Power distribution automation main station system failure processing test active interference type and Scenario-Based Design
In order to ensure the diversity of test cases, typical fault scene should consider that position, short trouble type occur for failure
With test scene etc..Test scene includes switch fault, communication failure, extension wire failure etc..Meanwhile
Various faults or several scenes can be allowed in individual test case while occurred, ensure that test cases diversity and
Autgmentability.Fault scenes set include setting initial separating brake (i.e. setting interconnection switch position), short trouble type and position,
Responsive state, Communication Jamming etc. are switched, the fault scenes of required test can be entered according to the inductive design of fault scenes
Row is set.In view of it is existing concentration main station type, distribution and on the spot control etc. a variety of electrical power distribution automatization system construction scales
And configuration mode.
In order to increase the comprehensive and depth of test examination, increase active interference factor, typical fault scenes should consider
Position that failure occurs, short trouble type, active interference mode, service condition etc..The design of fault scenes is thought
Road is as follows：
(1) abort situation selects：Backbone；Branched line；
(2) fault type selects：Earth fault (single-phase, two-phase, three-phase)；Two-phase phase fault；
(3) active interference factor：Switch whether tripping；Switch whether malfunction；Switch the response that whether is delayed；Locking；It is logical
Whether letter interrupts；
(4) service condition is set：Whether open loop operation；Whether turn for allowance deficiency；With the presence or absence of maintenance circuit；It is standby
Line fault；
(5) multiple failure triggers：Break down different location；Multiple failure scene occurs simultaneously.
By taking the monocyclic cable system in C class power supply areas as an example, the test to several fault scenes is illustrated.According to
The section of test required for electrical power distribution automatization system, with reference to load density, user's significance level, electricity consumption level, GDP etc.
Factor, power supply area where determining itself, selects to test the typical distribution net wiring construction of such power supply area.
It is assumed that it is C class power supply areas that surveyed electrical power distribution automatization system, which implements region, wiring construction is cable system, therefore according to table 5-1,
It is test object to select Single-ring network.
Monocyclic cable system model is established, after distribution network model is built up, next stage is designed and tested for fault scenes

Situation discussion), short trouble and the simultaneous twin failure scene of tripping.Wherein, on-load switch 1, on-load switch 2,
On-load switch 3 and on-load switch 4 pass through digital communication by physical simulation, outlet breaker and other on-load switches
Emulation.
(1) the short trouble scene in the case of enough for allowance is turned
Failure occurs between on-load switch 1 and 2, and outlet breaker trips first, and system enters fault isolation stage.
Switch 1 trips respectively with switch 2, there is the switch of disconnection on trouble point to the path between the transformer station of both ends.In failure
Restoration stage, interconnection switch close a floodgate, and outlet breaker closes a floodgate, and have opening for disconnection on the path of interconnection switch 5 to trouble point
2 are closed, the switch 1 for having disconnection on the path of outlet breaker first to trouble point.Therefore, Fault Isolation and failure are considered
Recover two stages, this troubleshooting is successful.

Therefore identical with previous case in the processing procedure of fault isolation stage, i.e. fault isolation stage processing is successful.
In the fault recovery stage, due to turning to fail to close a floodgate for allowance deficiency, interconnection switch, only outlet breaker re-closes, and goes out
Mouthful breaker first is to the switch 1 for having disconnection on the path of trouble point, therefore the fault recovery stage is also safe and reliable, whole failure
Processing procedure is safe and reasonable.
(3) short circuit and switch failure twin failure scene
Under normal operating condition, on-load switch 4 has been set to tripping state.Failure occurs between switch 3 and 4,
Switch 3 successfully be detected fault message and trip, but switch 4 due to there is provided tripping, so it keeps "on" position not
Action, adjacent interconnection switch 5 is not because switch 4 disconnects normally and keeps gate-dividing state constant, trouble point to both ends
There are the switch 3 and switch 5 of disconnection on path between transformer station's power supply.In the fault recovery stage, outlet breaker closes a floodgate,
To the switch 3 that disconnects on the path of trouble point be present in outlet breaker first, therefore, fault recovery stage also safe and reasonable.
Finally it should be noted that：The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof, although
