Description
技术领域technical field
本发明涉及一种噪声排放数据处理方法，尤其是涉及一种用于变电站站界噪声排放数据处理方法。The invention relates to a noise emission data processing method, in particular to a noise emission data processing method for substation boundaries.
背景技术Background technique
随时我国经济快速发展，用电负荷急剧增大，变电站建设正在逐步向城市中心发展。变电站周围不再仅仅是空地、马路、厂房，还包括写字楼，商业区，甚至居民区。变电站在运行过程中的噪声排放治理是国家电网公司“十一五”和“十二五”科技规划的重点任务之一。目前《工业企业厂界环境噪声排放标准》G812348-2008仅规范变电站站界噪声排放标准，标准要求：噪声排放测量值与背景噪声值相差应大于3dB(A)。结果评价：各个测点的测量结果单独评价。With the rapid development of my country's economy at any time, the electricity load has increased sharply, and the construction of substations is gradually developing to the center of the city. The surroundings of substations are no longer just open spaces, roads, and factory buildings, but also office buildings, commercial areas, and even residential areas. Noise emission control of substations during operation is one of the key tasks of State Grid Corporation's "Eleventh Five-Year" and "Twelfth Five-Year" scientific and technological planning. At present, G812348-2008 "Environmental Noise Emission Standards at the Boundary of Industrial Enterprises" only regulates the noise emission standards at the substation boundary. The standard requires that the difference between the measured noise emission value and the background noise value should be greater than 3dB(A). Result evaluation: The measurement results of each measuring point are evaluated individually.
电是连续生产不能储存的产品，因此变电站设备不能随时停运，且大部分变电站噪声排放测量值与背景噪声值差值一般小于3dB(A)，无法满足标准的检测要求；且站界噪声测点多，如以表格形式罗列出各测点噪声数据，无论对于专业人士或是非专业人士，都显得很不直观，因此运用《工业企业厂界环境噪声排放标准》GB12348-2008开展变电站站界噪声排放评估需要建立一种专用的检查数据处理方法，才能更好的为治理变电站的噪声排放提供数据支撑。Electricity is a product that cannot be stored due to continuous production, so the substation equipment cannot be shut down at any time, and the difference between the noise emission measurement value of most substations and the background noise value is generally less than 3dB(A), which cannot meet the standard detection requirements; and the noise measurement of the station boundary If there are many points, if the noise data of each measuring point is listed in the form of a table, it is not intuitive for professionals or non-professionals. Noise emission assessment needs to establish a special inspection data processing method in order to better provide data support for the control of noise emissions in substations.
本发明是以频谱特征分析法确认变电站噪声排放，以图示法显示变电站站界噪声排放水平。The invention confirms the noise discharge of the transformer substation with a frequency spectrum characteristic analysis method, and displays the noise discharge level of the substation boundary with a graphic method.

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.
实施例：Example:
如图1所示，一种用于户外变电站站界噪声排放数据处理方法，该方法用于户外变电站噪声排放的评估中。首先要对某一变电站进行现场勘查，获得变电站平面布置图，同时要对变电站周围环境进行摸底，绘制变电站站界与其周围建筑物的相对位置分布图。然后检测变电站内设备主要噪声源的频谱特征。在对变电站站界噪声进行测试后，分析站界噪声频谱特征与站内设备主要噪声源频谱特征的相似程度，确定检测站界噪声的声源，对相似程度高的检测站界噪声结果以“红色”或“绿色”字体标注于上述分布图中；对相似程度低的检测站界噪声结果以“灰色”标注于上述分布图中；并将变电站站界对环境造成影响的程度不同以不同颜色进行标识，以获得变电站站界噪声排放的评估结论，为噪声治理提供技术支持，噪声数据处理规范包括以下内容：As shown in Figure 1, a data processing method for noise emission at the boundary of an outdoor substation is used in the evaluation of noise emission of an outdoor substation. First of all, it is necessary to carry out on-site survey of a certain substation to obtain the layout of the substation. At the same time, it is necessary to conduct a thorough investigation of the surrounding environment of the substation and draw a distribution map of the relative position of the substation boundary and the surrounding buildings. Then the spectrum characteristics of the main noise sources of the equipment in the substation are detected. After testing the noise at the substation boundary, analyze the similarity between the frequency spectrum characteristics of the noise at the boundary of the station and the spectrum characteristics of the main noise sources of the equipment in the station, determine the sound source of the noise at the detection station boundary, and mark the results of the noise at the boundary of the detection station with a high degree of similarity as "red". " or "green" fonts are marked in the above distribution map; the noise results of the detection station boundaries with low similarity are marked in "grey" in the above distribution map; To obtain the assessment conclusion of noise emission at the substation boundary and provide technical support for noise control. The noise data processing specification includes the following contents:
(1)红色方框背景黑色字体：显示该区域噪声数值，并且噪声排放超标，需要针对性噪声治理；(1) Black font on the background of the red box: display the noise value of the area, and the noise emission exceeds the standard, and targeted noise control is required;
(2)绿色方框背景黑色字体：显示该区域噪声数值，并且噪声排放合格，无需治理；(2) Black text on the background of the green box: display the noise value of the area, and the noise emission is qualified, and no treatment is required;
(3)灰色方框背景黑色字体：显示该区域噪声数值，并且背景噪声接近排放噪声，无法检测；(3) Black font on gray box background: Displays the noise value in this area, and the background noise is close to the emission noise, which cannot be detected;
(4)红色端线：噪声敏感区，尽快实施噪声治理；(4) Red end line: Noise-sensitive area, implement noise control as soon as possible;
(5)紫色端线：噪声观察区，开展噪声可行性方案研究，需要时在治理；(5) Purple end line: Noise observation area, carry out noise feasibility study, and control when necessary;
(6)绿色端线：合格区，无需治理；(6) Green end line: qualified area, without treatment;
(7)太阳标志：日间检测时间段；(7) Sun sign: daytime detection time period;
(8)月亮标志：夜间检测时间段。(8) Moon sign: detection time period at night.
采用变电站站界噪声排放规范结果显示，该变电站的北面和西面靠近交通主干道的站界噪声排放合格无需治理，南面和东北方向靠近厂房的站界需要开展噪声处理可行性调查，并且制定降噪方案，而东南方向靠近居民区的方向属于噪声敏感区，需要对此区域进行针对性的噪声处理，尽快实施噪声治理方案。The results of adopting the substation boundary noise emission specification show that the noise emission of the substation boundary near the main traffic road in the north and west of the substation is qualified and does not need to be treated, and the station boundary close to the factory building in the south and northeast needs to carry out the feasibility investigation of noise treatment, and formulate a reduction plan. However, the direction near the residential area in the southeast is a noise-sensitive area, and it is necessary to carry out targeted noise treatment in this area and implement the noise control plan as soon as possible.
