摘要
随着电力负荷的不断增加,在多种因素的影响下,能够准确有效的计算出电力电缆的载流量,保证电力电缆的安全、有效运行具有重要意义。本文首先介绍电力电缆载流量计算的前景方向,分析其解析计算的理论知识并实际计算种可能发生的问题;其次介绍数值计算中主要包括有限差方法、边界元法和有限元法三种计算方法在计算中的应用,并对其算法特点进行综述。最后,依据现存的研究计算方法,针对具体的实际问题,进行具体实施方法。
As the electrical load increasing, under the influence of various factors, can accurate and effective to calculate the carrying capacity of power cable, ensure the safe and effective running of the power cable is of great significance. This paper introduces the power cable the future direction of load flow calculation, analyzes the analytic calculation of theoretical knowledge and practical calculation of possible problems; Secondly introduces mainly includes the finite difference method in the numerical calculation, the boundary element method and finite element method the application of three kinds of calculation methods in calculating, and its algorithm were summarized. Finally, on the basis of the existing calculation method of the research, in view of the specific practical problems, for concrete implementation method.
