Method and system for realizing relay protection and secondary circuit debugging visualization

Abstract

The invention relates to a method and a system for realizing relay protection and secondary circuit debugging visualization. The system comprises a testing signal generation system, a virtual protection device, a virtual secondary circuit and a visualization unit, wherein the testing signal generation system is used for generating testing signals; the virtual protection device is used for receiving the instantaneous quantity, the steady-state quantity or the positive-sequence, negative-sequence and zero sequence components of the testing signal generation system, generating a current switching quantity variable of logic diagrams for protection, tripping, reclosing and the like, and transmitting the current switching quantity variables to the visualization unit; and the visualization unit is used for extracting the current switching quantity variable of the virtual protection device, the new switching quantity variable of the virtual secondary circuit and a switching quantity variable produced through operation, and generating visualized action images. The method and the system for realizing relay protection and secondary circuit debugging visualization have the beneficial effects that the visualized action images are displayed through two ways, i.e. sampling-point-by-sampling-point control and period-by-period control, and the modules of the system are clear and the training and the learning are facilitated.

Description

technical field [0001] The invention relates to the field of relay protection and simulation of electric power systems, in particular to a method and system for realizing relay protection and secondary circuit debugging visualization. Background technique [0002] With the rapid development of relay protection technology, the functions of relay protection devices based on computer technology are becoming more and more perfect and powerful, which puts forward higher requirements for the theoretical level, practical operation level and fault analysis ability of relay protection workers . Relay protection personnel should not only operate the relay protection device correctly, but also be able to test various states of the relay protection device and analyze the test results. The wrong operation and analysis of the relay protection device will directly endanger the safe and stable operation of the power system. Once an accident occurs, the loss to the national economy will be ...
