Data processing of deformation monitoring for Tai’an pumped storage power station

正确有效的变形监测对电站的安全运行至关重要。高精度的变形监测控制网数据处理与常规监测稍有不同,本文结合泰安抽水蓄能电站一等基准网复测数据,进行气象改正、斜距改平、投影改正,对比了气象改正和投影前后的边长变化,采用限差法分析了泰安抽水蓄能电站一等基准网的变形情况,阐述了高精度平面控制网变形监测数据处理的一般方法,总结了影响控制网变形监测结果的一些因素。

Correct and effective deformation monitoring is very important for the operation of power plants.Data processing of high precision deformation monitoring control network is slightly different from conventional monitoring. This paper firstly carries out meteorological correction,oblique distance leveling and projection correction based on the re-measured data of first-order reference network of Tai’an pumped storage power station. Then compares the changes of side length before and after meteorological correction and projection,and the first-order reference network of Tai’an pumped storage power station is analyzed. The general method of data processing for deformation monitoring of high precision plane control network is expounded,and some factors affecting the results of deformation monitoring of control network are summarized.
