The COMPACS® stationary systems were implemented at the Reftinskaya GRES in 2011-2012. On 10 power-units the COMPACS® system provides automatic real-time condition monitoring of 20 smoke-exhauster, 78 hot-blast fans, 20 blow-fans and 8 booster pumps. The systems are connected to 488 vibration sensors, one per bearing assembly, and 130 current sensors.
The implementation of the COMPACS® systems at the auxiliary equipment of the Reftinskaya GRES has allowed to detect malfunctions in time and issue prescriptions for the personnel about the unit’s problems beforehand. During the operation the systems showed high rates of reliability in condition diagnostics. Due to the integration of the COMPACS® system into the data and technological network the personnel can supervise the equipment’s condition in real time from their workplaces in real time. The system makes sudden failures of a unit observable and gradual.
The systems have convenient and clear interface which allows the personnel easily supervise changes in equipment’s condition. In the foreseeable future it is planned to install extra vibration sensors for the vibration level control in three directions, in accordance with operational rules, and a rotation frequency sensor.
To enlarge the abilities of the COMPACS® expert system it is necessary to form the report on the factors which influenced the expert messages.
In the ANALYSIS mode it is necessary to show a grid of the bearing defects on the signal spectrum, as well as of reverse, network and other harmonics.
Since the COMPACS® system is able to receive and process current signals, its next step in development can be the diagnostics of electric motors by the current spectrum.
