摘要(Abstract):

GIS(气体绝缘金属封闭组合电器)作为超高压变电站内的核心基础设施,其稳定性是变电站安全的重要保证。GNSS(全球导航卫星系统)是目前广泛应用于变形监测的一种新技术。将GNSS技术应用于超高压变电站变形监测,自主研制变形监测解算系统,利用BDS(北斗卫星导航系统)对GIS设备与地基进行连续的变形监测。通过对连续31天的实测数据进行处理,评估变形监测精度。实验结果表明,在复杂的超高压变电站环境下,BDS变形监测精度为北方向2.2 mm,东方向1.4 mm,高程2.3mm,达到毫米级的要求。
GIS(gas insulated metal-enclosed switchgear) is a core component in the EHV substation, and its stability is key to substation safety. GNSS(global satellite navigation system) is a new technology widely used in deformation monitoring at present. In this paper, GNSS technology is applied to deformation monitoring of EHV substation, and a deformation monitoring solution system is developed independently. Continuous deformation monitoring of GIS equipment and foundation is carried out by using BDS(Beidou satellite navigation system). The deformation monitoring accuracy is evaluated by processing the measured data for 31 consecutive days. The experimental results show that the accuracy of BDS deformation monitoring is 2.2 mm in the north, 1.4 mm in the east, and 2.3 mm in the elevation in a complex EHV substation environment.
