Experience in developing and introducing an automated monitoring and diagnostic system for a turbine-generator unit at the Onda hydroelectric station

Conclusions  o li]1.|As a result of introducing an automated monitoring and diagnostic system, the operating personnel of the hydrostation are able to do the following: to determine the occurrence of troubles in the main components and systems of the unit at an early stage of their development and thereby to avoid emergency situations; to plan the volume and time of overhauls; to have a graphic and convenient check of the parameters characterizing the condition of the unit; to automatically or on demand record the monitored parameters in daily records, which makes the entries more reliable and vacilitates the work of the personnel. li]2.|The software-algorithm unit of the system determining troubles in the main components of the unit is sufficiently typical and can be easily adapted to particular designs and layouts of the units at various hydrostations. li]3.|The hardware created for modern computers and the modular principle of constructing the system also provide easy applicability of the system to various designs of the units. li]4.|The developed variant of the system of detecting troubles of a unit with manual input of data into the computer can be used for checking the knowledge of the operating personnel and can serve as a graphic supplement to the operating instructions for each particular hydrostation. It can be made also in a training and examination variant. Translated from Gidrotekhnicheskoe Stroitel'stvo, No. 11, pp. 26–28, November, 1999.
