The project proposes a new converter for photovoltaic system which is substantially high performance oriented. Furthermore, the lack of batteries replacement water pumping systems without the use of chemicals are responsible for the failure of such systems in isolated areas. The converter is designed to drive a three-phase induction motor directly from photovoltaic system. The majority of commercial systems use low-voltage (PV) energy. The use of three-phase induction motor presents a suitable replacement of dc motor though by the use of dc motor we can directly drive by means of converter dc supply, but due to its lack of performance …

For a primary substation (P/S), there are many typical methods to control voltage and reactive power such as adjusting the generator mode, switching shunt capacitor (SC), adjusting on-load tap changer (OLTC), and switching shunt reactor (SR). In this study, a graphical user interface (GUI) is designed combining with nine-area diagram to observe the relationship between voltage and reactive power in a P/S. This GUI not only predicts the effect to dispatchers in short time but also analyzes the sensitivity parameters. Field measurement data were analyzed. Simulation results confirmed the feasibility of compensating the reactive power and adjusting voltage simultaneously.

Synchro-Phasors In Power System, Innovative Research Publications Irp India
Innovative Research Publications IRP India
The Phasor Measurement Unit (PMU) is considered to be one of the most important measuring devices in the future of power system. The difference comes from its unique ability to provide synchronized phasor measurements of voltages and currents from widely dispersed locations in an electric power grid called synchrophasor technology .In SCADA system, the measured quantities remain constant during the data gathering process. Hence the dynamic characteristics of the power system cannot be estimated. Synchrophasor technology is used to overcome this drawback. The Global Positioning Satellite(GPS) is used for synchronisation between the PMUs at different places, which receive the signal …
