MAHAJAN, NIKHIL RAVINDRA. System Protection for Power Electronic Building Block Based DC Distribution Systems. (Under the direction of Mesut E Baran) The purpose of this research has been to develop an agent based protection and reconfiguration scheme for power electronic building block based (PEBB) DC distribution systems. One of the foremost applications would be in the new zonal DC distribut...

a total of 3528 specimens of freshwater turtles belonging to two families viz., geoemydidae (brown river turtle, kachuga smithi; indian saw-backed turtle, k. tecta; brahminy rrive turtle, hardella thurgi; spotted pond turtle, geoclemys hamiltonii) and trionychidae (indian soft-shell turtle, aspederates gangeticus; peacock soft-shell turtle, a.hurum; narrow-headed soft-shell turtle, chitra indic...

(Received: October 30, 2011; Accepted: December 8, 2011) Abstract: This paper presents a novel technique for transformer differential protection to prevent incorrect operation due to inrush current. The proposed method in this paper is based on time-frequency transform known as the Wavelet transform. The discrete Wavelet transform is used for analysis the differential current signals in time an...

A DC distribution system, which is suitable for access to distributed power generation and DC loads, is one of the development directions in power systems. Furthermore, it could greatly improve the energy efficiency and reduce the loss of power transportation. The huge short circuit current is always a great threat to the safety of the components, especially the capacitors and diodes. A resisti...

The Smart Grid concept introduces an updated architecture and new elements to the traditional power grid. As a result, existing survivability schemes that have been designed with a centralized architecture in mind are either inefficient or no longer applicable. In this paper, we review several solutions that have been suggested in the literature in order to ensure the proper operation of the po...

This article gives an overview of challenges in primary distribution, protections and power scalability for shipboard DC systems. Given that technology is development, several aspects systems have not yet been sufficiently devised to ensure the protection efficiency demanded. Several issues arise from lack complete relevant standardisation different regulation bodies. Unipolar bipolar bus archi...

This paper presents a distance protection test procedure by applying the Real-Time Digital Simulator (RTDS) of a power system. RTDS is a tool to design, develop, and test power-system protection. The RTDS enables real-time computation of electromagnetic phenomena with a calculation time step of even 50μs. The hardware allows the import and export of many signals from the simulator to an ext...
