Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of noise occupational exposure level, in particular to a substation noise occupational exposure level online monitoring method and system. BACKGROUND

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute the prior art.

[0003] The substation is an electric power facility that transforms voltage, receives and distributes electric energy, controls the flow direction of electric power and adjusts voltage in the electric power system, and through the transformer, the power grids of various voltage levels are connected. Electric energy enters the substation through the transmission line, enters the transformer through the distribution device, the transformer performs voltage transformation, and then is output through other voltage level distribution devices.

[0004] According to literature, the transformer, high-voltage reactor and the like of the substation are the main sources of noise hazards, and relatively large intensity noise is generated, and at the same time, the overhead line in the station also generates low intensity electromagnetic noise. At present, the operation and maintenance unit of the substation mainly entrusts the third-party technical service organization to implement artificial periodic detection, and the frequency is generally one detection per three years, and each detection time is about one to two days. Under this condition, the timeliness, continuity, dynamics and adequacy of the occupational hazard exposure level data obtained from the substation do not meet the requirements.

[0005] The occupational hazard exposure level is a term in the technical field of occupational health, which generally refers to the exposure level of workers within 8h of a working day or 40h of a working week. In terms of the workplace of the substation, the operation and maintenance post of the substation is the main noise exposure post, and generally the 40h time weighted exposure level of the post needs to be calculated. In other words, the noise occupational exposure level of the substation is the 40h time weighted average value of the total energy of different intensity noises exposed by the operation and maintenance post workers at different inspection points, expressed in equivalent continuous A sound level (dB(A)). It is particularly pointed out that the noise occupational exposure level is essentially different from the simple device noise monitoring value.

[0006] The different inspection points of the operation and maintenance post of the substation have different noise intensities, and the calculation of the noise occupational exposure level of the substation should realize the 40h time weighting of the total energy of different noise intensities. However, since the actual work in the field has hundreds of inspection points, if all the points are monitored online, it is obviously unrealistic; even if all the points are monitored online, the pre-monitoring control requirements and the subsequent occupational hazard exposure level calculation are also difficult.

[0046] Figure 2 Figure 11 is a flow chart of the substation noise occupational exposure level online monitoring method provided for the embodiment 1 of the present application. DETAILED DESCRIPTION

[0047] The present application will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0049] It should be noted that the terms used herein are only intended to describe specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and it should also be understood that the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0050] The embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0051] Embodiment 1

[0052] In order to better illustrate the problems raised in the background art, this embodiment takes 10 500kV substation noise actual detection data as an example to summarize the substation noise characteristic distribution, as shown in Figure 10. Figure 1 As shown in Figure 10, among the 10 500kV substation noise actual detection data, 3 values are greater than 80dB(A), all from the main transformer, due to the noise influence generated by the main transformer, the noise detection values of the main transformer and outgoing line, and the main transformer arrester are in the range of 70-80dB(A); the noise values of the high-voltage reactor are mainly generated by itself, and the detection results show that the noise values are between 66-80dB(A); the values below 70dB(A) are mainly distributed in overhead lines, switches, disconnectors, busbars, etc., most of which are in the range of 50-60dB(A), and some of which exceed 60dB(A) but do not exceed 63dB(A); the noise values of the main transformer span three dimensions of 60-70, 70-80 and 80-85dB(A), and the noise values of the overhead lines are generally lower than 55dB(A).

[0053] The above data explains the basic characteristics of different inspection points of the substation operation and maintenance post contacting different noise intensities, and the calculation of the noise occupational exposure level of the substation should realize the energy summation of different noise intensities for 40h time weighting. Since there are hundreds of inspection points in the actual work, it is obviously unrealistic to realize online monitoring of all points. Even if all points realize online monitoring, the monitoring control requirements in the early stage and the calculation of the subsequent occupational hazard exposure level are also difficult.

[0054] Therefore, the embodiment provides a substation noise occupational exposure level online monitoring method, which realizes the control of the minimum and optimal noise monitoring points, and the most reasonable and scientific data acquisition and presentation. As shown in Figure 2 , specifically comprising:

[0055] controlling the noise monitoring points according to the transformer level;

[0059] In the embodiment, the control method of the noise monitoring points comprises:

[0060] (1) 1 point at the transformer body incoming line side;

[0061] (2) 1 point at the transformer body outgoing line side;

[0062] (3) 1 point on each side of the transformer body;

[0063] (4) 1 point at the transformer arrester;

[0064] (5) 1 point at the transformer voltage transformer;

[0065] (6) 1 point at the transformer neutral point reactor;

[0066] (7) 1 point at the transformer neutral point voltage transformer;

[0067] (8) 1 point at the high-voltage reactor body incoming line side;

[0068] (9) 1 point at the high-voltage reactor body outgoing line side;

[0069] (10) 1 point on each side of the high-voltage reactor body;

[0070] (11) 1 point at the high-voltage arrester;

[0071] (12) High resistance neutral point voltage transformer 1 point;

[0072] (13) High resistance neutral point reactor 1 point;

[0073] (14) High resistance neutral point voltage transformer 1 point;

[0074] (15) High resistance neutral point arrester 1 point.

[0075] Thus, the noise monitoring point control method according to the transformer level includes:

[0076] If the transformer level is 110kV transformer, the selected noise monitoring points are (1)-(3);

[0077] If the transformer level is 220kV transformer or 330kV transformer, the selected noise monitoring points are (1)-(5);

[0078] If the transformer level is 500kV and above transformer, the selected noise monitoring points are (1)-(15).

[0079] As an optional implementation, if there are multiple power substation equipment (such as multiple high resistance neutral point reactors), only one of them is selected for control.

[0080] In this embodiment, the monitoring terminal is arranged on the power substation equipment or its auxiliary facility body, and an equivalent continuous A sound level value is recorded every 1 minute, and after continuous monitoring, it is output according to the rule of year-month-day-hour-minute-measurement point number-LAeq; wherein the equivalent continuous A sound level value is represented by LAeq, the unit is dB(A), and the number is unique, such as ①-LAeq for the transformer body inlet side, and thus the acquisition of noise monitoring data is completed.

[0081] As an optional implementation, the monitoring terminal is fixedly installed on the power substation equipment or its auxiliary facility body, 1.5m away from the inspection ground, and the microphone is kept at a distance of not less than 30cm from the body.

[0082] Among them, the sound level meter or dosimeter is arranged close to the sound source of the cooling fan, oil pump and other sound sources; the sound level meter or dosimeter is additionally provided with a wind / rainproof cover when arranged outdoors.

[0094] (4) The arithmetic mean of the occupational noise exposure levels of each maintenance worker is taken as the occupational noise exposure level L of the substation:

[0095]

[0096] In the embodiment, the noise source values of all noise monitoring points are determined according to the equivalent continuous A sound level values, and the process of determining the substation noise occupational exposure level according to the noise source values of all noise monitoring points includes:

[0097] (1) Without numbering the substation operation and maintenance personnel, first calculate the noise source values Y of all noise monitoring points:
