modélisation de la génératrice asynchrone a double alimentation

本压缩包 包含 任务书、论文以及答辩ppt，虽说是课程设计，但是按照毕业设计书写，内容充实 本次课程设计主要是对象湖变的电网进行保护整定，对d1至d6共6个地方进行了最大方式与最小方式运行情况下的短路电流计算。计算完短路电流后，对L1至L5共5条线路进行电流保护整定。但是由于线路较短，线路阻抗较小。经计算后均不适合三段式电流保护。所以采取了纵联差动保护作为主保护，定时限过电流保护作为后备保护。对于变压器，采用纵联差动保护与气体保护共同作为主保护，过负荷保护作为后备保护。(The curriculum design is the object variable grid lake protection setting of D1 to D6, 6 places for the maximum and minimum operation mode under the condition of short-circuit current calculation. Calculation of short-circuit current after the end, L1 to L5 a total of 5 lines of current protection setting. But because of shorter lines, line impedance is small. The calculations are not suitable for three phase current protection. So take a longitudinal differential protection as the main protection, timing and limiting current protection as a back-up protection. For transformers, using longitudinal differential protection and gas protection as the main protection, overload protection as a back-up protection.)

一本关于介绍2015年发表的关于扩展有限元的SCI论文的论文集书籍，非常实用(In the standard FEM, cracks are required to follow element edges for the discontinuity modeling. In contrast, the crack geometry in the extended finite element method (XFEM) need not be aligned with the element edges and thus is independent of the background mesh.)

( 从太原市公交查询系统建立的必要性出发, 进行了公交查询算法的研究, 主要探讨了包括最短路径查 询及最少花费查询及数据库管理的公交查询系统的实现。 该系统采用了V ISU AL BA S IC 610 为开发工具, M ICRO SO FT A CCESS2003 为后台数据库, 开发了基于太原市公交线路的公交查询系统。具有线路查询、换乘 查询、 站点查询、 数据管理等一系列功能。 ((From the city bus system the need for inquiry, carrying out a public inquiry method of research, focused on the shortest path, including at least inquiries and inquiries and database management to spend the public inquiries system. The system uses a V ISU AL BA S IC 610 for the development of tools, M ICRO SO FT A CCESS2003 as the background database, developed based on the city' s public transportation bus lines inquiry system. with line inquiries, transfer information, site information, a series of functions such as data management.)
