Recover.
If 3) Intelligent terminal of distribution network STU4 communicates abnormal with STU3, Intelligent terminal of distribution network STU4 will actively and next
Adjacent terminal, i.e., communicate with Intelligent terminal of distribution network STU2, judges trouble point in switch Q41 and switch by fault current information
Between Q22, Intelligent terminal of distribution network STU4 and STU2 controlling switch Q41 and Q22 tripping operation isolated fault are opened after Fault Isolation success
Close QF2 to close a floodgate, when Intelligent terminal of distribution network STU3 judges to meet contact combined floodgate condition, control interconnection switch Q31 closes a floodgate, and completes to supply
Electricity recovers.
If 4) communicate abnormal between Intelligent terminal of distribution network STUB, STU4, STU3, STU2, logic is exited.
The fault-tolerant processing of j, element fault
1) it is due to self reason miss operation when on-load switch tripping, i.e. the on-load switch action.If basic routing line
On distribution terminal occur this kind of failure when, after the tripping of its own detectable on-load switch, immediately to phase on its main line
Adjacent distribution terminal sends open command, realizes that the equipment such as the isolation of failure, subsequent contacts switch continue relevant action with this, real
The maximum power supply of existing non-faulting section.Example：If failure a, switch Q11 trippings because the communication between terminal is not interrupted, then by
The principle of distributed proccessing understands must have switch QF1 to be each turned off with switch Q11, is as a result but that switch QF1 disconnects, switch
Q11 is still closed in the case of detecting and itself not disconnecting, and switch Q11 sends and sends control command to switch Q12, makes switch
Q12 disconnects, and failure is removed, and now failure is removed, and then switchs Q31 and proceeds relevant action：Load anticipation.If not therefore
Barrier section load nonoverload, then interconnection switch action, is failure to actuate if overload, and distributed treatment action is reasonable.If failure b, opens
Q12 trippings are closed, now the action command of terminal is：Switch QF1, switch Q12 and switch Q21 disconnections, detected certainly because switching Q12
Body is not moved, then send open command to adjacent basic routing line switch：Switch Q11 disconnects, and then fault section is isolated.Switch
QF1 is closed, and switch Q31 carries out load anticipation to upstream non-faulting section, if not faulty section load nonoverload, then interconnection switch is dynamic
Make, be failure to actuate if overload, distributed treatment action is reasonable；
If failure on branched line, then the terminal will be opened to the load on two basic routing lines adjacent thereto of its upstream
Pass sends open command, realizes that the equipment such as the isolation of fault section, subsequent contacts switch continue relevant action with this, realizes non-event
The maximum power supply of barrier section.Example：If failure h, Q23 trippings are switched, end command now is switch QF1, and switch Q23 breaks
Open, because switch Q23 detect itself tripping, then its upstream main line way switch Q21 and switch Q22 send open command, realize
The isolation of failure, interconnection switch Q31 carries out load anticipation and determines whether closure, and switch QF1 closures realize the confession of non-faulting section
Electricity.During on-load switch tripping, the flow chart of Fault Isolation is realized as indicated with 2.
2) malfunction is switched, if the two of certain distribution terminal adjacent on-load switch remote control separating brake line reversal on circuit.Match somebody with somebody when one
After the adjacent on-load switch of electric terminals two is defined as malfunction, distribution terminal carries out self-correcting：Two related loads are opened
Put row command operation anti-again into.If example failure b, on-load switch Q21 and switch Q22 reversal connections, control command are broken for switch QF1
Open, switch Q12 disconnects with Q21 is switched, when STU2 detects switch Q21 to disconnect, and after switching Q22 disconnections, be judged to herein
Two on-load switch malfunctions, i.e., send anti-command operation to it, realizes the isolation of failure, and it is true that interconnection switch Q31 carries out load anticipation
Whether fixed to close, switch QF1 closures realize the power supply of non-faulting section.During on-load switch malfunction, the flow of Fault Isolation is realized
Figure is as indicated at 3.
