    Control and operation of three phase synchronous microgrid
    (UMT.Lahore, 2017) Muahmmad Faizan; Yasir Ilyas; Umair Hassan; Akbar Zaheer Khan
    Control and operation of microgrid is about efficient control and monitoring. The control and operation of microgrid involves the stability of voltage and frequency at generator bus bar. This is achieved by maintaining the field excitation of synchronous generator to have 400V at the bus bar. Likewise, frequency at the bus bar is maintained at 50Hz by controlling the speed of generator. A DC shunt motor has been used, for this purpose, as a prime mover of synchronous generator. Both the speed of DC motor and field of synchronous generator are varied from DC drives. Both the drives are commanded by two Arduino separately. Emon Tx shield interfaced with Arduino is used for metering purpose at the synchronous generator output. A small resistive load box also attached at the output of generator.

    Smart vending machine modeling
    (UMT.Lahore, 2020) Muhammad Mobashir; Hamza Arshad; Umair Hassan; Muhammad Hussnain Sheikli
    Internet connectivity and JOT is nowadays very common in our modem life. Almost all of our devices are connected to the intemet like smart phones,smart watches,TV,Laptops etc.lOT gives us many possibilities for unimaginable inventions. In terms of commercial technological level Pakistani industries, we are still far away from those of well-developed coimtries. This project of ours focuses on vending machine technology. Our aim for this project was to re-model the vending machine such that it becomes affordable easily manufacturable inside Pakistan. The features we enhanced are cashless payment via RFID,Smart transactions via online database and the ability to gather user data for each individual vending machine purchase.
