Micro turbines are becoming widespread for distributed power and combined heat and power applications. They are one of the most promising technologies for powering hybrid electric vehicles. They range from hand held units producing less than a kilowatt, to commercial sized systems that produce tens or hundreds of kilowatts.Part of their success is due to advances in electronics, which allows unattended operation and interfacing with the commercial power grid. Electronic power switching technology eliminates the need for the generator to be syn ....etc

A technique for on-line detection of incipient faults in the windings of turbine - generator rotors has been developed based on the twin signal sensing method. To detect the developing shorts in any winding, two identical pulses are applied to both ends f the winding and are reflected back .Any abnormality in the winding results in the applied signals being reflected through nonsymmetrical circuits. The difference between the reflected signals are amplified and used as signature signal for further processing. This paper describes the developmen ....etc

PLC BASED PROTECTION AND INTERLOCKS SYNOPSIS

A programmable logic controller (PLC) is an industrially hardened computer based
unit that performs discrete or con tenuous control function in a variety of processing
plant and factory environment. PLC consists of CPU, input device, output device and
Programming device. PLC replaces relays, timers, counters and sequencers.
Our project concerns with PLC based protection and interlocks for
1. Boiler feed pumps.
2. Mill and feeder interlo ....etc
