Simulation of Sound Field Distribution in Rotary Condenser Room Based on COMSOL.

With the rapid development of DC transmission technology, the problem of excessive noise of substation boundary caused by the noise of converter station rotary condenser room often occurs. There are few studies on the sound source characteristics and sound field distribution of the rotary condenser, and its noise influence cannot be ignored. In this paper, based on comsol, a scaled simulation model of the rotary condenser room is established. The noise distribution inside and outside the room of the rotary condenser room is calculated, and compared with the measured value, the noise distribution inside and outside the converter station is obtained. The research conclusion can guide the project planning to predict the noise distribution more accurately and avoid the problem of excessive noise after completion
