抛物线式档端角度观测法测控架空电力线弧垂的误差分析

Error Analysis for Measurement and Control of Overhead Power Line Sag by Span End Angle Observation Based on Parabola Theory

抛物线式角度观测法在架空电力线弧垂测控中被广泛使用,但由于计算模型及测量方法等原因会引起误差,在线路施工与验收时,需要予以充分考虑。

Angle observation method based on parabola theory is widely used in the measurement and control of overhead power line sag.However,the various errors must be fully taken into account in the line construction,inspection and acceptance as these might occur due to the calculation model,measurement method etc.
