The data integration method provided by the invention imports a database used by province dispatch setting calculation to a network dispatching database, realizes the distribution and maintenance of the setting calculation data, and centralized sharing, and effectively reduces the workload of data interaction.
Description
Technical field
The invention belongs to the relay protection of power system technical field, be specifically related to the data integration method that a kind of relay protection setting calculates.
Background technology
Correctly carrying out of relay protection setting evaluation work is the important foundation sex work of guaranteeing power network safety operation; Obtaining very big progress aspect the robotization of large-scale power grid relay protection setting evaluation work in recent years; But the method for system equivalent is still adopted in regional power grid scheduling at present neutral (being called for short net transfers) and net province dispatching center (be called for short to economize and transfer) relay protection setting calculating parameter exchange, and promptly net is in harmonious proportion to economize to transfer respectively and exchanges the multiple spot equivalent parameters that we transfer the scope tube electrical network to the other side.
Yet; Along with the continuous expansion of scale of power, according to the pattern of present uniform dispatching, differentiated control, net is economized to transfer and the separation on the scope tube more and more; It is more and more to exchange the required data such as grid equipment parameter, equivalent impedance and cooperation definite value of the calculating of adjusting between net is economized and transferred; Continue to adopt the drawback of traditional equivalent parameters switching method more and more obvious: on the one hand, along with the fast development of power grid construction, the contact that net is economized between transferring is tight further; The system equivalent separation is also in continuous adjustment, and the typing of equivalent calculating and equivalent parameters etc. becomes and becomes increasingly complex.On the other hand; The equivalent parameters of annual exchange all was according to current or next year system's maximum operational mode and minimum operational mode calculate between net economize to be transferred; Thereby make that equivalent parameters is difficult to mate fully with real system ruuning situation; Especially be difficult to contain some extreme methods of operation, these errors result of calculation that possibly cause adjusting can't be considered the most extreme method of operation, causes protecting the hidden danger of malfunction or tripping.
Summary of the invention
In view of this; The data integration method that the object of the present invention is to provide a kind of relay protection setting to calculate; In the existing calculation automation system of adjusting, increase data integration function, import to the database of economizing adjustment devise a stratagem calculation use in the net adjusting data storehouse, the computational data of having realized adjusting distributes and safeguards; Concentrate and share, and can reduce the workload of data interaction effectively.
The present invention realizes through following technical scheme:
The data integration method that a kind of relay protection setting calculates may further comprise the steps: judge whether the derivation mode that provincial power network is selected is complete derivation, if the derivation mode of selecting is complete derivation; Then select the graph topology parameter and the primary parameter of provincial power network, judge whether the ExportRange that provincial power network is selected is whole derivation, if the ExportRange of selecting is whole derivation; Then select the whole factories station and the circuit of provincial power network, derivation mode and the ExportRange selected are exported as the XML formatted file, the XML formatted file is transferred to net office dispatching center; Selection needs the file of importing from the XML formatted file, judges whether the XML formatted file of selecting need mate importing, if the XML formatted file of selecting need mate importing; Two steps operation below then all factory that need mate stations being carried out:; Judge whether the factory station all is present in the file and target area of needs importing, if the factory station all is present in the file and target area of needs importing, graph topology parameter that factory stands in the graph topology parameter at factory station and primary parameter and the target area in the file that then will import and primary parameter coupling; Judging whether all factory station travels through finishes; If all factories station all traversal finishes, the circuit of then selecting article one to mate judges whether circuit all is present in the file and target area of needs importing; If circuit all is present in the file and target area of needs importing; The parameter matching of circuit in the parameter of circuit and the target area in the file that then will import is judged whether all circuits that need mate travel through to finish, if all circuits all travel through and finish; Then to all two steps operations below the operating modes for performing:; Judge whether the method for operation is arranged in the target area, if in the target area method of operation is arranged, the method for operation in the file that then will import and the coupling of the method for operation in the target area; Judging whether all methods of operation travel through finishes; If all methods of operation all travel through and finish, the electric pressure of the file that then will import and the electric pressure of target area coupling import to the target area with the file that disposes.
Method of the present invention is further comprising the steps of: if the derivation mode of selecting is not complete derivation, then select the primary parameter of provincial power network.
Method of the present invention is further comprising the steps of: if the ExportRange of selecting is not complete derivation, then select the part factory station and the circuit of provincial power network.
Method of the present invention is further comprising the steps of: if the XML formatted file of selecting need not mate importing, and the step that the electric pressure of then returning the file that needs are imported and the electric pressure of target area are mated.
Method of the present invention is further comprising the steps of: if the factory station is not all to be present in the file and target area of needs importing, then judging whether needs to keep the factory station, if then keep the factory station, then deletes factory if not and stands.
Method of the present invention is further comprising the steps of: standing to travel through as if all factories does not finish, and then jumps to next factory station, and returns and judge whether the factory station all is present in the file of needs importing and the step in the target area.
Method of the present invention is further comprising the steps of: if circuit is not all to be present in the file and target area of needs importings, need then to judge whether reserved line, if reserved line is then then deleted circuit if not.
Method of the present invention is further comprising the steps of: if all circuits do not travel through and finish, then jump to next bar circuit, and return and judge whether circuit all is present in the file of needs importing and the step in the target area.
Method of the present invention is further comprising the steps of: if do not have the method for operation in the target area, then add the method for operation to target area.
Method of the present invention is further comprising the steps of: if all methods of operation do not travel through and finish, then jump to the next method of operation, and return and judge the step whether method of operation is arranged in the target area.
The invention has the advantages that: the distribution of the computational data of having realized adjusting is safeguarded, concentrates and shares, and has reduced the mutual workload of the computational data of adjusting; Make dispatching centers at different levels all can grasp more comprehensive electrical network parameter, protection configuring condition, the cooperation between conveniently protecting is checked.
