Problems solved by technology

[0003] At present, most of the power systems have been equipped with advanced microcomputer relay protection devices, but a large number of relay-type experimental equipment are still used in school laboratories. Students can only understand the experimental principle by observing the action of the relay. It is not easy to deeply understand the relay protection algorithm by observing the current waveform and other parameters
In addition, because it does not match the actual application of engineering, the learning effect is also greatly reduced

Embodiment 1

[0032] This embodiment combines LabVIEW and MATLAB / Simulink to carry out the research and design of the virtual simulation experiment platform of relay protection, which can perform operation and demonstration of various types of relay protection experiments, and can also be used to study new protection algorithms or principles. The use of the LabVIEW virtual instrument allows the experimenters to break away from the hardware platform. Under the software development platform, each module of the system can be tested in time, which can improve the reliability of the protection performance. The system can simulate the fault environment in real time, monitor and analyze the action process of relay protection.

[0033] The power system fault transient simulation model is built in MATLAB / Simulink, and the interface between Simulink and LabVIEW is realized by using the built-in MIT (Model Interface Tookit) toolkit in NI VeriStand. The Simulink model generates C++ code through the MAT...

Abstract

The invention discloses a relay protection virtual simulation experiment teaching platform. The relay protection virtual simulation experiment teaching platform is composed of a fault simulation module, a relay protection simulation module and a man-machine interaction module. The experiment item setting is composed of a current protection experiment, a distance protection experiment and a transformer differential protection experiment. Students can remotely enter the virtual experiment platform through a webpage, experiment and interface selection are carried out after account password matching succeeds, then experiment operation is carried out according to experiment principles, experiment block diagrams and experiment requirements, fault types can be selected, fault parameters can be set, protection types can be selected, and the like. Data generated after the experiment is stored in a database through a data module and is used for generating a report. Compared with the existing experiment mode, the virtual teaching experiment platform not only can ensure the experiment teaching effect and improve the experiment efficiency, but also can save the investment, reduce the experiment cost, simplify the experiment system and improve the experiment teaching and scientific research effects.

Description

technical field [0001] The invention belongs to the field of experimental teaching, in particular to a virtual simulation experimental teaching platform for relay protection.
