This paper describes a technique on conductor bundle geometry optimization by the use of personal computer. To reduce the corona noise, in this paper, a new method for finding the optimal arrangement of subconductors with the minimum surface gradient is proposed. The charge simulation method is used to calculate the electric field of conductor surface and the nonlinear successive quadratic programming is applied to find the optimal arrangement of subconductors. Through some analytical comparisons and corona cage tests, it is proved that a new asymmetric conductor bundle proposed in this paper can more reduce the average surface gradient of the phase conductor and the corona noise than the asymmetric conductor bundle proposed by GE as well as the conventional symmetric ones.
