor and obtain the shape of transmission lines is one of the most important tools in evaluating power transmission line’s effectiveness in operation, maintenance and the most important, safety.

Hydrological Simulation of the Churchill River Watershed Using Bias Corrected Climate Model Data

The goal of the proposed research project is to use bias corrected climate model output to drive a hydrological model of the Churchill River Basin in Labrador. This represents a major milestone in an existing research collaboration between Memorial University and Nalcor Energy, the primary objective of which is to determine the effects of climate change on the Lower Churchill Hydroelectric Project, to be located on the Churchill River.

Integrated Power-Management Solution for Class D Audio Amplifiers

 

This proposal targets a fully-integrated power management circuit for a high efficiency class D audio amplifier in a standard CMOS process. The project will focus on optimizing efficiency, reducing cost, and enabling wide input voltage and load current handling well-suited for battery driven applications. The converter will operate directly from a battery to provide the optimum voltage level for the audio amplifier and the proposed solutions will be able to exceed the voltage rating of the technology.
