Protection and Change over Pump

Abstract

The Aim of this project is for protecting the Boiler Feed Pump failure and using a changeover scheme by monitoring the required parameters using pc for the continuous power generation. The existing system in Thermal Power Plants uses the hardware based input and output modules for the protection of Boiler Feed Pump. The major disadvantage of this system is more complicated hardware and many relays are employed. Therefore the changeover of one Feed Pump to another Standby Feed Pump during the emergency situation takes more delay. To overcome this serious problem, the proposed system uses the Pc for Boiler Feed Pump Protection and changeover scheme. In this proposed project the sensing devices such as pressure flow, temperature etc are connected to the ADC and the converted signal is given to the Pc through printer port for monitoring. The computer display all the parameters of Boiler Feed Pump graphically and sends a trip signal to trip the Feed Pump through specially designed fast acting drive circuits when abnormal occurs in any one parameter of Boiler Feed Pump.
