18 13. PIXIT for Time synchronisation model Tm1 1 What time quality bits are supported (may be set by the IED) Tm2 1,2 Describe the behaviour when the time server(s) ceases to respond LeapSecondsKnown ClockFailure ClockotSynchronized The ABB 670 series can have 2 configured STP Servers. If the first fails, the second is taken into use. There is an automatic switch back if an erroneous one comes operable. If all STP servers are off-line the event timestamps get ClockFailure and ClockotSynchronized status. The STP servers are polled with an interval up to 64 seconds. If the STP server don t respond two extra tries will be done with short interval. After that the second STP server is polled. If no backup server is defined, there is a timeout of 5 minutes. What is the time server lost detection time Tm3 1,2 How long does it take to take over the new time from time server Tm4 1,2 When is the time quality bit ClockFailure set Tm5 1,2 When is the time quality bit Clock not Synchronized set The server is polled with an interval up to 64 seconds and after that polled with short interval 2 times more, so up to 67 seconds Depends on how much the time differ, from 2 seconds to 10 minutes. Upon start of the IED, until synchronization is received. As the time system is selfadjusted, the clock failure is set when the estimated deviation exceeds a certain value. Due to the good internal accuracy, this deviation occurs in the order of > 30 days. When connection to all time servers is lost (see PIXIT-Tm2) ABB Power Systems, SA Products 1MRG A en 18/21
