This paper is an attempt to provide a user friendly software package for teaching of standalone SEIG. Three operating conditions of the generator are mathematically modelled and then simulated using MATLAB commands. Active GUI window with these models are created using Graphical User Interface Capability. The requirements of capacitor bank for SEIG for its self excitation are also incorporated ...

This paper analyses the quality of electricity in railway traction. Power quality characteristics have been measured as a case study in a traction sub-station in Tamil Nadu, India, where 1400 KVAR capacitor bank is installed. The actual data has been obtained through direct supply of traction load. Harmonics and various power quality problems are generated through the load of current. The emerg...

A novel charge-based comparator and folding circuit are presented. Correlated double sampling comparison is performed using a log-domain integrator, implemented by a subthreshold MOS transistor with the source coupled to a capacitor. The circuit produces a current that is a logistic function of the change in voltage on the gate, with an input-referred offset voltage that is a logarithmic functi...

The proposed photovoltaic Micro Inverter is based on three port flyback with one port dedicated to power decoupling function so the decoupling capacitance is reduced and hence the long lifetime film capacitor is used. One of the two transformers and one capacitor is used for decoupling function. The decoupling capacitor functions as energy storage as well as snubber capacitor to recycle the tra...

Identification of fault locations in capacitor banks is still under development. Although, faults can be detected by an unbalance relay, it cannot identify the location. To address this issue, study proposes algorithm that categorize protection zones, phases, and a bank using phase angle boundary area. The result showed proposed was effective indicating Performance compared with conventional me...

Fuzzy logic based voltage controller is proposed for hybrid generation scheme using solar and wind energy for isolated applications. The fuzzy logic controller is designed to vary the duty-cycle of the DC-DC converter automatically such that to maintain the load voltage constant. The hybrid scheme comprises one set of fixed capacitor bank and a parallel connected three-phase fixed frequency pul...

An algorithm for locating faults on series-compensated transmission lines is presented. Use of two-end synchronized measurements of currents accomplished by current differential protective relays with additional incorporation of the locally measured three-phase voltage is considered. In case of double-circuit lines also providing of zero-sequence currents from the healthy parallel line is assum...

In present day's energy conveyance frameworks is experiencing serious force quality issues. These force quality issues incorporate high responsive force trouble, music momentums, burden unbalance, unreasonable unbiased current and so forth. A few solutions for these force quality issues are accounted for in the writing. A gathering of controllers together called Custom Power Devices (CPD), whic...

108 Many multifactorial diseases, such as various forms of cancer, diabetes, coronary heart disease and schizophrenia, still pose a considerable challenge for those researchers intent on understanding their causes. Some progress has been made in identifying the genes that contribute to such diseases and the availability of the sequence of the human genome holds further potential. However, scien...

A resonant type pulse power supply, for an application to a compact proton and/or heavy ion synchrotron with a several Hz repetition rate, is attractive from the view point of attaining large average beam current that is enough for the radiation therapy. Maximum ampere-turn of the dipole magnet is as large as 200 kA to make the bending radius as small as possible. Pulse current is generated by ...
