This Project Report On Power Grid Control System Using Gsm Modem is designed for seven electricity networks. 8051 is the centerpiece of the project. A GSM modem is interfaced to the microcontroller. This modem receives and sends messages from mobile as an input for MCU. To verify MCU to store the authentication number, and if the number is authorized, Grid Control can be achieved, EEPROM interface with this controller to the starting position at any time. This launch site information will not be erased once in power failure. 3X4-keyboard is an interface, change the phone number is, at any time. 16X2 LCD display is an interface to the users’ needs. In this project report as TraiCen load controller (as a switch), a triac MOC3021 driver.GSM use roaming facilities will be used by operators, users can often continue to use their phones when they are in other countries, used, etc. This project trips regulated 5V, 750mA power supply. 7805 and 7812 three-terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to correct the power supply from the secondary transformer 230/12V.
Nowadays there are various electronic devices for remote control of Grid Control. However, the main drawback of these systems is that they can only be operated at close range and even less reliable. So to overcome the above disadvantages, ie we are using a wireless communication technology; GSM (Global System for Mobile communications) is a digital cellular communication system, which has rapidly gained acceptance and market share worldwide. The development of GSM is the first step towards a genuine personal communication system; allow us to communicate everywhere, anytime and with anyone. GSM (Global System for Mobile Communication) is much used because of its simplicity in the transmitter and receiver design can be at 900 or 1800 MHz band to operate fast, reliable and global network.
Conclusion:
GPRS is a medium very well suited to connect small stations of any kind into a process control system. Its biggest advantage is that there is no line of any kind required to connect these stations. Although the quality is not the same as with a privately owned line, it is sufficient for many applications.
