Projects

  • Design and Analysis of a Power Distribution System for a manufacturing facility

    - Modeled two variants of a design case.
    - Performed Load Calculations, Selection of components depending upon the load calculated, harmonic analysis, cost analysis and designed the layouts accordingly.
    - Simulated one Line Diagram, performed load flow analysis, shortcircuit analysis of the two variants by using ETAP. Design and layout are in compliance with NEC standards

  • Power System Stability and Control

    Power System Stability and Control with Phasor Measurement Unit and NERC Reliability Role of Frequency Response and role of inertia in frequency response for three American and Quebec Interconnections. Analyzing the effect of frequency response with primary frequency control, renewable energy penetration, generation control and with energy storage devices. Simulation is done in Power World tool and PSSE. Spring 2014

  • Analysis of symmetrical faults of an IEEE 14-bus system and Optimal coordination of overcurrent relay for 3 phase fault

    Designed an IEEE 14-bus system and determined the sub transient fault currents during different types of faults. Dependability check was done for a 14 bus power system and coordination was established with the fuse.Verified the results of calculation by performing computer simulation using ETAP software.

  • Design and analysis of a Solar and Micro-Hydro electric power system for powering a residential facility

    Powering off grid two level building with micro-hydro and solar power. Analyzing demand, resource assessment, selecting appropriate technologies, economics and environmental impacts. System is validated using HOMER 2 software.

  • Design and Implementation of Power Electronic Active Filters for Harmonic Suppression and Reactive Power Compensation.

    Designed a hardware circuit of an Active Power Filter which uses an inverter to inject current or voltage harmonic components to cancel the load harmonic components.Simulation of this design was performed and the results were verified by using PSCAD. Project is done in compliance with IEEE 519 standards

  • Planning and Design of a transmission line to connect a wind farm to the system

    Designing low cost 69 kV Transmission system connecting 200 MW wind farm to load centers considering losses, congestion, reliability and stability of the system. PowerWorld tool is used to validate the model.

  • Design of Renewable Distributed Generation (DG) and Storage for University at Buffalo

    In this project, we are responsible for designing DG for university at buffalo with 30 MW demand. This includes choosing right technology for generation and storage considering resource availability and budget, designing distribution network which includes choosing right transformer ratings and cables, analyzing load curve for future expansion and designing protection for the system. Project is done in compliance with IEEE 1547 standards.

  • Solar Energy- Major Alternative Energy Source

    Statistics and research proving that solar energy is going to be major alternative energy source in the future. Studied and presented CSP and PV technologies of harnessing solar energy and the challenges involved. Researched the role of policies to overcome the challenges and future prospects of solar energy as a part of academic course.

  • Transient Stability Analysis of Power System

    The project is study of transient stability of 5 bus power system for a 3-phase fault. This involves modeling of exciter and governor control system for the generators which is simulated in MATLAB using SIMPOWER SYSTEMS tool. The stability of the system is analyzed by placing fault at different locations in the power system. Thus by adding capacitor through power electronics improves the stability of the system is seen.

  • CUK converter based solar inverter.

    Objective was to maintain constant voltage across the inverter where source of power to inverter is from photovoltaic cells. Voltage from the photovoltaic cells will be fluctuating throughout the day. CUK converter is connected across PV cells to maintain constant voltage. Feedback from the output terminals will be taken to measure change in voltage which in turn changes control signal of CUK converter to maintain constant output voltage. This constant output is connected to full bridge…

    Objective was to maintain constant voltage across the inverter where source of power to inverter is from photovoltaic cells. Voltage from the photovoltaic cells will be fluctuating throughout the day. CUK converter is connected across PV cells to maintain constant voltage. Feedback from the output terminals will be taken to measure change in voltage which in turn changes control signal of CUK converter to maintain constant output voltage. This constant output is connected to full bridge inverter to get AC output for domestic purpose.

  • Autonomous forklift

    Forklift used to lift and transport materials. Objective was to make a forklift which works without driver. Various sensor placed at different parts of forklift made it driver less. We need to code it according to our work and work arena.

  • Automatic frequency control using slip ring Induction Machine

    Objective was to get desired output frequency and to maintain it constant. Here, Slip ring Induction machine is used to maintain desired frequency by controlling slip of slip ring induction machine. Feedback from output frequency is taken and compared with the desired frequency. To compensate change in frequency, slip is changed by rotating shaft of induction machine in corresponding direction and speed.
