Rotating blades state evaluation using relative rotor vibration measurement considering the impact of operating conditions
Original language description
A turbine can be regarded as a heart of most of installed power plants. The process of heat energy into rotational motion conversion is performed there. The key part of this machine is a rotating blade. Its perfect construction is required for a proper operation. That is the reason, why it is necessary to monitor blade condition. Early detection of blade failure formation can avoid unexpected shutdown, which may cause very high economic losses. It is important especially in terms of the last stages of low-pressure turbine part, where are the longest blades which tend to vibrate at most. This paper describes the effects of operating conditions on blade eigenfrequencies. The results from this research are used to precise real blade natural frequency estimation and to prevent possibly incorrect blade state evaluation. Case-study described in this paper is based on long-term data from steam turbine operation monitoring together with data concurrently measured using relative rotor vibration sensors.
