Abstract

The invention discloses a wide-area synchronous measurement method for factory boundary noise of a transformer station and a noise monitoring device. In the measurement method, a noise measuring process is decoupled into multiple sub measurement steps, time synchronization is ensured by means of wide area time service, and wide-area synchronous measurement is ensured by configuring the same measurement time parameters. The provided device is wireless, passive, light, and conveniently, and can be widely applied to different of noise monitoring environments, a wide-area noise measurement system is formed by combination and disposition, the noise is measured automatically and continuously, the noise monitoring period is in an unmanned on duty way, data is transmitted automatically, there is not secondary input, the reliability of the noise measurement data is ensured, the problems that factory-boundary multi-position noise measurement is asynchronous and data is not reliable of the transformer station are overcome, and the environment evaluation efficiency of the factory boundary noise of the transformer station can be improved greatly. The method can be further extended to other systems which need synchronous measurement, and more intelligent wide-area synchronous measurement is realized.

Description

technical field [0001] The invention relates to the field of noise detection, in particular to a wide-area synchronous measurement method and noise monitoring equipment for substation boundary noise. Background technique [0002] The substation belongs to the substation link of the power grid and plays an important role in the power system. The noise generated by various electrical equipment in the substation will inevitably have an impact on the staff in the substation, nearby residents and the environment. During this period, the high load rate of substations will generate a lot of noise, and the environmental impact of substation noise has received more and more attention. Since 2015, State Grid has organized the formulation of science and technology, smart grid and environmental protection work plans every year, requiring provincial companies to strengthen the supervision of environmental protection technology in the whole process, such as: carrying out noise monitoring ...
