基于线性拟合和差值补偿的跳线计算方法研究

Research on Calculation Method of Jumper Based on Linear Fitting and Difference Compensation

以最小二乘法线性拟合和差值补偿法为基础,对1000 kV单回路特高压交流输电线路跳线设计方法进行优化,提出一种新的跳线安装设计方法,简化了跳线安装设计流程,避免了常规“穷举算法”中因输电线路杆塔尺寸、转角度数、绝缘子串长度、绝缘子串倾斜角等边界条件变化产生的“逐塔逐相”反复计算,有效提升跳线设计工作效率和设计质量。

Based on the least square fitting method and difference compensation method,the jumper design method is optimized for 1000 kV UHVAC single-circuit transmission line.A new design method is put forward to simplify the installation and design of jumpers,which can avoid the repeated calculation of transmission line tower size,rotation degree,length and inclination angle of insulator strings etc because of boundary condition changes in the conventional"exhaustive algorithm".The proposed mentod can effectively enhance the design efficiency and design quality for jumpers.
