The results of experimental studies of joint two-channel active suppression of pressure surges and vibrations of the working medium to reduce vibration transfer through pipeline compensators of power plants with liquid are considered. No data is available in academic periodicals on the use of active methods to solve this problem. The test bench design with excitation and active damping systems of vibrations and pressure surges is given. Efficiency of more than 15 dB from the use of broadband active systems for damping vibration forces transmitted through the compensator and pressure surges of the working medium inside it, both working separately and together in the frequency range from 10 to 275 Hz has been experimentally obtained. In the narrower frequency ranges from 10 to 350 Hz, active damping up to 25 dB has been obtained.
