Recently, research and development of micro gas turbine centered micro co-generation system is conducted actively. To operate such a system, gas compressor is necessary because pressure level in the supply gas pipeline is lower than the required pressure level. It well known that in the gas supply pipeline system pressurized by a reciprocating compressor, pressure pulsation of the supply pipeline is often induced by the resonance of the gas column. In this paper, first we report data observed in the actual system and then propose an idea of countermeasure by utilizing the combination of Roots blower and a small size tank to avoid resonance. We also investigated the effect of anti-resonance device by changing the location of the device through measurement of the pressure level and finally found the optimal location for installing the device.
