Application 1. SteamTurbines of different powers.

In this application, the system covers four machines: two by 50 MW, one 65 MW and one 30 MW.  Different set of measurements is performed on each machine, the most extensive one including the following typical measurement paths:

• 5 absolute vibration channels to register vibration velocity
• 10 relative vibration channels to monitor 5 bearings in 2 axes
• 1 channel for axial vibration
• eccentricity
• axial position
• 2 channels of thermal expansion for machine casing
• 2 channels for rotor relative expansion
• 7 channels for measurement of valve position
• 14 channels for temperature measurement of bearings(radial and thrust)
• phase marker
• rotating speed channel

plus non-Technicad related measurements, but integrated with the monitoring system through Data Acquisition Unit:

• active power
• reactive power
• steam temperature
• steam pressure

Due to the number of measurement channels, the JAD16/32 Data Acquisition Units are used. On three of the machines the power unit control systems are employed to visually represent signals received from the TNC2000. The fourth machine is additionally equipped with operator station with  SMMoperator software. Data from all four machines is output to two computer working stations incorporating SMMturbo application software for use by diagnostic engineers.
