    摘 要:特高壓換流站內(nèi)設(shè)備需要嚴格控制電極表面電場強度,以防止電暈放電現(xiàn)象。±800 kV 換流站用可控消能裝置子單元較多,且處于不同電壓等級,為準確了解各電極表面電場強度的分布情況,考慮計算及外絕緣試驗的可行性,對可控消能裝置建立了簡化的三維模型,采用有限元分析中的直流傳導(dǎo)場進行計算。通過初步仿真結(jié)果與試驗結(jié)果對比分析,對模型中局放較高的部位進行結(jié)構(gòu)優(yōu)化。優(yōu)化后的計算及試驗結(jié)果表明了優(yōu)化措施的合理性及直流場計算的準確性。

    Abstract: The equipment in the UHV converter station needs to strictly control the electric field strength on the electrode surface to prevent the corona discharge phenomenon.There are many controllable energy dissipation device sub-units used in ±800 kV converter stations,and they belong to different voltage levels.This paper established a simplified three-dimensional model of the controllable energy absorption device. It used the DC conduction field in the finite element analysis for calculation. To accurately understand the distribution of the electric field intensity on the surface of each electrode, the feasibility of calculation and external insulation test has been considered.Compared the preliminary simulation results with the test results, it optimized the structure of the parts with high partial discharge in the model. The optimized calculation and test results show the rationality of the optimization measures and the accuracy of the DC field calculation.
    Key words: converter station; controllable energy absorption device; electric field distribution; simulation calcuation; structure optimization;experimental verification
