测量埋地长输管线断电电位时,参与同步通断的阴极保护站数量的不同将直接影响到断电电位测量结果.运用边界元数值模拟软件BEASY CP对测量断电电位常用的瞬间断电法开展研究,针对同步通断相邻4个和2个阴极保护站的两种测量方法分别进行模拟计算,对比讨论模拟结果,得出应至少同步通断相邻4个阴极保护站的结论并由此给出关于测量方法方面的建议.

The number of adjacent cathodic protection stations participated in synchronous ON-OFF process directly affects the measurement results when measuring the OFF potential of long-distance underground pipes. Based on the Boundary Element Method(BEM) numerical simulation software BEASY CP, the instant power-off method was researched and 2 kinds of synchronous switching methods were simulated. According to simulation results, the conclusion that the adjacent stations participated in synchronous ON-OFF process should be at least 4 is put forward, and some proposals of measurement method are presented.
