【摘要】：近年来,鸟害跳闸故障在四川电网跳闸故障中所占的比例越来越高,已成为破坏电力系统安全稳定运行的主要故障之一。虽然电力部门采取了多项防鸟害措施,但要么防鸟工作不到位,部分重鸟害区域防鸟害装置选择不当造成防鸟效果不佳,要么防鸟过当,导致了许多不必要的经济损失。因此,有必要建立输电线路鸟害等级预警模型,指导电力部门可以针对不同鸟害等级的杆塔进行差异化防鸟治理,提高防鸟装置的利用效率;同时,建立鸟害预警系统监控较高鸟害等级的杆塔当前的鸟害警报级别。本文通过收集四川电网近十年来的鸟害跳闸故障数据,并结合全国各地鸟害易发生区域数据资料进行分析,发现鸟害跳闸故障的发生,与不同的季节、不同的时间段、杆塔周围的地理环境特征以及杆塔自身结构特征有关。本文以杆塔周围的地理特征和杆塔结构特征为研究对象,采用综合评价方法,并结合合适的权重系数确定方法,建立了输电线路鸟害等级预警模型,并提出了以鸟害等级指数为衡量依据的四级鸟害等级划分方法。鸟害预警系统将杆塔鸟害警报设定为4级,以蓝、黄、橙、红4种不同的颜色依次从低到高表示鸟害警报级别;其中,蓝色代表4级警报,红色代表1级警报;系统的工作流程如下:首先,预警系统的数据分析模块接收自鸟害等级较高杆塔处采集到的杆塔周围鸟类风险指数数据,并根据鸟类风险指数的大小评定各杆塔当前的鸟害警报级别;其次,系统的预警模块将各杆塔的鸟害警报级别在图层上以系统设定的颜色体现出来,并对当前为1级和2级鸟害警报级别的杆塔做闪烁处理,以达到对各杆塔预警的目的;最后,以发生闪烁警报的杆塔为圆心,操作人员设定的缓冲半径进行缓冲区分析,警示电力部门加强警戒可能发生鸟害跳闸的区域。
[Abstract]:In recent years, bird damage tripping fault accounts for more and more in Sichuan power grid tripping fault, which has become one of the main faults that destroy the safe and stable operation of power system.Although the electric power department has taken many measures to prevent bird damage, either the bird prevention work is not in place, the improper selection of bird control devices in some heavy bird damage areas results in poor bird control effect, or the bird control is excessive, resulting in many unnecessary economic losses.Therefore, it is necessary to establish an early warning model of bird damage level for transmission lines, which can guide the power department to carry out differentiated bird control for different bird damage levels of pole towers, and improve the utilization efficiency of bird prevention devices, at the same time,A bird hazard warning system is established to monitor the current bird hazard warning level of the tower with a higher bird damage level.By collecting the data of bird damage tripping in Sichuan power grid in the past ten years and analyzing the regional data of bird damage easily occurring in China, it is found that bird damage tripping fault occurs in different seasons and different time periods.The geographical environment around the tower and the structure of the tower are related.In this paper, taking the geographical characteristics and tower structure characteristics around the tower as the research object, using the comprehensive evaluation method and combining with the appropriate weight coefficient determination method, the early warning model of bird damage grade for transmission lines is established.A four-level classification method of bird damage grade was put forward based on bird damage grade index.The bird damage warning system sets the bird damage alarm level of the pole tower to four levels, and uses four different colors, blue, yellow, orange and red, to indicate the bird damage warning level from low to high, among which, blue is for level 4, red for level 1, and red for level 1.The workflow of the system is as follows: first, the data analysis module of the early warning system receives the bird risk index data around the tower collected from the higher bird damage level.And according to the size of bird risk index to evaluate the current bird damage alarm level of each tower. Secondly, the warning module of the system reflects the bird damage alarm level of each tower on the map layer with the color set by the system.In order to achieve the purpose of early warning of each tower, the buffer radius set by the operator is analyzed by using the tower with the tower of the flashing alarm as the center of the tower, and the buffer radius set by the operator is analyzed.Alert the power department to areas where bird tripping may occur.
