摘要
本文提出了一种直流离子流场数值计算的新方法。采用加权余量法来直接求解离子流场电位和空间电荷的方程,不仅可以用于高压直流输电线路离子流场的计算,同时也可用在其它电晕放电的研究中。该法无需采用传统的Deutsch假设,可以考虑风对离子流场的影响。最后给出了离子流场的一些计算结果,并与有关实测结果进行了比较。
This paper described a new method of numerical calculation of DC ion flowfield.The Poisson's equation and the current continuity equation are solvedby using the method of weighted residuals.Both in HVDC transmission linesand in other corona discharge problems,the commonly-used Deutsch's assumption do not need to be adopted in the method.And the effects of wind onspace charge can be considered.Finally,the calculated values of electricfield and ion current density are prssented.The theoretical results are alsocompared with that obtained from test lines.
