Presently, nonlinearity of Electrical utility leads to poor power quality due to increasing use of PE converters which results in financial loss, environmental impacts or safety concerns. It has many significant causes of poor power quality i.e., Harmonic pollution, Load imbalances resulting in voltage imbalance, Reactive power. As a consequence, Betterment of power Quality is on demand with the help...
Now-a-days, decadence of power quality is foremost issue of electrical society. In practice, utility of switching device is increased in industrial as well as in domestic applications. Non-linearity causes adverse effects on system efficiency, utility of the power supply, power factor, etc. As reduction in power factor increases reactive power which does not have any contribution in energy transfer...
Now-a-days, sustainability of power quality is a major concern. Speed control of an AC motor is required for several industrial applications, but is often difficult to achieve as the AC motor runs at fixed speed. Hence, power electronic devices are introduced in the system. Due to the development in power electronic devices with improved dependability and cheaper cost, results in the growth of modern...
This paper presents a comparison between two different approaches to fault location both with and without utilising transmission line parameters. Firstly, an impedance-based parameter-dependent algorithm, derived by using modal transformation theory and fast Fourier transform is presented. The methodology is able to locate the fault whether it is on an overhead line or on an underground power cable...
Power quality shows the fitness of electrical power system. In recent years, efforts are made to upgrade power quality. Multi pulse converters are used to achieve good quality of electrical power. Phase shift transformer is used to obtain 12 and 24 pulses as outputs. The quality of power mainly depends on some parameters like, variation in voltage magnitude, transients in voltage/current, harmonic...
