Abstract
The invention relates to a complementary method for handling a fault in a power distribution network based on a power guarantee mode. An analysis is conducted for a power guarantee mode to obtain a solving strategy for differential fault handling. The power guarantee mode is to ensure, for dual power supply users, the differential fault handling of the dual power supply property of the users after non-fault recovery, and is mainly to ensure the dual power supply property of the dual power supply users, that is, before fault recovery, the dual power supply users are calculated dynamically, and the priority level of recovery schemes is modified by comparing power supplies of the dual power supply users with newly transferred power supplies. The invention considers the adaptability of fault handling functions of the power distribution network at this stage, the impact of the trend for special operating modes on a general fault handling logic algorithm, and the general fault handling logic flaws, and ensures wide adaptability and practicability of fault handling for the power distribution network, thereby improving the fault handling reliability of the power distribution network, shortening the power supply time and providing customer satisfaction.
Description
Technical field
The present invention relates to a kind of distribution network failure treatment technology, relate to the troubleshooting technology in electrical power distribution automatization system, specifically
It is a kind of based on protecting power mode distribution network failure process compensation process.
Background technology
Distribution network failure of the prior art isolation and service restoration method, be both for general distribution network shelf structure and be analyzed
's.But, owing to power distribution network powering mode is various, under the method for operation for guarantor's power mode, existing distribution network failure processes
Cannot meet actual demand, protect power mode be dual power supply user ensure non-faulting recover after the pattern of dual power supply of user, therefore
It is required for the special method of operation and the distribution network failure treatment technology of differentiation is provided, power with the satisfied power distribution network being continually changing
The demand of pattern.
Summary of the invention
For solving the deficiencies in the prior art, it is an object of the invention to by the distribution network failure under several special methods of operation is entered
Row is analyzed, thus the method having been resolved the troubleshooting under this special method of operation, and supplement skill by differentiation troubleshooting
Art, is incorporated distribution network failure and is processed in functional module, met the demand of present stage distribution network failure disposal ability.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that:
The positive effect of the present invention and advantage be:
A kind of based on protecting power mode distribution network failure process compensation process, it is analyzed for protecting power mode, obtains differentiation fault
Process resolution policy, protect power mode be for dual power supply user ensure non-faulting recover after user dual power supply differentiation therefore
Barrier processes the dual power supply being to ensure that dual power supply user, i.e. before fault recovery, dynamic calculation dual power supply user, and by double electricity
The power supply of source user and newly turn the power supply of confession and contrast, thus revise the priority level of recovery scheme.
The positive effect of the present invention and advantage be:
The present invention not only allows for present stage distribution network failure and processes the adaptability of function, it is also contemplated that for the special method of operation
Trend processes the impact that logical algorithm produces to ordinary failures, and ordinary failures processes the defect of logic, it is ensured that power distribution network event
The extensive adaptability of barrier process and practicality, thus improve distribution network failure and process reliability, shorten power-on time, it is provided that use
Family satisfaction.
Accompanying drawing explanation
Fig. 1 is that after dual power supply user ensures non-faulting recovery, the FA of the dual power supply of user tests looped network figure；
Fig. 2 is troubleshooting process figure.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention made concrete introduction.
A kind of based on protecting power mode distribution network failure process compensation process, it is analyzed for protecting power mode, obtains differentiation fault
Process resolution policy, protect power mode be for dual power supply user ensure non-faulting recover after user dual power supply differentiation therefore
Barrier processes the dual power supply being to ensure that dual power supply user, i.e. before fault recovery, dynamic calculation dual power supply user, and by double electricity
The power supply of source user and newly turn the power supply of confession and contrast, thus revise the priority level of recovery scheme.
Such as accompanying drawing 1, #1 line, #2 line and #3 line are three contact situations, and #1 ring main unit is powered by #1 line, #2 ring main unit and #3
Ring main unit is powered by #3 line, and #4 ring main unit is powered by #2 line, and the contact point of #1 line and #3 line is #1 ring main unit 12 interconnection switch,
The contact point of #2 line and #3 line is #4 ring main unit 42 interconnection switch, and responsible consumer is dual power supply user, and two ends power supply is respectively #1
Line and #3 line, two end switch are respectively #1 ring main unit 13 switch and #2 ring main unit 23 switchs.
Such as accompanying drawing 1, between #2 ring main unit and #3 ring main unit, cable breaks down, and the isolation scheme that system is given is for disconnecting #2
Ring main unit 24 switch and #3 ring main unit 31 switch, and upstream recovery scheme is the 3# wiretap that closes, and downstream recovery scheme has 2 kinds of feelings
Condition, one is #1 ring main unit 12 interconnection switch that closes, and two is #4 ring main unit 42 interconnection switch that closes.Two kinds of recovery schemes are the most former
It is then excellent for load factor the lowest.
And it practice, the load factor working as the 2 kinds of recovery schemes in downstream all (is defaulted as 90%) in threshold values, preferably close #4 looped network
Cabinet 42 interconnection switch, it is ensured that responsible consumer is still by multiple feed, if selecting to close #1 ring main unit 12 interconnection switch, when
1# wiretap trips, and responsible consumer will dead electricity.
After ensureing non-faulting recovery for dual power supply user, the differentiation troubleshooting of the dual power supply of user focuses on guarantee pair
The dual power supply of power user, i.e. before fault recovery, dynamic calculation dual power supply user, and by the power supply electricity of dual power supply user
Source and newly turn the power supply of confession and contrast, thus revise the priority level of recovery scheme.
The handling process protecting the supplementary technology of power mode distribution network failure process of the present invention is as follows:
Fault location；
Troubleshooting strategy generating；
Differentiation troubleshooting correction；
Scheme optimization generates；
Scheme performs；
Troubleshooting software module operational flow diagram sees accompanying drawing 2.
The ultimate principle of the present invention, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry,
Above-described embodiment limits the present invention the most in any form, the technical scheme that the mode of all employing equivalents or equivalent transformation is obtained,
All fall within protection scope of the present invention.
