    Gsm based real time device control and electrical data logger
    (UMT.Lahore, 2014) M Nabeel Asim; Abrar Hussain; M Naeem Sohail; Syed M Fahad Wasti
    The motivation for doing this project comes from the fact that the private sector have been selling very costly protection systems to the government sector. For the sake of solution, we have designed protection module, ensuring complete security and cost effectiveness. This module monitors the voltage, current and temperature and trips the circuit under any abnormal condition. The input to this module has been taken through the CT and PT in the form of reduced replica. LM-35is the temperature sensor which will provide the value of temperature. These analogue values are scaled through RC circuit and fed to the PIC (18 F452) microcontroller where the inbuilt ADC convert them into digital form. These values are then compared with the specified values and the signal is generated accordingly. The values are displayed on the LCD. The key feature of this module is the two way communication with the remote responsible personal through GSM. When the fault occurs, the fault information will be immediately sent to the remote personal. If he wants to restore the system he can send the restoring command via SMS and the system will be restored. This module also sends the information on website after specific period continuously. So, we can access the system record from anywhere through internet.

    Laboratory emulation of wind turbine Operation
    (UMT.Lahore, 2019) Abrar Hussain; Haseeb Amjad; Hafiz Muhammad Saad Masood
    The world is paying attention towards the renewable resources to solve their problem related to the polluted environment and electricity short falls. There are many alternatives available but among all the most attractive option is wind energy. It is very important for the students that they have knowledge of practical situation. However, it is quite difficult to perform the laboratory type experiments at the wind farms. From this, there arises the need of wind turbine emulators that can emulates the characteristics of real wind turbines. This thesis explains a laboratory type emulator that is developed using DC. motor and Arduino Mega. The developed emulator can be used for the testing of real time control situations. In this emulator there is a single phase DC motor that is coupled to the single phase DC. generator. The modelling of wind turbine is done in Arduino Mega and Arduino mega is interfaced with the DC. motor control circuit using serial communication via USB. The armature current is regulated by armature voltage control with appropriate switching signal for a power MOSFET-based control circuit. The learning outcome of this emulator is to study the wind turbine characteristics in the absence of real wind turbine. Keywords DC motor, Arduino Mega.
