避雷针最佳高度计算的BASIC程序

本文分析电力工程设计人员计算避雷针(线)保护范围的实际情况出发,提出了用微机 BASIC语言求解避雷针(线)最佳高度的设想,计算机模拟人工计算方法选择最佳高度.在此基础上,简要论述了本程序的设计思想:一是程序的功能要全;二是操作要简单方便.本程序还介绍了用计算机如何直接选择避雷针(线)的最佳高度.解决方法是先找出被保护物受保护的条件,然后利用计算机运行速度快的优点,结合编程技巧,让计算机模拟人工计算,选择过程,快速而准确地找到答案.

THE BASIC PROGRAM OF CALCULATING THE OPTIMAL ALTITUDE OF LIGHTNING ROD/LINE

Based on analysing the real difficulty of the electrical engineering designer in calculating the protective scope of lightning rod/line,this article recom- mends an idea of using BASIC program in the microcomputer to calculate the optimal altitude of lightning rod/line,that is,using the analog human calculating method.On the above fundmentals the article briefly expresses the designing idea of the program.The first is the program should be of complete function,and the second is the operation must be easy and conve- nient.The program has also introduced how the computer directly selects the optimal altitude of the lightning rod/line.In short,the solution is finding the condition first,under which the item protected may appropriately be protected,then taking advantage of the quick operation of the computer and the technology of working out the program;next,making the computer simulate the calculating done by hand,select the processes and give the correct answer quickly.
