Condition Monitoring and Automatic Diagnostics of the auxiliary equipment of the typical electric stations

Print

In order to provide stable, uninterruptible process of power production, one needs the constant condition control of the electric stations equipment. However, mainly, the general electric mechanisms - turbines – are equipped with the operational control and blocking systems. At the same time for the ensuring of a turbine operation it is necessary to use a few dozens of auxiliary equipment such as: different grinders, blowing fans, smoke-exhausters, feed, condensate, circulating, net pumps, coolers. Though, many auxiliary units are operated with no reserve and their sudden failure leads to the reduction of the amount of produced energy right up to full shutdown of the turbine.

Sudden failures are determined by the lack of constant automatic condition monitoring and diagnostics of auxiliary equipment. Usually, the vibration-diagnosing staff, which controls the equipment of thermoelectric power station by means of portable instruments, counts 2-3 members, and the number of the power station units is about several hundreds. In connection with that, the interval of the "manual" diagnostics of units exceeds the failure nucleation period, which leads to the sudden (from the operational personnel point of view) failure and faults of main units operation.

Equipping the auxiliary units of the power stations with systems of automatic diagnostics and condition monitoring COMPACS® is a real way to provide safe and reliable operation of electric stations.

The COMPACS® system ensures reliable diagnostics of the bearing defects, lubrication defects, technological process violations (cavitation, hydro-blows, etc.), defects of shaft centering and rotating parts balancing, poor fastening of pumps and electric motors, electro-magnetic defects, face seal failures more than 70% of which are caused by the high vibration rates of pumps and electric motors.
