A protection system using a multi-agent concept for power distribution networks is pro- posed. Every digital over current relay(OCR) is developed as an agent by adding its own intelli- gence, self-tuning and communication ability. The main advantage of the multi-agent concept is that a group of agents work together to achieve a global goal which is beyond the ability of each individual agent. In order to cope with frequent changes in the network operation condition and faults, an OCR agent, proposed in this paper, is able to detect a fault or a change in the network and find its optimal parameters for protection in an autonomous manner considering information of the whole network obtained by communication between other agents.Through this kind of coordi- nation and information exchanges, not only a local but also a global protective scheme is com- pleted. Simulations in a simple distribution network show the effectiveness of the proposed protec- tion system. 相似文献

2009年,安徽中医药大学与韩国顺天乡大学合作开办计算机科学与技术本科专业“2+2”项目。在双学历合作培养模式下,学生的韩语水平对于本科阶段的学习具有重要的影响。韩语教学质量直接影响中韩合作办学项目目标的实现。韩语教师在教学实践中需要不断摸索和总结提升韩语教学效果的方法,以实现与韩国大学的培养模式准确对接。作者通过学习并借鉴韩国顺天乡大学韩国语专业教师的教学方法和模式,提升安徽中医药大学韩语教学效果和学生实际运用韩语的能力,激发学生的学习热情和积极性,培养学生的跨文化适应能力。 相似文献

改进了一种从头计算方法—共轭梯度方法 ,研究了超晶格 Ga As/ A lx Ga1 - x A s的电子结构 .根据超晶格的基本方程 ,在固定电子密度 n(z)下 ,求解了基本方程的本征值和本征函数 ,并由它们组成新的 n(z) ,重复此过程直到得自洽解 .另按超晶格基本方程的具体情况 ,对每个 kz独立地应用了共轭梯度方法 ,此可大大节省与 Gram-Schm it正交化有关的时间 .计算了超晶格的两个最低子能带之间的能量差和 F ermi能量 ,其模拟计算的结果与对应的实验数值一致 相似文献

The toxicity of asbestos has been constantly an active research topic. Although asbestos has lots of advantages owing to its stable physicochemical properties and economic characteristics, nations enforce policies prohibiting or limiting its use because of its critical impact on human health. Especially in Korea 96% of imported asbestos are slate construction materials and with the influence of Saemaul movement, thatched roofs have been drastically replaced with slate roofs. Efforts to know the distribution characteristics of extensively used asbestos cement slates and to find out the removal method that suits the distribution characteristics are still in an insufficient state. The purpose of this work was to probe into the distribution of asbestos cement slate buildings in Korea and provide basic data of distribution characteristics for policy making in which consideration of the differences between rural and urban regions is necessary based on findings of the studies so far. It is considered helpful in many ways to solving asbestos cement slate related problems in countries where asbestos usage is increasing even after the 2000s including China. 相似文献

表动作趋向的介词"向、往"是学汉语的韩国学生在使用方面偏误率较高的介词之一。本文对韩国学生使用"向、往"的情况进行了调查,分析干扰韩国学生掌握使用介词"向、往"的原因,并从本体和汉韩对比两个角度对"向、往"这两个介词做出较为细致的比较,从多个角度得出对韩国留学生进行介词"向、往"教学的一些启示。 相似文献
