Pressure pulsation analysis of 5+5 long and short blade pumped storage unit

The vibration of the unit and the building of the pumped storage power station is the key factor affecting the safe and stable operation of the power station, and the hydraulic factor is one of the important sources of the vibration. In this paper, the field tests of 5+5 long and short blade pumping units are carried out, and the amplitude and frequency characteristics of the internal pressure pulsation of 5+5 long and short blade units are emphatically introduced and analyzed.
