Embodiment Construction

[0042] Combine below figure 1 The present invention will be described in detail with specific embodiments.

[0043] figure 1 Shown, the overall conceptual block diagram of this invention. It consists of two main CPUs, namely CPU1 and CPU2. The two CPUs can be two computing cores of the same physical CPU, or two independent CPUs.

[0044] Among them, CPU1 is mainly responsible for the configuration of the MAC controller of the GOOSE and SV receiving network ports and preliminary filtering of the received GOOSE and SV messages. Among them, CPU2 is mainly responsible for processing the GOOSE and SV data filtered by CPU1, and this CPU is also responsible for transmitting the configuration information of GOOSE and SV to CPU1. The data connection between the two CPUs can perform data interaction through the internal Ethernet channel or shared memory.

[0045] hardware filtering, such as figure 2 shown.

[0046] In the first step, CPU1 sets the registers of the associated MAC...

Abstract

The invention discloses an intelligent substation process level device network windstorm restraining method. The method includes adopting a CPU1 and a CPU2 to process network messages of GOOSE and SV, wherein the CPU1 is used for filtering the network messages of GOOSE and SV, and the CPU2 I used for processing logic content of the network messages of GOOSE and SV. By means of multistage filtering of the messages of GOOSE and SV, network windstorm filtering of GOOSE and SV is achieved, stable quick loss-free network windstorm filtering can be conducted on an intelligent process level device based on CPU, and the requirements of the intelligent grid process level device for quick treatment of messages of GOOSE and SV under network windstorm can be met.

Description

technical field [0001] The invention belongs to the technical field of electric power automation and communication, and relates to a network storm suppression method for process layer equipment in an intelligent substation. Background technique [0002] In the current intelligent substation process layer network, the interaction of GOOSE and SV messages between devices is usually transmitted in a point-to-point or switch mode. When devices are connected by switches, due to switches, loops or faulty devices can cause network storms. When devices are connected point-to-point, a device may generate a large number of fault messages due to device failure, causing the receiving device to receive network storm data. [0003] In the case of the transmission of these two modes, there are cases where the Ethernet network storm is affected. Due to the particularity of the process layer equipment, the equipment needs to be able to quickly process GOOSE and SV packets that are not affe...
