Python实现 IEC-61850 GOOSE和SV 实现

# IEC-61850 GOOSE and SV with Scapy An implementation of IEC-61850 GOOSE and SV with Scapy without the use of the built in BER. ## Why didn't you use Scapy's BER? For my application, I wanted to have full control over all bytes within the packet. While this may not be useful for all implementations, it worked well for me. ## What still needs to be done? * The PhsMeas portion of SV ASDU packets is not complete. * Validate on hardware. Current testing only utilized wireshark and libiec61850 * Hope to add MMS capability. (Need documentation however.)
