The analysis of protection action evaluation based on setting calculation system

Aiming at the limitation of the accuracy existing in the traditional treatment method basedon the equipment fault location, on the basis of the fault information system and setting calculationsystem, puts forward the evaluation and analysis method which combining with simulation algorithmand expert system to achieve protection action, acquires power grid mathematical model through theinterface with setting calculation system, adopts fault distance detection to realize fault location,improves the accuracy of fault localization, and lays the foundation for the accurate evaluation of theprotection action. The research result shows that the evaluation result of protection action by thismethod acquired is accurate, and can apply to other power grids.
