A CORROSION DIAGNOSIS APPROACH FOR GROUNDING GRIDS BASED ON TABU SEARCH ALGORITHM

摘要：

In order to detect the corrosion of grounding grids, a corrosion diagnosis approach based on Tabu search (TS)algorithm is put forward. A grounding grid is excited between couples of touchable nodes by a current source. Some voltages of touchable nodes are measured in each excitation.Minimizing the energy of the error between testing voltages and evaluation voltages is used as the index. The designed values of branches are used as the initial values. A Tabu list is formed for the branches. In each step of iteration, the resistance of each branch is increased and decreased with a certain value, respectively, forming a set of neighborhood. The aspiration criterion and stop criterion are adopted. An experimental grounding grid with sixty branches is used as an example to show the feasibility of the proposed approach. It is also shown that the proposed approach has the advantage of less sensitivity to testing errors.
