 交流电机型式实验及计算机软件的研究

 摘  要：交流电机型式试验及计算机软件的研究主要包括以下几个部分：第一章，概括讲述了自动测试系统当前的发展概况和特点；第二章，说明了电机参数测试的基本原理和主要使用的测试方法，；第三章，详细讲述了交流电机型式试验的方法；第四章，详细讲述了微机在测试系统中应用的原理和结构，以及硬件的配备原则。第五章，详细介绍了自动测试系统软件的设计思路，使用流程图进行说明。这种试验系统与传统的试验方法相比，它的突出优点主要表现在：首先它缩短了试验时间，提高了试验效率，减少试验工作量；其次它的试验可靠性更高，测试的数据更精确，能自动对现场物理量进行实时采集、保存、处理与显示；再次，因为它是通过各种先进的传感器，所以能轻易获得一些不可直接测量或很难人工测量的技术参数；最后由于该系统能实时的自动生成试验报告显示并打印，因而就省去了人工记录试验结果这一过程，这也有利于工作效率的提高。

  The Alternate Current Electrical Machine Experiments and the Research of the Computer Software
 
 [ABSTRACT]：Electrical Motor Automated Testing System developed with the development of PC, Logic Control Device and Intelligence Measure Instrument. With the motortechnology developing, many different type motors are applied wider and wider, suchas the Frequency Motor and Synchronal Perpetuation Magnetism motor, so higherquality motor test system is required.
     This thesis presents PC-Base Model Motor Automated Testing System whosecontrol part is consisted of PC and Programmable Logic Device (PLC): PC controlsthe test process, Intelligence measure Instrument; the PLC executes the commandssent from PC. Common Three-coil Motor, Frequency Motor, Synchronal Perpetuation Magnetism Motor can be tested by this system.
  Firstly, this thesis compares this automated system hardware structure with thoseof  some others, and analyzes the virtues and defects of these systems' hardware structures. Secondly, this thesis introduces the motor test methods according to nation motor test standard and ministry motor test standard, introduces the algorithm of automated test process, and analyzes Frequency Motor automated test to a certain extent. At the same time, this thesis introduces the design of the system software, and the way of dealing with, saving, output the measured data. At last, this thesis gives the way of improving the system, and with the combining with the foreign test system, discusses the trend of motor automated test system
