Multiple process；
Simulation operations module provides the various normal operations of emulation, attended operation, the various feeder line excessively streams of emulation manufacture, failure
Deng；
Simulation communication module realizes communication protocol and heartbeat of the emulation host computer with each feed connection node distribution terminal.
As shown in Fig. 2 when the line feed terminals of distribution have been installed in place, network has been connected normally, and powers up operation
Afterwards, emulation host computer machine is connected on the net, it is possible to realize simulation process.
1st, the selection emulation feeder line topology corresponding with actual physics feeder line topology；
2nd, startup emulation command is sent, checks that each distribution terminal enters simulation status
3rd, normal operation emulation is checked, check each distribution terminal emulation gathered data whether the number occurred with simulation software
According to consistent
4th, different feeder line excessively streams and operation troubles are manufactured, the action checked on emulation host computer and failure logging SOE
5th, after the completion of each fault logic, simulated failure maintenance recovers feeder line and normally run.
When finding that FA logics are wrong in the 6th, emulating, the logic of distribution terminal is changed.Repeat simulation process.
7th, after emulation terminates, emulation is exited, distribution terminal is returned to normal operation mode.
The present invention deploys emulation component in every station power distribution terminal node to be used to emulate data acquisition and the control of switch,
When the distribution terminal power-up on certain feeder line, and after connecting to network, access emulation host computer, chooses from anywhere in network
After the physical topology mode of the feeder line, it is possible to notify that all distribution terminals enter simulation status on feeder line.Emulate host computer just
The operation power parameter there is provided each node, on off state etc. are run as actual feeder line physical topology, these operations are joined

Block.
When the automation distributed logic of distribution terminal receives these fault alarm signals and operating state, begin to and imitate
True host computer is interacted, so as to truly realize the core of " fault location-Fault Isolation and the fault recovery " of distribution feeder
The heart automates logic.This is just able to verify that the correctness for each distribution terminal logic being distributed on this feeder line, after the completion of checking
The shielding of every station power distribution terminal node copying is then restored to actual running status.
In Fig. 2, a marks of the CDINP in global variable, decision is to enter emulation to be also up, in emulation
In the case of, state value report DIDB is obtained in global variable；
A marks of the CDOUT in global variable, decision is to enter emulation to be also up, in simulation scenarios
Under, the output control state value into global variable reports CDINP and emulation MMI；
Mark, is constantly updated (such as 10 seconds) by MMI, removes (such as 60s) when DTU emulation modules are grasped, FA and emulation
Module is same source code program, shares global variable and FA initialization, and emulation module is communicated with emulation MMI by UDP modes.
It is the program run on PC to emulate MMI, and after emulation mark is set, all power supply and power distribution station DTU are
Into simulation status, normal condition is then all recovered after removing emulation mark.
Before failure of setting out again, ISWiSTS can be set, ISWiFTL, OSWiFTL state does not can be set in OSWiSTS states,
When producing a failure, GEa/bFLT and ISWiFTL, OSWiFTL can be set to emulate a short circuit grounding failure, hereafter
MMI can not be provided with, can only read states, but except that, DTU institute it is stateful be 0, and emulate MMI provide one just
The normal feeder line method of operation：CBaSTS, CBbSTS, ISW1STS, ISW2STS, OSWiSTS are 1 and some ISW1/2STS=
0, all xxxxFTL abnormality alarmings, LOCKa/b is 0.The method of operation can manually be set in non-faulting.
