2, Netcom's communication method (explanation as shown in Figure 1)
1) message receives (message of current reception belongs to consolidated network with the last message that receives):
If the message ST numbering that the message ST of current reception numbering received more than or equal to the last time, message is effective.
If the message ST numbering that the message ST of current reception numbering received less than the last time, and error is smaller or equal to 3 o'clock, and message is invalid.If there is the MAC route on the network, because difference or other cause specific of routing algorithm exist the communication packet that sends earlier to lag behind the communication packet that the back is sent out in theory.Be difficult to during GOOSE uses occur, can determine whether this phenomenon is handled in the development process as required.Analyze by going up with practice in theory, even there is the MAC route in GOOSE in using, can not surpass 2 grades of routes at most, so the communication packet hysteresis should not surpass 3 bags
If message ST numbering that the message ST of current reception numbering received less than the last time and error were greater than 3 o'clock, message is effective.This phenomenon only may occur in that dispensing device is restarted or message numbering is overturn, the sort of situation no matter, and message all should be effective.
2) message receives (message of current reception does not belong to consolidated network with the last message that receives):
If the message ST numbering that the message ST of current reception numbering received greater than the last time, message is effective.
If the message ST of current reception numbering equals the last message ST numbering that receives, message is invalid.
If the message ST numbering that the message ST of current reception numbering received less than the last time, and error is smaller or equal to 100, and when two nets were worked simultaneously, message was invalid.According to snowslide test, when dispensing device simultaneously after two networks send communication packet, there are many parts of messages that lag behind another network in the communication packet of certain network.(as: dispensing device sends simultaneously 3 parts of messages in two nets because the offered load difference, exist receiving system to receive whole 3 parts of messages of a certain network after, just receive first part of message of another network).
If the message ST numbering that the message ST of current reception numbering received less than the last time, and error is smaller or equal to 100, and when two nets were not worked simultaneously, message was effective.This phenomenon occurs in receiving system receive the A of dispensing device (B) network packet after, dispensing device restarts, restarting back A (B) net because some reason is no longer worked, receiving system can only receive B (A) network packet, and the cause that the ST numbering restarts because of device in B (A) the Netcom news message, count from zero, this moment, message should be effective.
If the message ST numbering that the message ST of current reception numbering received less than the last time, and error is greater than 100 o'clock, and message is effective.This phenomenon only may occur in that dispensing device is restarted or message numbering is overturn, the sort of situation no matter, and message all should be effective.
3) message sends: communication packet,, sends by trigger mechanism if protective device exists protection action launching or involution order, measure and control device to have the startup or the involution order of the action same period by two net timed sending in real time according to configuration.(GOOSE mechanism regulation, when data changed, the ST numbering in the communication packet added).
