Research and development of simulation and training systems of protective relaying based on component

This paper introduces a simulation and training systems of protective relaying based on competent technology, which takes fault filter data and simulation data as data sources. Visual C++ programming language is used for data modeling base on IEC61850 standard. A base model describing the function of protection and control devices and the principle of action logic and its training applications are built using visual interface. The design of the simulation system, the implementation method of various protection models and application are discussed. Simulation results show the flexibility of the proposed simulation system. The simulation results of the simulation system are accurate, reliable, intuitive and clear, which can be used for the protection operation staff training.
