Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0030] The present invention is based on FPGA intelligent substation network storm solution method, such as figure 1As shown, the physical layer chip is connected to the upper layer program through the receiving control module set in the FPGA; as figure 2 As shown, the receiving control module includes a receiving control state machine, a subscription message parsing and judging module, a receiving byte counting module and a CRC check module; the receiving byte counting module includes a byte counter and a frame interval counter; image 3 As shown, the network storm solution includes the following steps,

[0031] 1) The receiving control module assigns the 2-bit Ethernet data frame received from the physical layer chip and the effective signal of the 2-bit Ethernet data frame to the receivi...

Abstract

The FPGA-based intelligent substation network storm processing module and its solution method of the present invention analyze the configuration information from the upper layer program through the receiving control module, reasonably distribute the analyzed configuration information to the sub-modules in it, and each sub-module quickly judges the reception through the configuration information Whether the received message is consistent with the message subscribed by the upper-level program, and then output the judged information to the receiving control module for summary output, and finally the receiving control module judges whether to send this frame to receive the message, so as to achieve in any network situation The lower IED can run safely, quickly and stably. By quickly processing Ethernet messages at the physical layer, the program burden of the application layer can be greatly reduced. Through the rapid identification and analysis of the messages, one frame can be judged at the same time after receiving one frame of messages, which can greatly reduce the internal data buffer. In order to achieve a reasonable use of internal resources, the IED can quickly identify reliable actions under the influx of a large number of network packets.

Description

technical field [0001] The invention relates to the field of intelligent substation network communication, in particular to an FPGA-based intelligent substation network storm processing module and a solution method thereof. Background technique [0002] Smart substation is an important link in the construction of smart grid, and the most common network structure of smart substation is the "three-layer two-network" networking structure. The three-layer includes station control layer, interval layer and process layer; Control layer network. With the development of my country's smart grid, the digitalization of information in the entire smart substation and the networking of communication platforms have become new requirements for the construction of smart substations in my country. At the same time, more and more IEDs (Intelligent Electronic Devices) are beginning to connect to the network. Among them, the networking of the communication platform not only brings the advantage...
