Abstract
The invention discloses a digital substation process level data exchanging device. The core of the device is a configurable data exchanging module based on the FPGA. A simple and efficient data exchanging mode is achieved on the basis of IEC61850. The unique functions of SV message rated delaying automatic updating, GOOSE deflected message prior transmission, data storm rapid accurate restraint and the like are particularly achieved. The problems that the process level SV networking communication depends on GPS synchronization, the transmission and delay of the GOOSE are uncontrollable and even packet loss occurs under the mode that the SV and the GOOSE are combined in network, and the storm restraint time is over long are solved. The motion delay of tripping operation of the GOOSE is reduced. The digital substation process level data exchanging device is creative, practical and economical and capable of promoting the reform of a digital substation process level networking mode.
