三相同步发电机运行仿真与GUI设计 摘要 摘要 同步发电机是电力系统的能量提供者，它的控制性能的好坏将直接决定电力系统的安全与稳定运行状况。所以检测同步发电机的运行状态具有重要意义。 首先了解同步发电机的基本概述，国内外发电机的发展现状及趋势，同步发电机的运行原理、数学模型及主要的工作特性。然后介绍三相同步发电机的运行原理，并就其对称运行与不对称运行进行分析。应用M文件或者Simulink对电机的运行状态建立模型，得到相应的仿真图形。运用GUI工具制作一个“电机仿真试验系统”界面，通过登陆界面之后，进入统一的用户交互界面，来选择电机类型、实验项目，并借助MATLAB的支持，进行试验仿真。 本文对仿真的实例进行分析，证明了此种方法的可行性，所得到的仿真结果符合电机的运行状态。 关键词：同步发电机；运行状态；数学模型；对称；不对称；GUI；电机仿真。 I Abstract Three-phase synchronous generator running simulation and GUI design ABSTRACT Synchronous generators in power systems energy provider, control performance is good or bad it will directly determine the power system security and stability of operating conditions. Therefore, the operation status of detecting synchronous generator is important. First of all know the basic outline synchronous generator, the development situation of domestic and foreign generator and trend, operating principle of the synchronous generator, mathematical model and the main work characteristics. Then introduces the operation principle of three-phase synchronous generator，and to the symmetric and asymmetric operation to run the analysis. Applications of M files or Simulink to model the motor running, get the corresponding simulation graphics. Using GUI tool to make an motor simulation test systems interface, through after landing interface, entering unity of user interface, to choose the motor type, experiment project, using MATLAB support , test simulation. This paper analyzes the simulation of the examples, proved the feasibility of this method, the simulation results with meet running state of the motor. Keyword: Synchronous generator；operation status；mathematical model；Symmetric； asymmetric；GUI；Motor simulation。 II 目录 目录 摘要.............................................................................................
