The transient characteristics of a grounding grid is very important for the safety of the equipment on it, which is quite different from the performance at power frequency. In this paper, based on numerical simulation, the factors due to the grounding grid that affect its transient performance were discussed. The methods to improve the transient performance of the grounding grid such as increasing...
Integrating three-phase induction motor electromagnetic calculation program and multi-objective inverse optimization algorithm, a multi-objective & inverse three-phase induction motor optimization system with C++ is realized. This system can optimal design three-phase induction motor automatically. The design examples verify the effectiveness of the system.
To benefit the fault detection and identification of conductor corrosion fault, a hierarchical simplified model of grounding grids is put forward. Minimum unit dividing is the key process of hierarchical simplification, which can be realized by the proposed algorithm. Branches are classified into clear branch and uncertain branch. A Monte-Carlo based testability evaluation approach is suggested. The...
