Framework of Model-Based Health Optimization on the Electrical Power System

The advanced ageing of the electrical power network combined with the inevitable increase of renewable energy utilization and the constant increase of power consumption over the last decades call for a change in the current power network paradigm. Electrical world stakeholders have to embrace the situation and come up with methods of better...

Optimized Maintenance Planning for Transmission Power Systems

Nowadays, one of the major goals of electricity utilities is to optimize the maintenance of the assets which can be achieved by a more accurate condition indexing. The maintenance activities and maintenance planning of the grid included in this research is based on the condition indexing process. Several process steps included in the condition...

Effects of aging processes and varying humidity on the breakdown voltage of mineral oil in switchgear

Previous research has shown that in non-hermetically sealed medium voltage oil insulated switchgear (MV OIS), the insulating oil will absorb water from the ambient air. The humidity of oil highly influences the breakdown voltage of oil. The humidity of oil, in turn, is influenced by the acidity of oil which will change during the aging processes...

Feasibility Study of an EWICON System using the Self Adjusting Multinozzle Electrospraying Technique

This thesis describes the research which have been conducted on the self adjusting multinozzle electrospraying technique, applied in an electrostatic wind energy converter (EWICON). An EWICON system directly converts wind energy to electrical energy by the displacement of charged droplets in the opposite direction of an electric field....

The Effect of Temperature Cycling and Transients on the Dielectric Properties of Transformer Impregnated Insulation

This master’s thesis project is a part of the Sinergie project (sponsored by Agentschap NL, 2007-2012) which is dedicated to analyze the functionality of the grid of the future. The European Union has advanced plans to decarbonize the power sector onwards the year 2050 and therefore the use of renewable energy sources is expected to increase....

Modeling and investigation of the NorNed HVDC link with RTDS

Application of Statistical Life Data Analysis for Cable Joints in MV Distribution Networks: An Asset Management Approach

The greater pressure from both customers and regulators to maintain and enhance service reliability, while at the same time controlling costs, has caused many utility distribution businesses to adopt Asset Management (AM) as their framework. Therefore, AM is widely being applied in asset intensive industries around the world. Generally, AM...

Application of Wireless Sensor Networks in Power System Monitoring and Control: A Study on Wireless Channel, Interference and physical layer Issues

The Dutch electricity grid is considered one of the most reliable in the world. However in the near and far future, significant changes will occur, that will endanger its stability, reliability and safety. Introduction of an embedded wireless sensor network, to determine the state of the power system at any time, in order to cope with these...
