| Summary: | A new method applying the biogeography-based optimization (BBO) technique is
presented for the optimization of high voltage electrode surfaces. The aim is
to obtain the optimization of the electrode shape in order to achieve a
uniform field distribution along the surface of the electrode and maintain
maximum field stress at minimum value. The principle of the developed
optimization technique is described with an axi-symmetric single-phase GIS
bus terminal electrode considered as a quarter-ellipse. In this scheme
different aspects of the optimization technique are compared by means of
semi-infinite line charges and ring charges to compute the electric field
with the charge simulation method (CSM). The new Biogeography Based optimized
approach helps in achieving a uniform field distribution with a minimum
electric stress on the electrode surface and a minimum deviation angle for
the otherwise normal stress vector, holding the assignment factor within the
assigned range. The deviation angle is the more sensitive indicator of the
simulation accuracy .The assignment factor has an impact on simulation
accuracy. The combined BBO/CSM algorithm is capable of finding a
better-quality solution, better accuracy, better convergence characteristics
and computational efficiency. |
