Summer Training Project Report on Real Time Clock (RTC)

The light energy from the sun is converted into electrical energy by a solar panel. The solar panel is fixed in a particular direction in ordinary solar panel systems and delivers maximum energy when it is towards the sun.

The aim of the Summer Training Project Report on Real Time Clock (RTC) is to control the solar panel according to the movement of the sun and it is accomplished on controlling the mechanical movement of solar panel by the stepper motor with the use of Microcontroller. The movement of sun from east to west has divided into segments with a fixed time frame for every segment using a Real Time Clock (RTC).

Renewable energy quickly gains importance as fossil fuel prices fluctuate. It is critical for engineering and technology students at the educational level with an understanding and appreciation of the technologies with respect to renewable energy.

One renewable energy source is solar energy. Various researches conducted to develop few methods to optimize the efficiency of Photo Voltaic systems (solar panels) and one method is a solar panel tracking system. Solar tracking generates more energy since the solar panel maintains a perpendicular to the sun’s rays.

It is estimated that tracking system is used over a fixed system to increase the power output by 30% – 60%. Design requirements are when the sun is up, the system should follow the sun’s position in the sky and it is done with an active control and must be totally automatic and simple to operate. The operator interference must be minimal and restricted when it is required.

 Summer Training Project Report on Real Time Clock (RTC) Conclusion:

This project is about a solar panel tracker which is developed to increase the amount of power generated using solar panel when the sun is in the sky. An 8051 microcontroller controls the movement of solar panel and solar panel energy is generated to charge a lead battery that acts as a supply to glow the lamp at night

Pulse Width Modulation (PWM) Btech EEE Final Document

Pulse Width Modulation (PWM) Btech EEE Final Document technique is an effective method to control the speed of induction motor. This paper is about the development of the algorithm to do the PWM operation with the help of Matlab Simulink that interfaced with the actual induction motor by Matlab/Real time workshop.

The induction motor speed was controlled by the I/O interface circuit and Simulink to allow the real time control. The control algorithm enables the rotational direction switching and these functions are carried out in Matlab simulation in actual model successfully. It is a means to control speed of induction motor by a host PC connected by local area network or wireless network.

The techniques available for the speed of induction motor are varying to change rotor resistance or terminal voltage and varying synchronous speed with change in number of poles or supply frequency. To change rotor resistance, wound-rotor induction motor is required and resistances are inserted to the rotor circuit that reduces the efficiency of the machines. The change in terminal voltage limits range of speed control.

PWM technique controls the electrical frequency of the 3-phase voltage which is supplied to the motor from the Insulated Gate Bipolar Transistors (IGBTs) inverter circuit therefore the speed is allowed to the frequency of the reference signal, input to the PWM signal generator. The Real time workshop uses in performing real-time analysis, simulation, and testing of control systems and digital signal processing (DSP) systems.

The host-target environment allows users to connect models created in Math Works design like Simulink, Matlab, and Real-Time Workshop, to physical systems, and execute in real time. The control algorithm also developed in forward or reverse direction.

Pulse Width Modulation (PWM) Btech EEE Final Document Conclusion:

The development of the algorithm performs the PWM operation using Matlab Simulink, and implementation to actual model using the Matlab/Real time workshop that controls the speed of induction motor.
