Gas Turbine protection information
Gas Turbine protection information
(OP)
Hallo everybody,
does anybody have or can recommend some document explaining the Gas or STeam turbine protection system, the possible avoided damages ? An example would be : what is the reason for tripping the Turbine, when I have low fuel gas temperature ? Do I get an unstable burning condition and do I have long-term blade-damage ?
Thanks in advance,
Marcus

RE: Gas Turbine protection information
the "rules" during that time for protection defined three levels;
1) could result in the loss of life
2) could result in loss of equipment
3) could result in increase maintenance
for level 1, events like over speed, the protection was redundant and testable
for level 2, events like loss of lube oil, the protection was manditory
for level 3, events like high vibration, the protection was recomended, but optional
maintaining unit availableity was a high (secondary priority). thus the trip protection was to ensure there was a real need to do so and not have conservitive tripping logic
the impression I get from today's controls with the ease of adding a program instruction is trips are becoming "if in doubt, trip it out"

General philosophy for protection is explained by @BYRDJ. You need to check the machine specific O&M manual where such things would be described.
