Abstract

The invention provides a transformer substation environment noise real-time monitoring and optimization control method, which comprises the following steps of collecting transformer substation noise related basic data, establishing a transformer substation environment noise calculation model based on a sound attenuation basic theory, and designing a noise real-time monitoring point position; noise distribution in the transformer substation is calculated through the sound power level data obtained through measurement and calculation, noise distribution calculation comprises transformer substation emission noise calculation and background noise calculation, and a noise distribution calculation result in the transformer substation is corrected; and performing transformer substation noise monitoring analysis according to the calculated transformer substation noise distribution. All-weather continuous monitoring of the transformer substation is realized, the change rule of the noise of the transformer substation under the conditions of morning, noon and evening, spring, summer, autumn and winter, load change and the like can be comprehensively mastered, and the influence of emission noise and background interference noise and the condition of reaching the standard day and night can be more reliably and easily identified by adopting a real-time monitoring mode; the device has a great effect in environmental protection dispute disposal and publicity and display, and is of great significance.

Description

technical field [0001] The invention relates to the technical field of substation environmental noise monitoring, in particular to a method for real-time monitoring and optimal control of substation environmental noise. Background technique [0002] Substation noise monitoring and analysis is the most important part of State Grid's environmental protection work, and it is an important means to ensure that substation noise environmental protection meets environmental protection standards and to deal with environmental complaints and disputes. At present, the noise monitoring of operating substations mainly relies on traditional manual testing methods, and a small amount of on-line monitoring technology is used. The artificial monitoring method has the following problems in substation noise monitoring: (1) Noise monitoring is greatly affected by environmental background noise (such as insects, birds and traffic, etc.), so it is difficult to ensure that the test results can obj...
