Abstract: To separate a large-scale grounding grid into several small-scale blocks to diagnose,respectively,a block model is put forward.The concepts of autonomy unit,non-autonomy unit,related,block and its prototype,projection of blocks,part of touchable node and set of considered intrinsic branches are defined.The principle of block dividing and the classification of blocks are discussed.The programming to realize the block model of a grounding grid is described.The way to identify the autonomy performance is detailed.An experimental grounding grid with sixty branches is used as an example.The proposed approach is shown feasible.

Key words: grounding grids, corrosion diagnosis, block modeling, programming

摘要: 为了将一个大规模接地网拆分为许多相互独立的小规模块分别进行诊断,提出了接地网的分块模型,定义了自治单元、非自治单元、相互关联、块及其原形、块的投影、分区和待求本征支路集合等概念,论述了块的划分原则和块的分类。论述了实现接地网的分块模型的程序流程,建议了一种自治性判断方法。以一个60条支路的实验接地网为例进行了详细说明,表明所建议的方法是可行的。
