直流离子流场的求解问题

Solving Problems of HVDC Current Field

直流超高压线路的电晕损耗以及电力环保中的电除尘器内的电场,其分析计算均可归结为直流离子流场方程的求解问题。本文应用偏微分方程理论中的柯西方法,较严密地论证了它的解答的唯一性,并进一步探讨几种数值分析求解的途径,简要地对此作一判析,同时对边界条件的选取提出看法,这将对深入研究离子流场方程的求解,具有一定的理论意义和实用参考价值。

Calculation and analysis of the corona losses in ultra-high voltage d.c. transmission line and the electric field in electrostatic precipitators for electric power plants can be attributed to the solving problems of d.c. ionic current field. This paper applying the Cauchy Method in the theorem of partial differential equation demonstrates the unique- ness of their solution strictly. It also searches the clue of their numerical analysis and the criteria briefly. In the same time, it suggests the appropriate choice of the boundary conditions. It will be useful in the further study of the ionic current field problems.
