    Impact analysis of single line to ground fault on industrial loads using typhoon hil
    (Springer Science and Business Media Deutschland GmbH, 2021) Kanna, R.R.; R, R.R.; Dominic D, D.A.
    The demand for electrical power is now increasingly growing day by day, which results in the transition of enormous power by increasing the ability of the transmission line from one location to another. As a result of the development of the structure of the power grid, detecting power system transmission line faults every year becomes a challenging task as the system becomes more complicated. Controlling and monitoring of power systems are inevitable due to the constant growth of the power system network. In order to find the correct decision, to search for any possible problems and fault conditions in a broad interconnected network, modeling and analysis of the power system have become significant. On the overhead transmission line, a fault will rise while the two or more of transmission lines touch each other. Generally, the faults in overhead transmission lines can be categorized as the line to ground fault, the line to line fault, double line to ground fault and three-phase faults. Single line ground faults mostly occur in the distribution network. The main purpose of this work is to study or explore the single line to ground fault and recognize the impact of the transmission line fault along with the industrial load under different loading conditions that is joined with transmission line according to the distance variation using Typhoon HIL. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2021.

    Efficiency analysis of dual motor powertrain with planetary gear set
    (Walter de Gruyter GmbH, 2023) Mishra, S.; Dominic D, D.A.; Mudliyar, K.; Divakar, M.
    This paper focuses on electric vehicles with dual motors combined with a planetary gear train. The combination of sun and ring motor allows for achieving higher efficiencies and satisfying power demands as compared to single motor powertrains. Primarily dual motor drive with planetary gear train is proposed and simulated with different drive cycles. Secondarily by extracting the motor efficiency maps working area of different modes, speed and efficiency are determined. Finally, an optimization algorithm was developed to automatically change speed and torque as per load demand. In this way, our work could represent a framework for improving efficiency performances and load demands of an electric vehicle. © 2022 Walter de Gruyter GmbH, Berlin/Boston.

    A Systematic Approach to Digital Control Development for Four-Phase SRM Drive Using Single Current Sensor for Medium Power Applications
    (Institute of Electrical and Electronics Engineers Inc., 2024) Ali, T.F.; Dominic D, D.A.; Prabhakaran, P.
    In the realm of medium-power high-volume applications, Switched Reluctance Motor (SRM) drives hold great advantages over other motors. However, the SRM drive must be optimized to reduce cost without compromising the performance for medium power applications. This paper presents a novel SRM drive utilizing a Miller converter-fed SRM motor with a single current sensor, offering a comprehensive control development procedure encompassing system modeling, design procedures, dynamic simulation, analysis, and experimental validation. The SRM is characterized through finite element analysis (FEA) to derive a MATLAB Simulink simulation model, and the conduction angle is optimized for drive efficiency through parametric simulation studies. The linear SRM model for control design is obtained via small signal analysis. Speed and current controllers are designed using the K-factor method, and the efficacy of the proposed drive is rigorously evaluated across various operating modes in MATLAB Simulink. Additionally, a hardware prototype is developed and the digital control algorithm is implemented on the DSP microcontroller TMS320F28379D based on the designed controllers to further assess drive performance. The results obtained validate the robustness and dynamic performance of the SRM drive across variable speed, variable torque, and constant power modes of operation. © 2013 IEEE.
