高压XLPE电缆绕组超导调相机定子结构设计与模型测试OA

Using XLPE(cross-linked polyethylene)cables as stator windings in a superconducting synchronous con-denser can significantly increase its voltage rating and enable direct grid connection.This novel configuration is re-ferred to as a superconducting synchronous condenser with high-voltage XLPE cable windings(hereinafter"super-conducting synchronous condenser with high-voltage windings").First,a stator structural scheme for the supercon-ducting synchronous condenser with high-voltage windings is proposed,and electromagnetic design of a 15 Mvar/35 kV unit is carried out based on the characteristics of the high-voltage stator structure.Then,electromagnetic per-formance simulations and structural strength calculations are conducted for the proposed condenser,and the feasibil-ity of the high-voltage stator scheme is validated in terms of both electromagnetic rationality and mechanical strength reliability.Finally,a segmented high-voltage stator prototype is developed,key manufacturing processes are summa-rized,and the insulation reliability of the XLPE cable windings is experimentally verified.The results provide theo-retical support for the engineering application of superconducting synchronous condensers with high-voltage wind-ings.
