It should be noted that the present invention is a kind of distribution power automation terminal based on intelligent distributed principle, during work：Intelligence point
Startup, protection act, switch point/conjunction position, switch failure, reclosing is protected to go out by GOOSE real-time exchanges between cloth DTU
The relevant information for network protection such as mouth, post reclosing acceleration action.
（1）" hand in hand " circuit, below figure 6：
Using " both take one " logic；
Trouble point occurs at F1；K6 detects fault current（Switch is closing position）, K7 do not detect fault current（Switch exists
Close position）, one has a fault-free information, that is, think trouble point between this two switch；K5 detects fault current（Switch exists
Close position）, K6 also detects that fault current（Switch is closing position）, both faulty information think that trouble point two is respectively opened at this
Outside the region of pass；Trouble point occurs at F2；K6 and K7 do not detect fault current（Switch is closing position）, do not have both
Fault message, that is, think trouble point in the outer of this two each switch.
Trouble point occurs at F3；K7 detects fault current（Switch is closing position）, L1 do not detect fault current（Open
Close in a point position）, one has a fault-free information, that is, think trouble point between this two switch.
（2）" T " link, below figure 7：
Using " three takes one " logic；Exchange protection startup between DTU, protection act, switch point/close position, switch failure,
The information such as reclosing outlet, post reclosing acceleration action.
Trouble point occurs at F4；K1 detects fault current（Switch is closing position）, K2 do not detect fault current（Open
Close and closing position）, K3 do not detect fault current（Switch is closing position）, three middle faulty information of only one of which, that is, think therefore
Barrier point is on " T " contact；
Trouble point occurs at F5；
K1 detects fault current（Switch is closing position）, K3 detects fault current（Switch is closing position）, K2 does not detect former
Barrier electric current（Switch is closing position）, there are two faulty information in three, that is, think trouble point outside " T " contact；
Trouble point occurs at F6；
K1, K2, K3 do not detect fault current（Switch is closing position）, three all without fault message, that is, are thought trouble point
Outside " T " contact；
End switch；" directly judging " logic；Below figure 7：
Trouble point occurs at F7；K8 switches are switched for line end, if K8 detects fault current, directly judge K8 downstreams
It is faulty；Whether " end switch ", can be adjusted as device definite value；
The independence of the sense of current；Below figure 7：
First time, trouble point was at F6, and the outlet A of K1 and transformer station is switched off, and F6 failures are isolated；Load transfer, remote control is closed
The non-faulting region load of lock interconnection switch L1, outlet A turns to be powered by outlet B；If now F4 points break down, K3 is detected
Fault current, K1 does not detect fault current, and K2 does not detect fault current, and according to " three takes one " logic, " T " connects
Point breaks down；
Analyzed more than, judgements of the DTU to failure is not rely on the direction of fault current at K3；
（3）Both the above fault handling time is calculated as follows Fig. 8, fault handling time definition such as Fig. 9 in Fig. 8.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
Although being described in detail to the present invention with reference to the foregoing embodiments, for a person skilled in the art, it still may be used
Modified with to the technical scheme described in foregoing embodiments, or equivalent is carried out to which part technical characteristic.
