Abstract

The invention provides an online monitoring device and an online monitoring method for intelligent electronic devices. The online monitoring device comprises an Ethernet controller, an FPGA (field programmable gate array) controller, an output module, a switching input module, an RS485 communication module and a power module, wherein the switching input module is in one-way connection with the FPGA controller, the Ethernet controller and the RS485 communication module are in double-way connection with the FPGA controller, and the FPGA controller is in one-way connection with the output module. The online monitoring device achieves analog simulation of operating environments of intelligent circuit breaker primary devices and is powerful in interaction function, convenient to operate and universal in interface. The online monitoring method has the advantages that experimental costs are reduced while experimental period is shortened; the online monitoring method is high in system expandability, thereby being applicable to performance monitoring of current rapid intelligent electronics development technology.

Description

technical field [0001] The invention belongs to the technical field of intelligent substations, and in particular relates to an online monitoring device and a monitoring method for intelligent electronic equipment. Background technique [0002] Substation equipment is the basic unit of the power grid. The intelligentization of substation equipment is an important part of the smart grid, and it is also one of the main signs that distinguish the traditional grid. The smart substation automatically collects and analyzes the status parameters of the substation equipment through the online monitoring system, realizes status visualization, evaluates and analyzes the equipment according to the status of the equipment, and takes corresponding countermeasures to realize the intelligentization of the substation. With the development of UHV transmission technology and smart grid technology, the demand for monitoring technology of substation equipment is increasing, and the performance...
