“DESIGN AND IMPLEMENTATION OF LOW COST DISTRIBUTION TRANSFORMER MONITORING AND CONTROLLING SYSTEM IN REMOTE AREAS USING PLC VIA GSM
vithalreddy MB
The main aim of this project is to monitor , control and record key operation indictors of a distribution transformer like load currents, voltages and temperature. Distribution transformers are one of the most important equipment in power network. Because of, the large Number of transformers distributed over a wide area in power electric systems, the data acquisition and condition Monitoring is a important issue. The main aim of this system is distribution transformer monitoring and controlling Through plc with pc interface and gsm. After interfacing the required components user has to develop one application program in embedded-c. Here controller is continuously reading the voltage, current and temperature, and display on the lcd along with the set point. Set point is saved in the external memory. If current value is crossing the set point then device will off and buzzer is on Along with the fan (dc motor). And one alert message is sent to the predefined number which is mentioned in application Program. If user wants to change the set point he has to send one predefined message format to the one particular phone Number which is placed in the gsm module. Then controller is reading that message and if it is in the valid format then it is updated to the external memory. Now control action is based on the new set point. Here set point is saved in the external. Memory so even power is gone set point will not change. The purpose of this project is to send the information to the mobile by using gsm technology about the distribution transformer operations like load currents, voltages and temperature. If there is any abnormality or an emergency situation the system sends sms (short message service) messages to designated mobile telephones .and we can access the controls from any part of the world via gsm technology. It is monitored and controlled using plc with pc interface. the plc can also control automatically if there is any failure then it will automatically control as programmed
Voice Monitored Wheel Chair Control
IJSRD Journal
People suffering from Parkinson's disease or from paralysis (paraplegia or quadriplegia) have the inability to move their limbs and other voluntary organs, they are dependent on someone's help to move around all the time and this makes them feel incapable and brings down their morale to survive. A solution to this becomes inevitably necessary in order to provide them with the necessary mobility and independence as they are inferior to nobody. The existing large scale manufactured versions of the wheelchair are either manually driven i.e. by the help another individual or hand driven. Paralyzed patients however do not have the ability to move their limbs but do possess the ability of speech which is the whole concept behind this voice driven wheelchair. The aim of this wheelchair is to provide a whole new platform of independent existence to these patients in the form a voice guided wheelchair. An implementation of the manufacture of this wheelchair on a large scale, the reduction of cost by simplicity in setting up and working. This will enable the wheelchair to be provided at an affordable price to the common man, this acted as another big driving force.
VOICE CONTROLLED ROBOT THROUGH ANDROID
Nagesh Nani
This project deals with one of the application of vehicles. In this project one moving object is developed such that it is moved as per commands given by the voice recognition module and that command is received by microcontroller using wireless communication. This project is equipped with DC motor, Voice Recognition module, ZigBee module, Micro controller along with the Power supply unit. Vehicle finds it applications in the real time.

Power System Protection from Out of range Voltage and Frequency
Bernard Oloo
The project is designed to develop a system to detect the synchronization failure of any external supply source to the power grid on sensing the abnormalities in frequency and voltage. There are several power generation units connected to the grid such as hydroelectricity, thermal, solar etc. to supply power to the load. These generating units need to supply power according to the rules of the grid. These rules involve maintaining a voltage variation within limits and also the frequency. If any deviation from the acceptable limit of the grid it is mandatory that the same feeder should automatically get disconnected from the grid which by effect is termed as islanding. This prevents in large scale brown out or black out of the grid power. So it is preferable to have a system which can warn the grid in advance so that alternate arrangements are kept on standby to avoid complete grid failure. This system is based on a microcontroller of 8051 family. The microcontroller monitors the under/over voltage being derived from a set of comparators. As the frequency of the mains supply cannot be changed, the project uses a variable frequency generator (555-timer) for changing the frequency, while a standard variac is used to vary the input voltage to test the functioning of the project. A lamp load (indicating a predictable blackout, brownout) being driven from the microcontroller in case of voltage/frequency going out of acceptable range .Further the project can be enhanced by using power electronic devices to isolate the grid from the erring supply source by sensing cycle by cycle deviation for more sophisticated means of detection. It can also be used to protect electric load from voltage and frequency beyond acceptable range.
