摘要(Abstract)：

采用XLPE（交联聚乙烯）电缆作为超导调相机的定子绕组可大幅提高其电压等级，实现调相机与电网的直连运行，这种新型调相机被称为高压XLPE电缆绕组超导调相机（简称“高压绕组超导调相机”）。首先，给出了高压绕组超导调相机的定子结构方案，并基于高压定子结构特点，开展了15 Mvar-35 kV高压绕组超导调相机的电磁设计；然后，以该调相机为研究对象进行电磁特性仿真及结构强度计算，从电磁方案的合理性及机械强度的可靠性两方面对高压定子方案的可行性进行验证；最后，研制分瓣高压定子样机，总结制造工艺要点，并对XLPE电缆绕组的绝缘可靠性进行试验验证。研究成果可为高压绕组超导调相机的工程应用提供理论支撑。
Using XLPE(cross-linked polyethylene) cables as stator windings in a superconducting synchronous condenser can significantly increase its voltage rating and enable direct grid connection. This novel configuration is referred to as a superconducting synchronous condenser with high-voltage XLPE cable windings(hereinafter “superconducting synchronous condenser with high-voltage windings”). First, a stator structural scheme for the superconducting 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 performance simulations and structural strength calculations are conducted for the proposed condenser, and the feasibility 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 summarized, and the insulation reliability of the XLPE cable windings is experimentally verified. The results provide theoretical support for the engineering application of superconducting synchronous condensers with high-voltage windings.
