Description

technical field [0001] The invention relates to the technical field of substation noise monitoring, in particular to a real-time monitoring and multidimensional analysis system for substation noise. Background technique [0002] In order to meet the rapid development of my country's economy, more and more urban substations are being built; at the same time, in order to alleviate the environmental pressure caused by complaints and disputes caused by substation noise, there have been more and more domestic control projects for substation noise in recent years. The survey found that there are still some deficiencies in substation noise engineering governance: the primary and secondary relationship between substation noise control objectives is not clear; The distribution of noise will lead to the phenomenon that the project management effect is not good and the project cost is inflated. At present, sound insulation control technology is still the most widely used method in sub...
