中文摘要:
      针对变电站软母线的下料长度问题,提出一种二分法的数值求解模型. 首先在假设水平应力已知的条件下,由受力分析建立软母线下料长度的非线性耦合解析模型,进而设计变电站软母线下料长度二分法数值计算模型,并利用二分法得到精确的数值解. 仿真与应用结果表明,数值计算模型能够得到非常准确的下料长度,安装后的软导线总弧垂误差均在-2%~+3%以内,具有良好的施工效果.
英文摘要:
      A dichotomy numerical calculation model was proposed to calculate the cutting length for soft-bus conductor in transformer substation. Under the assumption of that the horizontal stress is known,this article establishes a nonlinear coupling analytical model of soft-bus conductor length through stress analysis. Furthermore,it designs a numerical calculation of soft-bus conductor length in transformer substation. Then the numerical calculation obtains accurate numerical solution through dichotomy. It is demonstrated by the result of simulation and application that an accurate soft-bus conductor length can be worked out through the numerical calculation method. Besides,the total sag error of soft wire after installation is between -2% to +3% so that the construction effect will be satisfactory.
