摘要
通过边界元法,研究了不同因素下单条管线IR降的变化规律,并建立了多因素影响下管道IR降计算方法。结果表明:建立的数学模型计算得到的IR降与实测值最大误差为-6.38%,能够满足工程应用的需求。
The variation rules of IR drop of a single pipeline under different factors was studied through the boundary element method,and the calculation method of IR drop under the influence of multiple factors was established.The results showed that the maximum error between the IR drop calculated by the mathematical model proposed in this paper and the measured value was-6.38%,which could meet the requirements of engineering applications.
