Simulator for functional test of protective relay

摘要

The present invention relates to a simulator for the functional test of the protective relay, and in particular, a simulation signal generator for generating a possible fault environment simulation data; A simulation signal output unit for applying the simulated signal to the applied system; By constructing a personal computer (PC) unit that connects the two parts above, simulating possible situations, not only the existing fragmentary characteristic test but also the complex test of the protection relay applied to the system is possible, and also the data logger It is possible to apply the signal data generated in the actual field to the protective relay to be applied to implement the field test, and in particular, it is possible to edit and database the simulation data and the field data to provide various open environments of the protection algorithm applied to the protective relay. You can do it.
