A method for low pass filtering data used in change-detect compression of data collected from a system includes buffering the data from said system. Rolling averages of the buffered data are calculated where the calculation of the rolling averages low pass filters the data. Change-detect compression is performed on the rolling averaged data, and the compressed data are archived. The archived data are transmitted to a central location and received. The received data are archived at the central location.
An apparatus for providing active clearance control between blade tips and seals in a turbomachine comprising: a first stator carrier segment, with stator seals centripetally disposed on it; a second stator carrier segment located along a same circumference as the first stator carrier segment, also with stator seals centripetally disposed on it; a shell that adjustably houses the first stator carrier segment and the second carrier segment; at least one displacement apparatus in operable communication with at least one stator carrier segment and configured to position the at least one stator carrier segment to provide active clearance control to the stator seals disposed on the at least one stator carrier segment.
A system and method for tuning a turbine comprises a turbine controller coupled to the turbine, a first computer system coupled to the turbine controller and located locally to the turbine, and a second computer system for exchanging data with the first computer system. The second computer system is located remotely from the turbine and exchanges data with the first computer system via a network connection such as the internet, an intranet or a virtual private network (VPN). Data relating to a characteristic such as turbine combustion dynamics and/or emissions is transmitted by the first computer system to the second computer system. The second computer system transmits control data over the network connection to the first computer to tune the turbine.
A monitoring system for rotating equipment includes detection of temperature conditions in various areas of the system including motor and pump bearings, mechanical seal environment including seal flush, seal cooler and seal reservoir and process fluid temperature. The monitoring system allows for the prediction of component failures and a proactive repair schedule which minimizes if not eliminates component damage.
