Description
技术领域technical field
本发明涉及一种输变电外绝缘设备污区等级划分技术，特别涉及一种以积污速率划分污区等级的方法。The invention relates to a technology for classifying polluted areas of external insulation equipment for power transmission and transformation, in particular to a method for classifying polluted areas by the rate of pollution accumulating.
背景技术Background technique
污闪事故具有影响面积大、停电时间长、一处跳闸常使临近输变电设备受波及动作、造成的经济损失大等特点，是电力外绝缘设备正常运作、电网安全运行的一大威胁。国内外研究表明，依据外绝缘的积污严重程度配置适当的绝缘水平，能有效防止污闪事故发生。因此，外绝缘污区等级的合理划分对电网防污闪工作尤为重要，可为新建线路设计外绝缘水平、已有线路进行有计划调爬、运行部门实施针对性防污闪措施等提供科学依据。Pollution flashover accidents have the characteristics of large area of influence, long power outage time, one trip often affects nearby power transmission and transformation equipment, and cause large economic losses. It is a major threat to the normal operation of power external insulation equipment and the safe operation of the power grid. Researches at home and abroad have shown that the appropriate insulation level can be configured according to the pollution severity of the external insulation, which can effectively prevent pollution flashover accidents. Therefore, the reasonable division of the levels of external insulation pollution areas is particularly important for the anti-pollution flashover work of the power grid, which can provide scientific basis for the design of external insulation levels for new lines, the planned adjustment of existing lines, and the implementation of targeted anti-pollution flashover measures by operating departments. .
目前，我国主要依据《高压架空线路和发、变电所环境污区分级及外绝缘选择标准》划分污区等级。该标准按照污秽性质、污源距离、气象情况与等值附盐密度，将架空线路和变电所、发电厂划分为不同的污秽等级。后有研究提出以饱和盐密取代年度等值盐密，以期保证线路长期不清扫而无污闪。At present, my country mainly divides the pollution area level according to the "High Voltage Overhead Lines and Power Generation and Substation Environmental Pollution Area Classification and External Insulation Selection Standard". The standard divides overhead lines, substations, and power plants into different pollution levels according to the nature of pollution, distance from pollution sources, meteorological conditions, and equivalent salt density. Later studies proposed to replace the annual equivalent salt density with saturated salt density, in order to ensure that the line will not be cleaned for a long time without pollution flashover.
然而当前我国经济正高速发展，以煤炭为主的能源结构、污染工业的大规模迁移、公路四处延伸带来的汽车尾气污染、以及全球气候异常导致的极端天气多发，都使得电力外绝缘设备积污量出现大幅度的动态变化，污染范围不断改变，污区等级也呈现动态变化特性。因此传统划分污区等级的方法停留在静态描述积污严重程度阶段，每次测量调整所需时间长、人力物力花费大，常滞后于地区积污特性的动态变化，导致难以准确表征各地区当前的外绝缘积污程度，并且不能实现外绝缘设备未来积污量的预测。However, at present, my country's economy is developing at a high speed. The energy structure dominated by coal, the large-scale migration of polluting industries, the automobile exhaust pollution caused by the extension of highways, and the frequent occurrence of extreme weather caused by global climate anomalies all make the power external insulation equipment redundant. The amount of pollution has a large dynamic change, the scope of the pollution is constantly changing, and the level of the pollution area is also dynamically changing. Therefore, the traditional method of classifying pollution areas stays at the stage of statically describing the severity of pollution accumulation. Each measurement adjustment takes a long time, costs a lot of manpower and material resources, and often lags behind the dynamic changes of regional pollution characteristics, making it difficult to accurately characterize the current situation in each area. The pollution level of the external insulation, and the prediction of the future pollution volume of the external insulation equipment cannot be realized.
