Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0026] The present invention provides a reactor noise selection that can effectively control the field noise of the substation through the reactor noise selection in the substation design stage or the reactor procurement stage, and can be programmed and standardized to control the field noise level of the outdoor substation. method.

[0027] Take the reactor noise selection in a 110kV substation as an example. The reactor layout diagram of the substation is attached image 3 shown (down is north). The reactors are arranged in the north-south direction, and the width between the nor...

Abstract

The invention relates to a reactor noise selection method for controlling the field noise level of an outdoor substation, comprising the following steps: A) initializing the reactor type, at least one reactor is set in the substation; Determine the field boundary noise control point; C) calculate the noise level L at the field boundary noise control point when all reactors work together T ; D) Judgment L T Does it satisfy L T <L S , L S is the noise limit of the substation boundary, if yes, the reactor noise selection is completed, if not, change the reactor type, and return to step B). Compared with the prior art, the present invention has the advantages of standardization, programming, strong operability, high accuracy and strong applicability.

Description

technical field [0001] The invention relates to the fields of field noise control of substations and noise control of power transmission and distribution equipment, in particular to a reactor noise selection method for controlling the field noise level of outdoor substations. Background technique [0002] Boundary noise of substations is one of the common causes of public complaints, and it is also one of the important environmental indicators that need to be controlled during the construction and operation of substations. A lot of work has been done on noise control in previous research on environmental protection of substations. Various technical measures to control noise levels have also been adopted in existing substations, but most of them focus on the noise reduction effect of a single measure. It is worth noting that in the current design practice of substations, most of the noise control design is still in the rough design stage relying on equipment selection and exp...
