EXPERIENCE:

TECHNICAL ANALYST – ARIZONA PUBLIC SERVICE (Via PARADIGM TECHNOLOGY, AZ) Aug 2015- PRESENT

Monitored the Remote Terminal Unit (RTU) performance in the Energy Management System (EMS) and performed quality troubleshooting on the RTU communication path by circuit path testing and loopback analysis.

Effectively performed remote operational and functional tests on RTUs and protective relays on EMS over the SCADA network.

Provided EMS technical support to Energy control center, Protection and control engineers, Protection metering/auto control team and various other departments for effective troubleshooting of SCADA network, metering, and other instrumentation failures and misoperations. INTERN - MEGATECH CONTROL, DUBAI, UAE Sep 2012

As a part of the testing team, performed tests on the operation of the SCADA system and debugged the faults efficiently.

Programmed PLCs using programming software Rslogix and Step 7. ACADEMIC PROJECTS

Planning and design of 400 KV transmission line construction [Matlab, C] Spring 2014

Successfully designed a high voltage transmission line of 130 miles including the selection of transmission line towers, insulators and conductors according to the NESC and IEC standards.

Estimated the regulation, reduced losses and identified the optimal capacitor placement for a distribution feeder at maximum and minimum load conditions.

Developed cost estimates, schedules and prepared specifications for procurement of transmission line materials and for the construction. Dynamic analysis for islanded operation of micro grid (Gas Processing site) in Saudi Arabia: [PSLF, C] Spring 2014

Executed a power flow study to evaluate generator capability and the behavior of the micro grid when disconnected from the external grid.

Successfully determined the most efficient governor setting and tripping mechanism to be implemented in the grid to meet contingency criterion for short circuit faults and generation loss using contingency analysis, transient stability analysis.

Gained experience in investigating, troubleshooting and resolving complex and unique client issues to meet contract requirement. Power flow program using sparsity programming techniques [C language] Spring 2014

Developed a program code in C language to solve the non-linear power balance equations for the IEEE 118 bus power system using industry standard sparsity programming techniques.

Minimized the overall run time by implementing Numerical (LDU) factorization, linked list structures and TINNEY ordering (for optimal ordering) methods. Power systems protection design of a radial system [Power world simulator] Fall 2013

Modeled 14 bus system representing an Arizona 230 KV transmission system in Power world Simulator.

Achieved effective protection for the system by designing and coordinating the protection schemes for the system; time over current relay for overload protection, directional relay for transmission line protection and differential relay for transformer protection in the system. Transient stability analysis of a two area system using system software [PSAT/TSAT] Fall 2013

Effectively modeled synchronous machines in a two area, four machine system using the DSA tools (PSAT/TSAT).

Performed transient stability analysis of the synchronous machines in the system and the effect of the fault location on the system transient behavior was studied based on their critical clearing time.
