Simulation and deduction system for complex power grid collapse and restoration process

摘要

The power grid large-scale blackout and collapse always puts our society in risk. Power grid companies must strengthen the ability to deal with blackout and collapse. The complex power grid collapse and restoration process simulation and deduction system is designed. System structure and system functions are described. This paper focused on the key technologies including power system simulation oriented to the collapse and restoration process, relay protection and automatic device simulation, and multi-agent simulation deduction. The system can achieve accurate and complete simulation of complex power grid collapse and restoration process, to reappear the whole process. It can provide simulation and training tools for power grid dispatchers and operators, to enhance the emergency ability to deal with power grid collapse.
