Project 1:
Duration: 10 months
Optimal design and techno-economic analysis of a wind generation system
An attempt has been made in this work on optimal design model for designing wind systems
employing battery banks for calculating the system optimum configurations and ensuring that the
annualized cost of the systems is minimized while satisfying the custom required loss of power supply
probability (LPSP). Required system turned out to be able to perform very well as expected throughout
the year with the battery over-discharge situations seldom occurred.
Project 2:
Duration: 4 months
Voltage stability analysis of grids connected wind generators
Wind generators can have a significant impact on the power flow, voltage profile and the power
quality for customers and electricity suppliers. This requires a suitable tool to analyze the
influence of wind generators on the distribution system. This paper presents a method to find the
steady-state voltage stability region for each bus of a distribution power system, considering the
presence of windpower generation. The maximum permissible load of each bus is calculated, so
that it can operate with the voltage within the limits allowed by the power system utilities.
Project 3:
Duration:4 months
Stability performance of a new static excitation system with boost-buck converter
The design and evaluation of a new static-excitation system for generator excitation systems to
improve the steady-state and transient stabilities. It increases or maintains the generator field
current by boosting the field voltage in the case of an input AC line voltage drop during and
immediately after a fault. The validity of the proposed excitation system is verified with computer
simulation. The simulation results of the stability analysis on the generator with the proposed
excitation system is better than that of a conventional static excitation system and a conventional AC
excitation system. Also, this proposed excitation system can be simply implemented and
controlled by modem power electronics technology.
Bachelors Project:
Duration:9months
Direct Torque Control of 5phase Induction Motor Using Space Vector Modulation
An attempt has been made in this work on an effective direct torque control for a 5phase
induction motor with sinusoidal distributed windings is developed. The torque production
component of the induction motor model, the space vector modulation can be applied to the
induction motor DTC control, resulting in considerable torque ripple reduction. Finally, with the
over all optimal switching scheme adopted, detailed simulations verify the effectiveness of the new
control.
