严重的洪涝灾害威胁着受灾地区的居民生命安全,及时的人员安置与物资保障有助于降低自灾害带来的负面影响。本研究对洪涝灾害预警时期的人员安置与物资配送两项工作进行共同考虑,由人员安置方案确定各地的物资需求量,作为物资配送优化的基础,最终得到一套联合工作方案。本研究以人员转移时间最短、人员未转移惩罚最小、物资未满足比例最低为目标,建立了该问题的数学模型。在时间划分上,本研究将应急物流工作的时间划分为多个等长的周期,并将每个周期划分为一段工作时间和一段休整时间。在工作时间内,车辆可以连续进行多次行程,以实现载具的最大化使用;在休整时间内,车辆不开始配送任务,以此应对计划外耗时带来的影响。最后,本研究基于安徽省阜阳市的蓄洪区位置构造算例,并使用遗传算法对算例求解,通过对比“联合优化”方案与“就近安置”方案,证实了人员安置与物资配送的联合优化能够让应急工作在整体上达到更好的效果。

虚拟同步发电机(Virtual synchronous generator,VSG)通过引入转动惯量(J)与阻尼系数(D_(p))模拟同步发电机的机电特性,有效地提高了分布式电源接入电网的稳定性。由于VSG中的J和D_(p)可以动态调节,通过对VSG进行小信号模型分析,分析了J和D_(p)对系统动态性能的影响。根据功角特性曲线分析了振荡周期中J和D_(p)的整定原则,提出了一种参数自适应控制策略,建立了J和D_(p)的自适应控制函数,使VSG在功率和频率输出具有更加良好的动态性能。最后通过Matlab/Simulink搭建仿真模型进行验证,仿真结果验证了自适应控制策略的可行性。

针对微电网并网时的电流冲击、电压畸变、功率振荡的问题,提出了一种基于无锁相环(PLL)的虚拟同步发电机(VSG)离并网切换控制策略。建立了VSG的控制模型。然后,在离并网切换的过程中,设计了一种无PLL的预同步控制单元,省去了PLL环节,避免了PLL对系统控制精度以及响应速度的影响,简化了控制算法,缩短了预同步的时间,加速了离并网切换过程。同时直接将角频率差值反馈回功率环,避免了Δθ符号跳变对控制过程产生的影响,并引入了积分抗饱和环节以加速调节恢复过程。最后进行了仿真验证,验证了该控制策略的可行性。

面对错综复杂和快速变化的商业环境,组织要想做出快速响应,领导者的有效倾听显得非常重要。通过文献综述发现,现有研究尚未对领导倾听的概念形成统一界定,且理论视角和研究层次较为单一,这不利于我们深入理解领导倾听的内涵及其多层次效应。事实上,作为一种领导行为,领导倾听不仅会对领导者自身产生影响,而且会给团队及其下属带来影响。因此,本研究基于二元互动情境,从沟通信息和支持员工两方面对领导倾听的内涵进行探索性研究,并从领导力效能的评价对象(领导者、团队、员工)出发,结合多层次、多理论、多研究方法的全景研究范式逐步揭示领导倾听对不同对象的不同效应、黑箱机制及边界条件。本研究不仅开拓了倾听研究的新思路和新视角,而且为企业增强领导倾听的积极效能提供了管理启示。
