Abstract

This paper deals with the measurement of the steam turbine blade vibrations in power systems via the blade tip timing (BTT) method. It describes a BTT principle and the sensor instrumentation for the vibration measurement. The introductory part of the paper is devoted to the description of experiments on Campbell machine. It also shows how obtained signal waveforms from the Campbell machine can simplify the design of the electronic part. The main part of the paper is concerned on the hardware implementation of BTT method in the field programmable gate array (FPGA) as well as the sensor signal conditioning and processing. It also shows signal changes of the sensor output regarding to the different sensor placement. Finally, the results of the digital signal processing using developed electronic hardware is described in the paper.
