In particular, it was the practical aspects of making my own contribution that were attractive: the PhD would give me a chance to come up with a method or a design that would maybe one day be used by many people, and make their user experience much better, he continues.

Why wireless communication? This project takes a systems approach to improving the efficiency of electric vehicle induction motor traction drives. Reactive power control is recognized to have the largest flexibility potential in DNs, since it can minimize losses, mitigate voltage issues, tackle unbalances in multi-phase systems and provide voltage support to higher voltage level, comprising the cheapest active measure.

With higher penetration of renewable generation and market liberalization, operating points of electric power systems become increasingly variable and less predictable.

To ensure economically efficient and secure operation of such systems, fast and robust optimization algorithms are required. Despite considerable research efforts, the development of these algorithms remains a challenge due to the nonlinearity and high dimensionality of system models.

This dissertation focuses on the optimal power flow OPF problem, which is at the heart of techniques used in power system operation and planning. As this problem is non-convex and highly nonlinear, modern solvers cannot always find its locally optimal or even feasible point. To address this issue, an approximation of the OPF problem is proposed that helps reduce its complexity without compromising the solution quality.

Following detailed optimisation, a demonstrator machine was manufactured, which includes a skewed rotor. The performance of this machine was measured at a number of test points to verify predictions of output power, voltage and voltage harmonics.

Ganesh Balakrishnan served as his committee chair. Infrared IR detectors are an enabling technology for a broad and growing list of applications including gas detection, night vision, and space-based missile warning.

There electrical generation in phd power thesis ongoing efforts in IR detector research to explore the potential of new material systems and energy band structures in addition to continuously improving their sensitivity through increasing their quantum efficiency and lowering their dark current and noise. In this work, four long-wavelength infrared ICIP devices with one, four, six, and eight stages were characterized at varying temperatures from 80 to K and at biases up to one volt in both forward and reverse polarities.

The devices were found to cause circuit instability when operated in bias regions with negative differential conductance NDC due to bias-dependent resonant tunneling. Additionally, bias-dependent photocurrent gain was observed using illumination of the devices with nm and nm lasers which peaked near the NDC regions. This photocurrent gain was experimentally shown to be caused by current-mismatch between device stages, verifying theories regarding its origin.

Francisco German Perez Venegas Balu Santhanam served as his committee chair. Venegas' dissertation is, "Detection and classification of vibrating objects in SAR images. The vibratory response of buildings and machines contains key information that can be exploited to infer their operating conditions and to diagnose failures.

The programme combines power systems analysis with: High voltage design Network planning Simulation models for analysis of steady-state, dynamic and transient phenomena Compensation systems Application of advanced control and surveillance strategies Stability Reliability Voltage quality Relay protection. You can explore questions such as: Should the entire high voltage network be laid in cables? How should this be done?

How would the future distribution network be, including decentralised supply units? What control strategy would be required? Should the customer pay time-dependent prices to encourage adjustment of consumption patterns?

Should the distribution network be able to run independently in the future disconnected distribution electrical in phd power thesis the transmission network? Nonetheless, they can be successfully employed to recover energy from waste heat and their use has increased rapidly in recent years, with applications ranging from microwatts to kilowatts, due to energy policy legislations and increasing energy cost determined by climate change, environmental issues and availability of energy sources.

The performance of TEGs, subject to thermal and electrical effects, can vary considerably depending on the operating conditions, therefore it is necessary to measure and characterise their performance, and to understand their dynamic behaviour and interaction with the other parts of the system.

Phd thesis electrical power system

Based on this knowledge it is then desired to develop an effective electronic system able to control these devices so as to maximise the power generated and increase the overall efficiency of the system. However, TEGs are usually employed in environments with time-varying temperatures, thermal powers and electrical loads. As a consequence in most TEG systems the individual thermoelectric devices can be subject to temperature mismatch due to operating conditions.
