摘要
电路的故障诊断在实际工程应用中占有重要地位,而故障定位是电路故障诊断的主要内容。本文对故障定位的经典方法进行了详尽的研究。首先将配电网设备物理模型转换成数学模型,然后再依据配电网拓扑描述法,对数学模型的分析推演而解决实际问题。应用结果表明,针对单故障源,该方法方便、快速、可行,但不适用于大规模设备的接入。
The fault diagnosis for electronic circuitry is very important in practical engineering applications-while fault localization is the maincontent of faultdiagnosis of circuitry, thus the fault localization is studied. Firstly, the physical model of the distribution network is transformed into a mathematical model, and then according to the topology description of the distribution network, the practical problems are solved by analyzing the mathematical model. The results show that this method is convenient, fast and feasible for single fault source, but it is not suitable for large-scale equipment intervention.
