Condition monitoring of turbine blades

Blade tip timing system leads to improved operational flexibilityBlade tip timing

The increased demand for operational flexibility causes low pressure turbines to be more often run under sub-optimal conditions. This leaves them more susceptible to blade vibrations, which can ultimately damage the blade. Through blade tip timing, operators can better estimate the risk of vibrations and adjust plant operation accordingly. Laborelec managed to bring this theoretical concept into practice by installing a tip timing system in the steam turbine of the French DK6 Power Plant in Dunkerque .
