The power system fault simulation apparatus provided by the invention belongs to a novel technology, a novel product and a novel device in the field of safety protection of a power system and has great realistic guidance significance for scientific research personnel, professional technical personnel and onsite senior technicians in faults possibly occurring in the process of a power system, fault generation, fault phenomena and fault processing.

Description

technical field [0001] The invention relates to a power system fault simulation device. Background technique [0002] With the development of the economy and the increase of power demand, the scale of the power system continues to expand and the structure becomes more and more complex, and the safety and reliability of the power system operation are more and more highly valued by people. In recent years, large-scale power outages have occurred frequently due to local faults in the power system. Through the statistics of these power system power outages, it is found that these power outages are mostly caused by cascading faults. The cascading faults of the power system seriously affect the safe operation and reliable power supply of the power system, causing huge economic losses and social impact. It is of great significance to provide reliable evidence. Contents of the invention [0003] In order to study and solve the above power fault problems, the present invention pr...
