Embodiment

[0034] like Figure 1-Figure 3 As shown, the system includes: data acquisition module, information processing module, analysis and calculation module, visual display module, intelligent alarm module, wherein: the data acquisition module respectively collects SV messages, device communication protocol messages and GOOSE The message is output to the information processing module. The information processing module parses the above message into analog quantity, switch quantity and protection logic information according to IEC61850 and device communication protocol, and performs application-oriented modeling processing based on IEC61131 to generate a relay protection design The operating state model of the principle is output to the analysis and calculation module based on PLC logic and protection action principle. The analysis and calculation module corrects the operation state model according to the protection action principle, and establishes information with logical relations to...

Abstract

The invention relates to a system for visually dynamically monitoring running state of a relay protector, belonging to the technical field of power supply distribution. The system comprises a data acquisition module, an information processing module, an analysis calculation module, a visual display module, and an intelligent alarm module, wherein the data acquisition module is used for respectively acquiring an SV (signature version) message, a protection device communication protocol message, and a GOOSE (generic object oriented substation event) message, and outputting the messages to the information processing module. According to the invention, the technician can visually observe the real-time running and action state of a protection device so as to determine the accordance degree between the action response property of the relay protector and the protection design requirement.

Description

technical field [0001] The invention relates to a protection device in the technical field of power supply and distribution, in particular to a visual dynamic monitoring system for relay protection operation status. Background technique [0002] With the rapid development of microelectronics, computer, communication and other industry technologies, it provides a basis for the application of microcomputer relay protection devices in power systems. As an important barrier for the safe operation of power grids, the correctness of relay protection actions will directly affect to the security and stability of the power grid. [0003] The application of the microcomputer relay protection device has brought advantages such as the convenience of the protection device inspection, but the microcomputer relay protection uses digital information processing technology to complete the protection action principle, which makes the logic schematic diagram visible in the original static relay...
