用于电力系统故障电流限制器的快速合闸开关研究

This paper presents a new type of fault current limiter(FCL) based on fast-closing switch,which is composed of a capacitor bank and a reactor in series.The main control component is a fast-closing switch connected in parallel with the capactitors,which is drien by the electromagnetic repulsion force.It can response the order within 1 ms.When fault occurs,the switch closes and the capacitors are bypassed.and the fault current is limited by the reactor,Simulation analysis and experiment show that the electromagnetic repulsion force actuator can meet the demand of fast-closing switch,it is feasible to develop the FCL with low cost and high reliability.     

集装箱多式联运下“隐藏损害”赔偿责任之研究

集装箱运输下整箱货的“隐藏损害”是当前从事集装箱运输业的人们所共同关注并迫切希望得以解决的问题,但由于涉及的当事人众多,相关适用的法规较少,因而在一定程度上难以得到公正的解决。本文试图运用具体相关条款,结合较典型的案例对“隐藏损害”责任之确定加以叙述,从而对整箱货运输下“隐藏损害”的处理有所借鉴。     

基于FCL模型的师范生教学实践性知识学习共同体研究

为了改变当前高等师范教育中师范生教学实践性知识获得的单一、线性模式,构建了基于FCL模型的师范生教学实践性知识学习共同体。通过为期半年的实验研究发现,基于FCL模型的师范生教学实践性知识学习共同体能够有助于师范生更好地获得教学实践性知识,尤其是教学设计性知识,但尚不能提高师范生教学技能和灵活性。同时研究表明,师范生完成优质的课堂教学设计能够有助于提升课堂教学实施能力。     

真空触发开关故障电流限制器的研究

A new type of fault current limiter (FCL) based on triggered vacuum switch (TVS) is proposed in this paper. The TVS-based FCL (TFCL) is mainly composed of a capacitor, a current-limiting reactor connected with a capacitor in series and a TVS connected with a capacitor in parallel. With the TVS at off or on state, the whole TFCL behaves as a conventional series compensator or a fault current limiter, respectively. Numerical simulation and prototype experiment based on LC resonant test circuit show that it is feasible to develop TFCL.

探究型合作学习模式案例评述

探究型合作学习越来越受到大家的重视,它是以探究为核心,以过程为重点,引导学生进行合作学习的一种有效的学习手段。小组调查和FCL都是探究型合作学习的典型模式。     

家用电器模糊控制开发平台的研究

本文对家用电器模糊控制开发平台进行分析与设计。平台利用IEC 61131—7中定义的FCL（Fuzzy Control Language）语言描述整个模糊控制系统，并且同时可自动生成标准C语言或其他高级程序设计语言描述的模糊控制系统的程序代码。应用该家用电器模糊控制开发平台大大提高了模糊控制系统设计质量，缩短设计时间。
