Arizona State University, USA
- Master of science in Electrical Engineering specializing in power systems.
A skeleton transmission system in Arizona was modelled and power flow analysis was done to minimize the cost and to dispatch the generation in an economical manner. In addition to this, stability studies were performed to determine the compensation needed to maintain synchronism.
Software used:Power World .
A sparsity based program was created to solve the power flow problem in an IEEE 118 bus system using the Newton Raphson method. To solve this, lower, upper triangular and diagonal factorization and substitution techniques were used.
Software used: Matlab.
Modelled a sample four machine system as a classical synchronous machines and a three phase fault was applied to test the stability of this system. The critical clearing time was found and the merits of using relative angles plots were discussed.
Software used: PSLF,PSS/E.
Designed an electrical drive system comprising of a permanent magnet synchronous motor and a cascaded H -bridge inverter connected to the grid to run a 10 MW compressor. The motor was controlled using inner current and outer speed loops and also works in the field weakening region.
Software used: PLECS.
A photovoltaic system was integrated to a single phase grid using a dc -dc boost converter and a full bridge micro inverter with k factor control. The devices were switched using PWM technique and the inverter was controlled both using inner current loop and outer voltage loop.
Software used: PLECS.
Designed a single circuit transmission line from Tenkasi to Thiruvananthapuram. Determined the environmental factors, and the effects of electric and magnetic fields and calculated the number of towers,conductors,insulators.
Software Used: MatLab.
Designed an insulation system or an unmanned underwater vehicle and also analyzed the flow rates and the heat losses to maximize the operational time for a given efficiency. A finite element analysis was also conducted on the heat source to have a broader idea of the heat flow.
Software used: SolidWorks, ANSYS.
Analyzed the transmission system in Arizona and checked for n-1 contingency and found the maximum photovoltaic injection to this system without the system loosing n-1 compliancy.
Software used: PowerWorld.
Designed a protection scheme for a 230 kV transmission system including over current protection on a distribution feeder, distance relay protection, differential protection for transformer and breaker ratings.
Software Used: PowerWorld.
Studied the effect of transients on a 230 kV system and found the maximum transient voltage as well as the transient recovery voltage across the breaker and the change in it due to the effect of switching resistors.
Software Used: PSCAD,EMTP.
To certify the person is proficient in basics of Electrical Engineering.
