Calculation and Analysis Technology of Ultra High Voltage Engineering Quantity Based on Particle Swarm Optimization Algorithm

This article focuses on the calculation and analysis technology of ultra high voltage engineering quantities, and innovatively introduces particle swarm optimization algorithm to address its complexity and limitations of traditional methods. By constructing a three-dimensional model and using ANSYS software, optimization calculations were carried out based on particle swarm optimization algorithm for the voltage equalization ring of ultra high voltage composite insulators and the end corner ring of transformer windings. The results showed that, under the constraint conditions, the optimized AC (alternating current) line near the converter station injected approximately 2101.1 Mvar of reactive power into the converter station, which significantly improved the reactive power support of the system. After optimization, the steady-state voltage of the converter bus remained at 0.9513 p.u. This method significantly improves the uniformity of the electric field distribution along the surface of the insulator, reduces the maximum field strength, and effectively enhances the insulation reliability of the transformer winding end. This study not only verifies the efficiency and accuracy of particle swarm optimization algorithm in the optimization of ultra high voltage engineering quantities, but also provides new ideas and methods for the future development of ultra high voltage technology.
