Problems solved by technology

For the pure software simulation using MATLAB, students can understand the basic relay protection principles and setting methods, but lack of subjective understanding of relay protection settings and connections, and still have no way to start when encountering actual relay protection devices; For the comprehensive experimental platform of relay protection, the relay protection experimental platform generally adopts a closed structure. During the experimental teaching, students only need to connect according to the inherent template of the experimental platform and set the corresponding parameters, but the experimenters cannot understand the experimental platform. System internal structure, protection action sequence and signal processing flow
In the above two methods, students cannot effectively combine the wiring and functions of the primary and secondary circuits, so the experimental effect is limited

Abstract

The invention discloses a relay protection teaching experiment emulation platform and an emulation method thereof. The relay protection teaching experiment emulation platform comprises a host computer, a universal real-time emulator UREP, an Ethernet switch, a relay protection device and a power box, wherein the host computer is connected with the universal real-time emulator UREP through the Ethernet switch; the AO port of the universal real-time emulator UREP is connected with the power box; and the power box and the DI port of the universal real-time emulator UREP are connected with the relay protection device. By adopting the relay protection teaching experiment emulation platform disclosed by the invention, simple software emulation is avoided, meanwhile, the teaching experiment costis reduced, in addition, experiment operators can join in development and utilization of the relay protection device in the teaching experiment process, and the knowledge application capability and the innovation consciousness of the experiment operators are greatly promoted.

Description

technical field [0001] The invention belongs to the technical field of semi-physical simulation teaching of electric power system relay protection, and in particular relates to a teaching experiment simulation platform of relay protection and a simulation method thereof. Background technique [0002] In recent years, my country's power system has developed rapidly, the scale of the power grid has continued to expand, and the scope and influence involved have become wider and wider. The safe operation of the power system has become more and more important. Under natural or artificial factors, a certain point or points in the power system will be in a fault or abnormal operating state. In this case, if the relay protection device can quickly detect the slight changes in the power system, and It can operate normally, which will reduce the impact of the fault location on the entire power system, thereby ensuring the stability of the power system. At the same time, as DC transmi...
