Power system fault simulation in SG-OSS DTS

With the increasing complexity of grid dispatching, it becomes an inescapable trend to implement a full dynamic simulation of DTS while fault simulation is a key component in dynamic simulation. This paper describes the design and implementation of fault simulation in a new generation of DTS based on multi-threaded multi-core processor architecture of parallel computing algorithm. Firstly describes the core design calculations for the fault, then describes the characteristics and features of fault simulation in the DTS environment. A numerical example was given to show the feasibility and practicability in large-scale power grid.
