船舶电力系统短路电流计算软件开发本科毕业论文.doc

摘 要 随着舰船向着大型化、自动化的方向发展，对船舶电站的要求越来越高，为了适应未来全电力推进船的电力性能及可靠性的要求，船舶电站的供电网络形式也将会出现多种多样的变化，其中对干馈混合式配电方式的研究是非常重要的一个部分。本文的重点是船用干馈混合式配电方式电力系统暂态稳定性中短路电流的研究。船舶电力系统短路电流的计算软件是根据船舶交流电力系统的短路电流是交流同步发电机和异步电动机的短路电流叠加的原理，并根据国家标准GB3321-82《船舶交流电力系统的短路计算》的有关规定和计算方法，对交流电力系统发生三相对称短路后第一个半周期的对称短路电流和最大非对称短路电流的计算。在windows环境下采用计算机高级语言Visual Basic6.0开发的软件。该软件支持对数据的浏览和修改功能，提供友好的操作界面，是完全的事件驱动的程序。 关键字：船舶；电力系统；短路电流；软件开发 Abstract With the fact that ship and warships are developing towards the direction of large-scale and automating, the call for the ship power station is higher and higher. In order to adapt to the electric power function and reliability for the future of the All-electric propulsion ship, the Network Power supply ship also will be a variety of forms of change, Among them, the research of The ship with feeds dry the mixed style power distribution way is a very important part. This article key point is the research of the short-circuit current in the mixed style power distribution way electrical power system transition condition stability of The ship with feeds dry the mixed style power distribution way. the software of short-circuit current calculation to the Ship power system is based on the principle that short-circuit current to the exchange of power system of ship is the superposition of short-circuit current for AC synchronous generators and induction motor , and according to the regulation and reckoning of the national standard GB3321-82 short-circuit calculation for the exchange of power system of ship, Calculation to symmetrical short-circuit current and maximal asymmetric short-circuit current for the first Period of the three-phase exchanging symmetrical short circuit of electric power system occurrence, this Software adopt high-level Keywords: Ship; Power Systems; Short-circuit current; Software development 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc232397519 第一章 绪 论 PAGEREF _Toc232397519 \h 1 HYPERLINK \l _Toc232397520 1.1 船舶交流电力系统 PAGEREF _Toc232397520 \h 1
