基于故障字典法的电阻网络的故障诊断
|
摘要
该文根据电路开放实验的教学实践过程,研究了电阻网络故障诊断的故障字典法。针对一个简化的电力系统接地网电路模型,采用故障字典法建立了该电路模型中单一电阻发生任意故障时的故障字典。已知故障电压后,根据故障字典可以确定故障电阻的位置,利用KCL定律和欧姆定律可计算出故障电阻的阻值。最终借助MATLAB图形用户界面(GUI)设计了一个通用的故障诊断软件。实验通过"提出问题-讨论-独立解决问题"的指导方式极大地激发了学生对实验的兴趣,锻炼了学生综合运用电路知识解决实际问题的能力,提高了学生的自主学习能力及创新意识。
According to the experimental teaching practice process of circuit open experiment, this paper studies the fault dictionary method of fault diagnosis of resistor network. A fault dictionary of a single resistor in the circuit model is established by using the fault dictionary method for a simplified power system grounding network circuit model. After the fault voltage is known the fault resistance can be determined according to the fault dictionary. The resistance of the fault resistor can be calculated by KCL law and Ohm 's law. Finally,a general fault diagnosis software was designed with the help MATLAB Graphical User Interface(GUI). The experiment greatly stimulated students' interest in experiment through the guidance of "problem-discussion-discussion independent problem solving", and exercised students' ability to comprehensively apply circuit knowledge to solve practical problems, and improved the students' self-learning ability and innovation consciousness.
