Abstract
One of the main reasons of generation of intensive noise and vibration in low frequency range are gas pressure pulsations (oscillations) in gas guide systems of power plants. Active noise and vibration control now is considered as efficient method of low frequency noise and vibration for different applications, including reduction of low frequency noise and vibration in gas guide systems of power plants. Results of analysis of application of active noise and vibration control systems for the reduction of power plants low frequency noise and vibration are described. The examples are showing high possibilities and efficiency of active noise and vibration control method. In a meantime, existing constructions of ANVC systems are having some drawbacks. Author’s experience of development of constructions and technical solutions of ANVC systems for reduction of low frequency noise and vibration in power plants gas guide systems is presented. Further perspectives of increasing of efficiency of ANVC control of low frequency noise and vibration reduction generated by power plants are discussed.
