Abstract
The present invention discloses a kind of automatic preprocess method of the setting parameter for relay protection fixed value setting, comprises the following steps：(1) read fixed value adjusting and calculate the power system operating mode for needing to use；(2) the power network primary equipment for needing to carry out fixed value adjusting calculating is read；(3) read relay protection fixed value setting and calculate used setting principle；(4) according to the setting principle read, it is determined that the setting parameter type calculated required for every setting principle；(5) merger power network primary equipment and setting parameter type, eliminate the equipment and setting parameter type repeated；(6) the power network primary equipment information and setting parameter type information after merger are sent to computing module and carries out setting parameter calculating；(7) the related setting parameter for reading the power network primary equipment that computing module is provided combines the setting principle completion relay protection fixed value setting work read.Present invention, avoiding calculating that is invalid and repeating, amount of calculation is greatly reduced, calculating speed is improved.
Description
Technical field
The invention belongs to the method for the relay protection of power system fixed value adjusting of field of relay protection in power, especially relate to
And the implementation method calculated to relay protection fixed value setting.
Background technology
The adaptive setting work of relay protection constant value is one of center of gravity of relay protection specialty.Existing relay protection constant value
Adjust workflow as follows：
User first has to the operation of power networks for confirming to need to consider in adaptive setting software before fixed value adjusting work starts
Mode, confirm need carry out fixed value adjusting equipment, then user manually boot adaptive setting software " setting parameter is located in advance
Reason " task, completes the setting parameter preparation before fixed value adjusting is calculated, and adjust ginseng by ready by adaptive setting software
Number is saved.Adaptive setting software is completed after " setting parameter pretreatment " work, and user needs to select calculative definite value
And the related setting principle that fixed value adjusting is used, manually boot adaptive setting task again afterwards.Adjust software receive it is whole
Devise a stratagem is calculated after task order, the setting parameter being stored in before being read from database by " setting parameter pretreatment " task, and root
The setting principle selected according to user, which is further calculated, to be obtained protecting definite value.
The problem of above-mentioned fixed value adjusting computation schema has following：
1st, " setting parameter pretreatment " calculates needs and manually started, if lacking the step, and follow-up adaptive setting can be because
Be cannot needed for setting parameter without result；
2nd, after the completion of " setting parameter pretreatment " calculating, the model (example of power network has been readjusted in the event of user
Such as circuit, the parameter of transformer), the mode (throwing of circuit stops state, the ground state of transformer) of system, it is existing " to adjust
Parameter is pre-processed " module can't automatic sensing be to above-mentioned change and carries out the Adjustable calculation of setting parameter, except it is unartificial again
Start " setting parameter pretreatment ".It is not stranghtforward due to adjusting work, user is after " setting parameter pretreatment " is completed
The situation for carrying out electric network model or system mode adjustment happens occasionally, therefore often obtains unexpected result of calculation.
3rd, " the setting parameter pretreatment " manually started calculates the mode information selected only in accordance with user and facility information enters
Row setting parameter preparation, the setting principle selected not according to user is optimized, therefore the part in its result of calculation
Data are likely to take less than at all in follow-up tuning process, and this can form substantial amounts of invalid computation result, cause calculating
Amount, the waste for calculating time and memory space.Such as user is when calculating route protection definite value, if only consideration and subordinate's line
The cooperation on road, then it is all nothing that cooperation and the setting parameter related with the anti-cooperation of higher level's circuit to subordinate transformer, which are calculated,
Effect.
The content of the invention
The technical problems to be solved by the invention, are that the defect and deficiency being directed in aforementioned background art are used there is provided one kind
In the automatic preprocess method of the setting parameter of relay protection fixed value setting.Its object is to provide a kind of more high efficiency, it is convenient
Adaptive setting processing scheme.
The technical scheme that the present invention takes is：A kind of setting parameter for relay protection fixed value setting side of pretreatment automatically
Method, the method includes the steps of：
(1) read fixed value adjusting and calculate the power system operating mode for needing to use；
(2) the power network primary equipment for needing to carry out fixed value adjusting calculating is read；
(3) read relay protection fixed value setting and calculate used setting principle；
(4) according to the setting principle read, it is determined that the setting parameter type calculated required for every setting principle；(5)
Merger power network primary equipment and setting parameter type, eliminate the equipment and setting parameter type repeated；
(6) the power network primary equipment information and setting parameter type information after merger is sent to computing module to be adjusted
Parameter is calculated；
(7) setting principle that the related setting parameter combination for the power network primary equipment that reading computing module is provided is read is complete
Into relay protection fixed value setting work.
Step (4), (5), (6) and (7) is realized by adaptive setting program in methods described, is carried out without user dry by hand
In advance.
There is following spy using the automatic preprocess method of the setting parameter of the relay protection fixed value setting based on this programme
Point：
1 user need not manually start " setting parameter pretreatment ", the step of simplifying adaptive setting and process；
2 calculated using newest model, mode data automatically, it is to avoid calculating parameter is not more after related data is adjusted
The calculating mistake newly caused；
3 carry out merger processing automatically according to adjust equipment, setting principle that user sets to computing device and calculating type,
Calculating that is invalid and repeating is avoided, amount of calculation is greatly reduced, improves calculating speed.
Brief description of the drawings
Fig. 1 is flow chart of the method for the present invention；
Embodiment
Below with reference to accompanying drawing 1, technical scheme is described in detail.
The method includes the steps of：
(1) read fixed value adjusting and calculate the power system operating mode for needing to use；
(2) the power network primary equipment for needing to carry out fixed value adjusting calculating is read；
(3) read relay protection fixed value setting and calculate used setting principle；
(4) according to the setting principle read, it is determined that the setting parameter type calculated required for every setting principle；
(5) merger power network primary equipment and setting parameter type, eliminate the equipment and setting parameter type repeated；
(6) the power network primary equipment information and setting parameter type information after merger is sent to computing module to be adjusted
Parameter is calculated；
(7) setting principle that the related setting parameter combination for the power network primary equipment that reading computing module is provided is read is complete
