OPERATION AND PROTECTION OF INDUCTION MOTOR BY USING GSM TECHNOLOGY
ABSTARCT :
Single phase and three phase induction machines are very popular in the industries because of their vast applications. Hence it becomes necessary to protect them against faults so as to ensure uninterrupted operation and functioning. Various parameter controlling and monitoring systems are present for other types of machine, but in case the of induction machine the controlling and monitoring systems are not extensively used due to high cost of installation and physical constraints. So as to overcome the limitations in monitoring and controlling, GSM Based System is used which makes it cost-effective and simple. Monitoring of voltage and current by employing GSM based system was a radical step towards automation. Different approaches have been developed, for induction motor control and parameter estimation, but only partial results were obtained. After going through this entire project it was concluded that the GSM based protection system of the induction motor is viable and can be safely implemented for the use of industrial automation.
EXISTING SYSTEM :
In Existing system induction motor has to be monitored and controlled by human to check whether the motor is running properly. In several cases running of motor may take even 24 hours, so monitoring of motor for 24 hours is impossible. In this existing scheme human monitorisation is must.
DISADVANTAGE :
Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes
PROPOSED SYSTEM :
Manual systems is used in the existing scheme and it is replaced by automation system. If there is any increase or decrease in voltage and current, the motor will be turn off. When problem occurs, it sends a message to the operator regarding to that failure with the help of GSM module.PIC microcontroller is used in this system. It acts as the heart of the kit.
ADVANTAGE :
They are found in most electronic devices such as alarm systems, computer control systems, phones, in fact almost any electronic device. Many types of PIC microcontrollers exist, although the best are probably found in the GENIE range of programmable microcontrollers. These are programmed and simulated by Circuit Wizard software.
