LEAD ENGINEER: KRIYANTRA TECHNOLOGIES, July 2013 - August 2016 Design and Implementation of Shunt Hybrid Active Power Filter (SHAPF): A Shunt Hybrid Power Filter (SHPF) comprising passive and active filters is designed for a distribution system as per IEC 61326 and IEEE 1052 standards. Detailed analysis has been carried before and after insertion of SHPF in the system.

Droop Control Strategy for DC Microgrid employing Super-Capacitor Energy Storage System

(SCESS): An energy management strategy is proposed for super capacitor-based energy storage system (SCESS) is proposed and simulated for an application in a DC micro grid as per IEEE 1547 and 2030 standards.

Distributed Energy Generation Using PV Panel: Conventional energy generation needs huge space and often require transmission lines to transmit energy to loads. Distributed energy generation systems can be employed easily in small spaces with fewer efforts. In this work, a photo-voltaic based generation system is designed and commissioned as per IEEE 519 and 1547 standards. ACADEMIC PROJECTS

Thesis: Development of Protective Relaying Laboratory using a Transient Analysis Program

• The goal of this thesis project is to develop a set of simulation based laboratory experiments to evaluate distribution system protection, transmission line protection, and transformer protection.

• Study the impact of high photovoltaic and wind power deployment on various protection schemes and propose and implement solutions to mitigate the adverse impacts. Auxiliary Electric System Design: The goal of this project is to design an auxiliary electric system for a combined cycle power plant based on the provided plant load list.

• Designed online diagram using AutoCAD Electrical for maximum reliability. Sized unit auxiliary transformer, station start up transformer, bus ducts, primary unit substations, secondary unit substations and motor control centers.

• Sized and selected cables and feeder conductors based on NEC and IEEE standards.

• Power flow analysis was performed to verify the voltage drops and bus voltages as per ANSI C84.1 standard.

• Circuit breakers were sized by performing ANSI short circuit analysis using SKM Power Tools.

• Protection system was designed for the entire plant that involved overcurrent relay coordination, motor protection, unit generator protection, transformer and bus differential protection. Power Systems Relaying I and II

• Determined the CT ratios and selected the appropriate time overcurrent curves for a 5-bus distribution system with an intermediate transformer.

• Calculated the phase element relay settings and performed relay coordination along with the transformer damage curve.

• Calculated zone 1, zone 2 and zone 3 mho element and quadrilateral element settings for a multi- fed transmission system.

• Analyzed the impact of mho circle expansion and contraction on fault resistance coverage for self- polarization, cross-polarization and memory polarization.

• Performed Arc Flash Analysis and selected the Personal Protective Equipment (PPE) for an industrial substation using ETAP.

Power System Planning: The project dealt with the extension of an existing power system to meet the future load demands.

• Calculated the entire load data of the given power system and the new power system for a period of 10 years.

• Performed a cost analysis of all the configurations and the most economical and reliable configuration was selected.

• Designed a 13 bus power system using PowerWorld Simulator based on the given network data and N-1 contingency analysis was performed. The final system satisfied the NERC criteria for voltage limits and line loadability.
