The invention relates to detection equipment and a detection method for network storm. The detection equipment is equipment in an intelligent substation and comprises a microprocessor, a register and a field programmable gate array which are connected in sequence, wherein the microprocessor is used for obtaining a preconfigured network storm configuration file, analyzing the network storm configuration file, obtaining network storm configuration information according to an analysis result and writing the network storm configuration information into the register; the register is used for storing the network storm configuration information; the field programmable gate array is used for reading the network storm configuration information from the register and outputting single-frame messages to a plurality of to-be-detected equipment in the intelligent substation through a plurality of sending ports according to the read network storm configuration information in order to carry out online network storm detection on the to-be-detected equipment. According to the detection equipment and the detection method, the equipment cost of network storm detection can be saved when the coexisting environment of the complicated multi-format messages in the intelligent substation is simulated.
Description
technical field [0001] The invention relates to the field of substation intelligent automatic safety devices, in particular to network storm detection equipment and a network storm detection method. Background technique [0002] The communications of the interval layer, process layer and station control layer of the smart substation are all digital signals. The stability of device communication is an indispensable part of a substation, and is closely related to protection, measurement and control, measurement and other links. In engineering applications, because there is a networking mode for communication between the process layer, the station control layer, and the interval layer, this communication method must pass through a switch, so the networking and other links will be affected by network storms and error frames. Network storms and various error frames have seriously affected the reliable operation of equipment in the station. Therefore, there is an urgent need for...
