Abstract: Power station is regarded as the foremost dangerous place on earth, operators risk their life taking care of the facility station. The generator plays a crucial role in power plant to generate the electricity for the domestic and industrial demand for our lifestyle. It is vital to continuously monitor the temperature and therefore the voltage output of the generator all the time, so that it can be repaired immediately if it is malfunction or under critical condition. The temperature rise controller based PWM is a solution to manage all of this process automatically in a more efficient and convenient way. The purpose of this project is to build an automatic temperature rises controller based PWM system that can detect the temperature, voltage output and control the speed of the cooling fan with different PWM (0, 30, 60 and 100%) based on the range of the temperature (temp<37, 37<temp<50, temp=””>50) of the generator. The sensor used to implement voltage and temperature sensors are potential meter and LM35DZ respectively. The cooling fan is implemented by 6V DC motor. An emergency button is designed in this system to ensure that all operation of power station can stop immediately to ensure safety when emergency condition occurs. The project start withdrawing the flow chart and block diagram, then writing and generate hex file for program code in the MPLAB IDE. The circuit diagram is drawn in PROTEUS and run the simulation by load the hex file to detect the error in the circuit. After doing the simulation in PROTEUS correctly, the hex file is transfer to the microcontroller through Pit Kit 2 and the prototype of this automatic temperature rises controller is built. This system design can only indicate and show the condition of the generators on LCD, it cannot indicate the speed and condition of the cooling fan because no indicators that is design for it.
