Overvoltage Mitigation Techniques for PV Grid

In this case study, the authors have reviewed the conventional techniques used to mitigate the overvoltage problem and observe that they have several disadvantages. So, it is suggested a novel technique that relies on a minor modification made to the secondary windings of the distribution transformer: an extra tapping is pulled out from each of the secondary windings into a separate PV junction box which is the modified Point of Common Coupling (PCC)...

Protection System of a Grid-connected PV System

Photovoltaic (PV) generation is growing very fast to meet load demand, as its installation takes short time. In this paper, a case study of protection system of a Grid-connected PV power plant has been presented. The function and the ANSI codes for different relays have been discussed for a Line- In- Line- Out (LILO) arrangement and the protection standards in Indian scenario has been briefed... - Dr (Smt) Sasmita Behera, Dr Bibhuti Pati


After a thorough research into both sub types of vertical axis wind turbine rotors configurations, it has been decided to base turbine design on the Darrieus model. In this project modified version of Darrieus type of wind turbine is designed... - Preetham DS, Dr. M S Shashikala

Solar PV System In Educational Institute

The major requirement of electrical power in educational institutes is at day time, as major work of teaching-learning is carried out at day time. That is the plus point for the use of solar energy. Hybrid systems such as Solar-Wind, Solar-Diesel and Solar-Biomass may also be beneficial setups depending on the geographical condition... - Umesh P Pagrut, A S Sindekar
