摘要
本文对蒙特卡罗法在输电线路防雷性能评估中的应用进行了评价。应用Monte - Carlo方法与ATP软件的接口ATP- de - mc,计算了典型138-kV输电线路在不同塔基接地阻抗ZP下的临界电流和反闪络概率。通过对不同弹数的结果分析,提出了一种同时考虑概率分布误差和离散系数误差的停止判据。结果表明,在高临界电流条件下,输电线路雷电性能的评估需要更多的蒙特卡罗算法,从而需要更多的计算量和模拟时间。停止准则的使用使ZP为10 Ω时的轮数减少21%,ZP为40 Ω和80 Ω时的轮数减少92%,保持了一致和可行的结果,确保了它在蒙特卡罗方法执行中的使用。
On the Assessment of a New Stopping Criterion for the Monte Carlo Method Applied to the Analysis of the Lightning Performance of Transmission Lines
This paper evaluates the use of the Monte Carlo method for the assessment of the lightning performance of transmission lines. By the application of the ATP-DE-MC, an interface between the Monte Carlo method and the software ATP, the critical current and the backflashover probability for a typical 138-kV transmission line under different tower-footing grounding impedance ZP are calculated. From the analysis of the results for different number of Monte Carlo rounds, a stopping criterion is proposed based on the simultaneous consideration of the error of the probability distribution and the dispersion coefficient. It was shown that evaluations of the lightning performance of transmission lines related to high critical current demand more Monte Carlo rounds and consequently more computational efforts and simulation time. The use of the stopping criterion provides decreases of 21% in the number of rounds for ZP of 10 Ω and 92% for ZP of 40 Ω and 80 Ω, maintaining consistent and feasible results that ensure its use in the Monte Carlo method execution.
