System introduction was preceded by installation at specially selected hydroelectric power stations having the most difficult working conditions.
Zagorsk hydropower station was chosen with a 200 MW generator, heaving several difficult modes (generating, pump, synchronously-compensatory, as from a generator mode, and a pump mode) with big dynamic loadings and frequent start-ups (design number of start-ups of the generatorengine within a year, not less than 1400, number of transients within a year to 2750).
Other stations for working off low-frequency channels of measurement of vibration are chosen such as the Saratov hydropower station, whose hydro units have the lowest rotation speed in the world (50 rev/min – 0,83 Hz).
