ABSTRACT
The entire modern turbo-alternator is two poles machine and driven by steam turbine. Since the efficiency of steam turbine is high at large speeds, the turbo-alternators are designed for speed up to 3000 rpm. Modern turbo-alternators have typical ratings of 60 MW, 120 MW, and 250 MW, 500MW, 1000 MW. In this project we are studying the protection of Turbo-alternator of rating 500 MW in KTPS.
The turbo-alternator protection can be provided with two types of relays, one is comprehensive multi function relay having encapsulated in one single module. The later has a number of protection functions within the relay case does have a number of advantages as compared with single functions generator protection relays. The relay is more compact and requires less external connections. Using numerical techniques, enhanced features such as measurement functions, event and disturbances recording, alternative setting group can also provide remote communications, printing and testing facilities. These features can simplify the task of commissioning, maintenance, and trouble-shooting and post-faults analysis.
In addition, a self monitoring feature, together with communications, allows the monitoring of the relay and the generator on demand, will improve availability of the protection system.
