Turbo-generators can be subjected to negatively damped subsynchronous frequency oscillations caused by the interactions between the generator and the external network. This phenomena is termed as subsynchronous resonance(SSR) and it is well known that series compensated ac lines are the major contributors. In recent years, it has been established that HVDC systems with converter controllers can...

Wind power development is booming globally, and large scale onshore wind power is under development in China, the Americas and India. Compared with AC transmission, HVDC technology can due to lower losses be attractive if the distance from generation to consumption is long. VSC (Voltage Source Converter) HVDC is rapidly maturing as a technology, and offers some significant advantages compared t...

In the present scenario, the increasing penetration of solar energy can be significant challenge due to the variation of power generation. One of the solution to improve the quality of power supply and guarantee of system stability is energy storage system(ESS). In this project, a AC-DC hybrid micro grid is designed based on photovoltaic (PV), generator and energy storage system are coordinated...

Such methods as droop method, curve shifting method and master-slave were primarily developed for voltage frequency regulation in isolated power systems with synchronous generators. In modern induction generators, regulated dump loads, energy storage devices AC/DC AC/DC/AC converters, etc. are used addition to The investigation of new configurations is closely tied further development control l...

This thesis first proposes a hybrid ac/dc micro-grid and its coordination control for reducing the processes of multiple conversions in an individual ac or dc grid. Renewable energy based distributed generators (DGs) play a dominant role in electricity production, with the increase in the global warming. Distributed generation based on wind, solar energy, biomass, mini-hydro along with use of f...

Two experiments examine speed-up in argument pairs of various propositional forms. In the first experiment, participants were presented with pairs of conditional arguments. Some of these pairs had a form of a valid Modus Ponens (MP) inference, whereas other pairs had a form of a fallacy of Affirming the Consequent (AC). In both argument pairs, presentation of the prime led to a significant spee...

Matrix converter is a single-stage converter which directly connects a three-phase voltage source to a three-phase load without dc-link components. Therefore, any harmonic distortion and imbalance in input voltage directly reflect to the output of the converter. Recently, many researchers have made an effort to cope with this problem. In this paper, under distorted input voltage conditions, beh...

Randomly selected generator bars from a 50-year-old Norwegian hydro power were examined in this work. Typical non-destructive tests, as partial discharge and dissipation factor measurements initially performed at both 50 Hz 0.1 Hz. Then, the AC breakdown strength of epoxy/mica/glass fibre reinforced bar insulation was measured by gradually increasing voltage steps 5 kV with duration 1 min until...
