The influence of system, so as to ensure the stability of power system.Simultaneously as direct current transportation, generation of electricity by new energy mode access power network, newly
Power grid architecture form new requirement is proposed to the selectivity of relay protection, quick-action, sensitivity, reliability.
Power system at present mainly carries out relay protection setting calculation work using computer, and in recent years, adaptive setting is soft
Part constantly improve, has for relay protection setting calculation and greatly helps.But with the access of generation of electricity by new energy mode, it is various
Adaptive setting program is again there is certain limitation, and in some cases, the definite value that adaptive setting software provides may be closed not enough
Reason, so increases potential safety hazard, on the other hand in view of power industry in whole national economy for power system
Critical role, avoid causing unnecessary harm to system operation, it is impossible to tested, therefore entered in real system
It is necessary that building electric power system model carries out simulating, verifying after row relay protection setting.
It is that domestic relay is protected to carry out pure software emulation currently with MATLAB or use relay protection synthesis experiment platform
Protect the common method of experimental teaching.For the pure software emulation using MATLAB, student is it will be appreciated that basic relay is protected
Principle and setting method are protected, but lacks subjective understanding for relay protection setting and line, is running into actual relay protection
Still had no way of doing it during device；And for using for relay protection synthesis experiment platform, relay protection experimental platform is typically adopted
With enclosed construction, in experimental teaching, student is only needed according to the intrinsic template wiring of experiment porch, and the corresponding parameter that carries out is set
Put, experimenter can not but understand experimental platform system internal structure, protection act sequence and signal processing flow.Above two
Mode student can not will once, second loop return wiring and effect effectively combine, therefore experiment effect is limited.

Case, power cabinet and general real-time simulator UREP DI mouths are connected to protective relaying device.
Host computer 1 and protective relaying device 3 are placed on experimental bench, general real-time simulator 5, Ethernet switch 4, work(
Rate cabinet 6 is installed in rack, and I/O boards 7 are also equipped with rack.
I/O boards include AI/AO boards and DI/DO boards.
A kind of emulation mode of relay protection teaching experiment simulation platform, this method are；Host computer passes through Ethernet exchanging
Machine and real-time simulator enter row data communication, and experimenter builds power system primary circuit in host computer, set breaker,
Abort situation and fault type, analogue simulation power system various faults state, in experimentation host computer by experimental model and
Data transfer is shown to display.
Power system modeling emulation uses MATLAB/Simulink mathematics libraries interface, and user selects according to their needs
Select corresponding component and realize function, and off-line simulation can be completed, the correctness of confirmatory experiment principle.
Beneficial effects of the present invention：Compared with prior art, relay protection teaching experiment simulation platform of the present invention avoids
Simple software emulation, while reduce teaching experiment cost again, and can also allow experimenter during teaching experiment
Participate in developing and utilizing protective relaying device, the culture to experimenter's knowledge applying ability and creativity consciousness, which has, greatly to be helped
Help.
