摘要:
絕緣子是直流輸電換流閥塔的重要組成部分,針對絕緣子的分析對于換流閥塔的設計具有重要意義。文中考慮支柱絕緣子的換流閥屏蔽系統的表面電場分布,提出了基于積分方程的場域元與邊界元耦合的計算方法。將場域元法與邊界元法耦合,共同模擬考慮支柱絕緣子的換流閥屏蔽系統。通過與二維有限元算法的對比,驗證了算法的正確性。建立不同情況下的換流閥屏蔽系統模型,采用耦合算法對其進行分析,得出了考慮絕緣子前後屏蔽系統的電場分布以及絕緣子內部的電場分布,提高了計算精度,拓展了傳統邊界元算法的應用範圍。
Abstract:
The insulator is an important part of the HVDC converter valve,and the electric field analysis of the converter valve is very important for the design of the HVDC converter valve. In this paper,the surface electric field distribution of the converter valve shield system considering the post insulators. In order to improve the calculation efficiency,the integral equation field domain element and boundary element coupling method is proposed. The integral equation field domain element method is introduced into boundary element method(BEM) to deal with the calculation. The method is proved to be correct through the comparison with 2D finite element method result. The post insulator models in different situation is built,by use of coupling method,the surface electric field intensity of shielding system and the electric field in the insulator are analyzed,and the range of application of boundary element method is broaden.
