| 摘 要： | 以2个220 kV变电站接地网为模型进行接地网腐蚀诊断模拟试验.在初步诊断节点测量中分别采用大跨距、小分块和大分块结合不动点3种方案,列举出其诊断结果,并对3种方案进行分析、比较.结果表明了选择大分块结合不动点作为初步诊断时测量节点对的优化诊断法,诊断效率最高,效果最好.据此提出了接地网腐蚀诊断初步诊断时的选线原则,使该诊断方法更具工程实用性.

| Abstract: | Simulated experiments of grounding grid corrosion were conducted based on two 220 kV substation models.In initial diagnosis,the measurement nodal points were planned to great span,small piecemeal,and large piecemeal jointing fixed points.A comparative study of the three measurement plans was carried out.The results show that the large piecemeal with fixed points had the best performance and could be used as a practical method for diagnosing grounding grid corrosion. |
