基于轨道同步进动特性分析了星链卫星系统Ⅰ期、Ⅱ期星座演化趋势,揭示了多Walker-δ子星座构型存在的问题,研究了星链Ⅲ期拟采用的回归共地面轨迹星座构型的实现机理,并对其覆盖特性进行了仿真分析。结果表明:不同倾角的回归共地面轨迹卫星链可以在轨道高度差异很小的情况下实现同步进动,相对于多Walker-δ子星座的构型具有构型更稳定、覆盖性能更优的明显优势,特别适合巨型低轨互联网卫星系统。该研究可为加速推进我国同类卫星系统建设提供借鉴。

多次短路会逐渐积累绕组机械损伤,最终导致电力变压器损坏。然而,目前缺乏一种量化评估方法来评估此类损伤,这对电网的安全运行构成了威胁。因此,该文提出一种考虑绕组的非线性特点和累积过程的电力变压器绕组短路累积机械损伤评价方法,为评估绕组短路对电力变压器的影响提供了新的途径。该方法采用阻尼比和可靠性损失系数作为特征量,通过指数型曲线来模拟绕组机械弱化过程。同时考虑变压器的初始承受短路的能力、短路电流幅值和故障次数等影响因素,量化了短路损伤与绕组动态机械寿命之间的关系。此外,通过对一台110 kV电力变压器进行多次短路破坏性试验,验证了该评价方法的正确性。最后,阐述了提出的评价方法适用于不同的校核控制方法,并强调了控制阻尼比在减少累积损伤方面的积极作用。

目前我国保险代理人(包括专属代理人和中介公司代理人)对寿险业保费收入的贡献超过50%。作为各公司保险代理人管理的基本纲要,保险代理人基本管理办法(基本法)通过对保险代理人的约束与管理,对公司经营目标的实现产生重要影响。本文对26家公司的基本法内容进行拆解整合,形成包含7个一级指标,30个二级指标,76个三级指标的基本法指标体系。运用层次分析法,在对保险公司管理人员、保险代理人和消费者调查的基础上,确定了指标体系权重,形成了基本法评估框架。基于这一框架,本文聚焦寿险公司经营中重点关注的业务规模、业务稳定性和保险投诉指标,阐述了基本法指标模块与寿险公司经营指标的传导机制,帮助寿险公司基于公司发展目标形成差异化且有针对性的基本法改革思路。
