Hurkmans, Brecht (author)
In this master thesis, the design and implementation of a high-voltage switch using series-connected Metal Oxide Semiconductor Field Effect Transistors (MOSFETs) is discussed. A high-voltage switch is needed for applications such as high-voltage DC converters. Multilevel modular converters (MMCs) can also aid in the voltage-blocking capabilities...

The energy transition requires massive expansion and reinforcement of the transmission grid which is challenging because of its high utilization, and regular maintenance, replacement, and repair. The difficulty of performing maintenance on high-voltage equipment and especially the substations lies in the fact that a big part of the substation...

The penetration of power electronics into the grid is growing rapidly due to the increasing number of renewable generation systems. These power electronic converters introduce electrical stresses in the form of complex waveforms into the grid caused by their switching operations. The High voltage (HV) equipment is subjected to these stresses. To...

Medium voltage cable joints are expected to function for 30-40 years after successful installation. To optimize and improve the design of these joints, it is essential to find out the changes that the components inside a cable joint go through. In this thesis, the effects of accelerated thermal ageing on electrical and mechanical properties of...

Destructive consequences of trapped space charges within HVDC coaxial cable insulation, such as accelerated aging, degradation, and breakdown, are some of the most significant challenges that manufacturers and users usually come up with. Pulsed Electro-Acoustic (PEA) method is a widely-used method for space charge detection and measurement, in...

With the aid of the analytical formulas of the disc pair model inter-shielded by different type of shield wires, the total series capacitance of the disc pair could be calculated. After introducing a number of inter-shield pairs to the disc pair model, the influence on the mutual inductance between discs has been thoroughly discussed. Last but...

YU, GUANGYAO (author)
Power electronics technology has been widely used in industry. High-frequency harmonics caused by power electronics related products will have a huge influence on the insulation characteristics of the electrical devices. In order to study these influences, an arbitrary waveform high voltage generator is needed. The multilevel modular converter...

HVAC cable is normally installed in a PE (Polyethylene) pipe underground. The pipe is placed in the underground path formed by horizontal directional drilling (HDD). During power transmission, the generated heat from the cable is dissipated by natural convection of water in the gap between cable and pipe. In this project, the first part focuses...

Increase in demand for electric power and renewable sources of energy drives the need for more transmission & distribution capacity. When using DC, as RMS and peak voltage are the same, transferring more power can be economical but at the same time erecting new transmission lines is often associated with demanding approval procedures,...

The safety in the high voltage substations rely on the integrity of its grounding grid. A single discontinuity at any part of the grounding grid may cause a swell in touch or step potential that may expose the personnel to a hazard of critical electric shock. It may also lead to malfunction of the protection devices leading to erroneous tripping...

The shifting of the European countries, including the Netherlands, towards an electricity production dominated by renewable energy sources to be (nearly 70%) by mid-century will have a significant impact on the frequency performance of electric networks. This would cause the level of grid inertia to be considerably reduced. From this perspective...

Li, Wanlin (author)
The electricity demand is increasing with the development of industry. Nowadays, sustainable resources used for electricity generation are playing a more and more important role in the power system due to serious energy problems. Higher capability of power transmission and distribution thus becomes significantly necessary to keep the stability...

The load of the electric grid in increased by the connection of more renewable energy sources and less controlled power stations. The transmission operator has to decide where and when new overhead lines are required. However the operator can also chose to utilize existing lines more by increasing the transport capacity. This can be accomplished...
