Abstract

The invention provides a transformer substation noise monitoring method, and belongs to the technical field of noise monitoring. The method comprises the following steps: S1, collecting noises: generating a continuous noise curve a; and generating a continuous noise curve b; S2, calculating a noise difference value: establishing a coordinate system A, and sequentially calculating to acquire the noise difference value fn according to each noise node; S3, drawing a noise curve: establishing a coordinate system B, and drawing a noise curve c; S4, constructing a noise area: setting a noise deviation value-An-+ Bn, correspondingly generating a curve c1 and a curve c2, and forming a noise area D between the curve c1 and the curve c2; and S5, carrying out real-time measurement and comparison, inputting the coordinate system B into the noise monitoring system, comparing real-time acquired noise signals, and screening equipment, a switching mechanism or a driving mechanism corresponding to the part outside the noise area D for detection or maintenance. According to the transformer substation noise monitoring method, the transformer substation noise can be monitored in real time, and the operation condition of the transformer substation can be comprehensively reflected.

Description

technical field [0001] The invention belongs to the technical field of noise monitoring, and more specifically relates to a noise monitoring method of a substation. Background technique [0002] The main noise source of the substation is generated by various components on the working path. The noise monitoring in the substation can preliminarily grasp the operation status of the equipment. When the equipment fails, the corresponding noise will also change. Monitoring the noise of the substation can help understand the equipment Operational status, timely detection of abnormalities in equipment operation. [0003] At present, the inspection method is mainly used to collect the noise of the main equipment. This monitoring method will be affected by the environmental noise, and it cannot fully reflect the operation status of the substation, and there are certain blind spots. Contents of the invention [0004] The purpose of the present invention is to provide a substation no...
