摘　　要：本文针对目前超导应用系统中广泛采用的螺线管型超导磁体的设计问题,提出了综合考虑磁体储能、漏磁和体积的优化问题。以单螺线管磁场计算为基础,用矢量叠加的方法计算多螺线管磁体的漏磁和最大磁场,从而建立了用于优化的螺线管型超导磁体的电磁模型。借助多学科优化设计软件Isight,采用全局搜索和传统数学规划相结合的优化方法,对所建立的电磁模型进行了优化计算。结果表明应用这种组合方法进行螺线管型超导磁体电磁优化,能取得满意的结果。On loop power net, it is hard to obtain the system impedances at both sides of double circuit line that makes fault calculation difficult. An accurate Calculation method for random faults of double circuit line on loop net is introduced. By a precise model of distributed parameters and eigenanalysis method, considering the effects of power line transposing and distributed capacitance, the calculation method can precisely get random fault （including crossing lines faults and complex faults） results of double power lines on the same tower. With an example of two lines short and grounding fault, and one side of breaker of grounding fault line being cut off, the paper illustrates the principle of this calculation method.
