Description
Technical field
The present invention relates to field of mobile communication, be specifically related to a kind of intelligent distribution network fault partition method.
Background technology
Along with the increase of global energy, in order to alleviate energy shortage, on the basis of power distribution network, access distributed electrical source apparatus,
To some extent solve powerup issue, but how the faults itself that intelligent network distribution produces is quickly isolated, ensure
The normal power supply in non-faulting district, becomes critical and studies a question.
Traditional power distribution network protective relaying device dispersion is installed, and sequential phase interworking is passed through in the overcurrent protection of each protection device
Closing, transformer station 10KV exit fast tripping protection is due to the cooperation requirement with higher level's guard time, and general setting time is shorter.Although
Optical-fiber longitudinal difference, protection based on synchronous sampling technique can solve the selectivity of protection, but require high to communication speed, become
This is higher, is not suitable for promoting.
Based on this, study and develop a kind of intelligent distribution network fault partition method of design.
Summary of the invention
The technical problem to be solved is: the purpose of technical solution of the present invention is: provide a kind of intelligent network distribution
Failure separation method.
The present invention is achieved through the following technical solutions:
A kind of intelligent distribution network fault partition method, including following operating procedure:
Step (1): fill configuration file under each distribution terminal, configuration file includes the address of distribution terminal and positive negative side
Corresponding relation between active flag table, the locking contingency table of both forward and reverse directions overcurrent protection；
Step (2): distribution terminal installed stream starting element, direction sends positive and negative to distribution terminal after crossing stream starting element action
Stream starting state is crossed in direction；
Step (3): the positive and negative direction that parsed stream distribution terminal transmits crosses stream starting state, and is filled up to according to corresponding relation
In corresponding positive and negative direction active flag table；
Step (4): after stream startup is crossed in distribution terminal direction, at the appointed time, lock contingency table according to both forward and reverse directions overcurrent protection
In the start bit of locking tag lookup both forward and reverse directions active flag table, determine direction after comprehensive all starting states that need to associate
Overcurrent protection whether action.
Wherein, described step (1) is specially on intelligent network distribution circuit needs the distribution by time cooperation region
Terminal carries out unifying configuration, arranges its correspondence position in both forward and reverse directions active flag table according to address difference, square
To separate with reciprocal active flag table.
The present invention compared with prior art, has such advantages as and beneficial effect:
Technical scheme of the present invention can realize location quick to intelligent distribution network fault and isolation, and fault impact is isolated in minimum
Scope, reduces the damaged condition of fault element, shortens the low-voltage time of load, it is ensured that the non-faulting region in intelligent network distribution
Normal power supply, and will be when intelligent network distribution breaks down, it is possible to quickly fault zone is isolated, it is ensured that distribution and distribution are eventually
The safe operation of end, thus improve the power supply capacity of distribution.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment, the present invention is made
Further describing in detail, the exemplary embodiment of the present invention and explanation thereof are only used for explaining the present invention, are not intended as this
The restriction of invention.
Embodiment 1:
A kind of intelligent distribution network fault partition method, including following operational approach:

Step (2): distribution terminal installed stream starting element, direction sends positive and negative to distribution terminal after crossing stream starting element action
Stream starting state is crossed in direction；
Step (3): the positive and negative direction that parsed stream distribution terminal transmits crosses stream starting state, and is filled up to according to corresponding relation
In corresponding positive and negative direction active flag table；
Step (4): after stream startup is crossed in distribution terminal direction, at the appointed time, lock contingency table according to both forward and reverse directions overcurrent protection
In the start bit of locking tag lookup both forward and reverse directions active flag table, determine direction after comprehensive all starting states that need to associate
Overcurrent protection whether action.
Described step (1) concrete operations are to the distribution needed on intelligent network distribution circuit by time cooperation region
Terminal carries out unifying configuration, arranges its correspondence position in both forward and reverse directions active flag table according to address difference, square
To separate with reciprocal active flag table
The present embodiment can realize location quick to intelligent distribution network fault and isolation, fault impact is isolated in minimum zone, reduces
The damaged condition of fault element, shortens the low-voltage time of load, it is ensured that the normal power supply in the non-faulting region in intelligent network distribution,
And will be when intelligent network distribution breaks down, it is possible to quickly fault zone is isolated, it is ensured that distribution and the safety of distribution terminal
Run, thus improve the power supply capacity of distribution.
Above-described detailed description of the invention, has been carried out the purpose of the present invention, technical scheme and beneficial effect further
Describe in detail, be it should be understood that the detailed description of the invention that the foregoing is only the present invention, be not intended to limit the present invention
Protection domain, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. done, all should comprise
Within protection scope of the present invention.
