Wireless Annunciator Window for Substation Application with GSM Facility

Abstract

The work aim is to understand and design of wireless communication between annunciator window and circuit breaker, relay, transformers etc., are located in switchyard for Power Substation. The wireless communication methods are more reliable, convenient and economical, faster as compared to the actual wire communication system. In our project we used a GSM system for sending wireless signal to the Annunciator window. GSM system supports to transfer the information over a long distance without use of electrical conductor or wire. It provides more flexibility and continues to play a significant role in the modernization. Using this GSM technology we get correct information on our mobile phone also. This helps when operator is long away from substation so he/she can provide control action from this place to the helper one.
