Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
The present invention proposes a kind of layer-management method of the multistage electrical network refined model based on the variable quantity pattern, according to three different phases in the electric network model reciprocal processes at different levels, adopt three kinds of corresponding distinct methods to guarantee the high efficiency of the accuracy of electric network model and model generation, maintenance and application process, as shown in Figure 1.For making purpose of the present invention, method, technical scheme and advantage clearer and more definite, regulate and control the center, economize and transfer three grades of scheduling models as example take state's accent, the subregion of actual electric network below in conjunction with accompanying drawing, the method for the invention is described in further details.
The present invention transfers three grades of dispatching of power netwoks models as example take state's accent, subregion regulation and control center, province; in conjunction with the integrated business demand of adjusting the computational data platform of the whole network relay protection; the specific implementation process of each method of the present invention is described; described integrated adjusting calculated the calculating of adjusting that refers to based on the whole network refined model in the present invention; in the process of calculating of adjusting, the Value Data such as do not adopt.The integrated computational data platform of adjusting of the whole network relay protection is responsible for the management of the whole network relay protection professional equipment and the computational data of adjusting; generate the refined model of the whole network relay protection specialty relevant device and network topology structure in this data platform, the personnel of threads protection specialties at different levels use this whole network refined model and carry out the calculating of adjusting based on the whole network refined model.
In the initial relay protection specialty electric network model of scheduling at different levels; each provincial thread, subregion regulation and control center and state transfer safeguard respectively own scheduling extent of competence interior with the electric network model relay protection specialty; adopt equivalent method to process to other electrical networks that are attached thereto; this will certainly affect the precision that relay protection setting calculates; so be necessary to generate the whole network refined model; for calculating, relay protection setting provides more meticulous model; improve the precision of adjusting and calculating, satisfy the under the new situation computation requirement of adjusting of interconnected network.
Among this embodiment, state transfers, subregion is regulated and control the center, economize three grades of dispatching of power netwoks models of accent as shown in Figure 2.The generative process of the whole network refined model comprises two parts, a part is the process that is generated longitudinally higher level's electric network model by subordinate's dispatching of power netwoks model splicing, and this process refers to dispatch electric network model and a plurality of process that the complete higher level who comprises subordinate's dispatching of power netwoks model dispatches the whole network model of subordinate's dispatching of power netwoks model splicing generation based on the IEC61970CIM model by a higher level based on the IEC61970CIM model; Another part refers to that horizontal grid model splicing a plurality of at the same level forms the process of the whole network refined model.Generate in the process of the whole network refined model at the electric network model of adjusting a wage scale based on province's accent electric network model, subregion regulation and control center electric network model, state, subregion is regulated and control the center under at first by provinces at different levels accent the relay protection specialty electric network model in its scheduling extent of competence being uploaded to it, be responsible for the electric network model of each provincial scheduling resolves by the integrated computational data platform of adjusting of relay protection of subregion regulation and control centre grade, and resolve one's duty and regulate and control the interior electric network model of central dispatching extent of competence, these models are spliced, form the electrical network refined model in this subregion regulation and control center range; Finish based on behind the electrical network refined model in this subregion regulation and control center range based on said process at each subregion regulation and control center; being uploaded to state transfers in the integrated computational data platform of adjusting of relay protection; state transfers and is responsible for resolving the electrical network refined model that upload at each subregion regulation and control center; and the electric network model in the parsing state key degree extent of competence; these models are spliced; form the electrical network refined model of relay protection specialty in the network-wide basis, for the integrated computing application of adjusting of thread relay protection specialty at different levels.
In the generative process of above-mentioned the whole network refined model, the parsing of model and splicing and method are followed following method:
Belong to the device models in the different scheduling extents of competence in vertical model analyzing process in to same station, the device parameter that the thread of different stage provides may be inconsistent, adopts which parameter just to become one of key factor that guarantees model accuracy; In horizontal model splicing process, processing to interconnection is one of key issue, the parameter information of the described interconnection of electrical network in different zones may be inconsistent, and the parameter accuracy that how to guarantee interconnection also is the key point that guarantees the whole network model accuracy.According to grid equipment " source is safeguarded; the overall situation is shared " principle, namely whose scheduling, the principle of whose maintenance, the present invention all is as the criterion with the model data that scheduling institution under this equipment provides to all grid equipment models in order to guarantee the accuracy of electric network model, for the equipment that belongs to different scheduling extents of competence in the same transformer station, according to the division of scheduling authority, the model data that adopts respectively the different stage thread to provide is ignored the data that are not that affiliated extent of competence provides.For the interconnection between each zone, usually dispatch authority at the upper level thread, the electric network model that adopts the upper level dispatching office to provide neglects the model data that subordinate's thread provides.
According to dispatching of power netwoks mechanism rank order from low to high, the electric network model file is successively uploaded, successively resolve splicing, finally form the whole network refined model, its procedure chart is as shown in Figure 3.
Concrete, after next stage (as economize transferring) electric network model File Upload is to upper level (such as subregion regulation and control center) the integrated computational data platform of adjusting of relay protection, realize the longitudinal spliced of electric network model, in longitudinal spliced process, at first resolve the electric network model of economizing the scheduling authority of adjusting a wage scale, in resolving, only resolve the device model of economizing in the scheduling authority compass of competency of adjusting a wage scale, for the device model in the subregion regulation and control centre grade scheduling authority compass of competency, ignore and will not resolve, but the parsing of the topological relation between reservation and the subregion regulation and control centre grade scheduling extent of competence equipment; Having resolved province adjusts a wage scale behind the electric network model file that scheduling institution provides, resolve again the electric network model file that subregion regulation and control centre grade scheduling institution provides, equally, in the process of resolving, only resolve the device model in the subregion regulation and control centre grade scheduling authority compass of competency, for the adjust a wage scale equipment of scheduling authority compass of competency of province, because in the electric network model that scheduling provides is adjusted a wage scale by province, be parsed, need not to finish at subregion regulation and control centre grade; Equipment for subregion regulation and control centre grade higher level scheduling (state's accents) authority compass of competency need not to resolve, and waits until subregion and regulates and control the resolving that the center higher level dispatches electric network model and finish; For province adjust a wage scale or subregion regulation and control centre grade scheduling institution electric network model between interconnection because its scheduling authority also need not to resolve in separately upper level scheduling, wait until the resolving that higher level separately dispatches electric network model and finish; By that analogy, the grid model splicing process that each subregion regulation and control center to state transfers is also followed said process, forms the whole network refined model.
By the application of above-described embodiment, proved that the present invention can reach assurance electric network model accuracy, improves the purpose of model analyzing speed and efficient.
After the integrated computing platform of adjusting of relay protection generates the whole network refined model, in database, generate the basic version of each device model.To the maintenance phase of the whole network model, the maintenance of relay protection device model in the scheduling extents of competence at different levels is realized based on following method:
Principle in line with " source maintenance ", the maintenance of grid equipment model and network topology structure is only provided the entrance of maintenance in its scheduling authority compass of competency, provide interpolation, the modification of device data, the means of deletion, the instrument that provides network topology structure to revise.In the present invention, to interpolation, modification and the deletion action of grid equipment model data, and the change of network topology structure, all be considered as the variable quantity information of electric network model.Behind the variable quantity Information generation, the vestige that retaining device and topological structure are revised generates the new database version based on all changes amount information.
Concrete, after province transfers the electric network model modification to finish, database latest edition based on all changes amount information, generation is based on the CIM/XML form of IEC61970CIM model (comprising its extended model) or the data interaction file of CIM/E form, is uploaded in the subregion regulation and control centre data platform by province's thread of adjusting a wage scale.Subregion regulation and control center is carried out the Piece file mergence of variable quantity model based on what the electric network model file of variable quantity and subregion regulation and control center generated based on the electric network model file of variable quantity in conjunction with what all provinces adjusted a wage scale that thread uploads, generation is based on the variable quantity message file at subregion regulation and control center, resolve for this variable quantity message file at subregion regulation and control center, generate the database latest edition based on all changes amount information at subregion regulation and control center.With legacy data storehouse versions merging, generated the meticulous electric network model of redaction that comprises in subregion regulation and control center and the each province's key degree authority compass of competency in the subregion regulation and control central dispatching extent of competence.By that analogy, upwards generate the whole network refined model that state more adjusts a wage scale by each subregion regulation and control center, follow equally said process.
In the process that above-mentioned electric network model is safeguarded, the problem of paying special attention to is the consistance in order to guarantee that threads at different levels are described electric network model in the same scheduling jurisdiction scope, version management for database will be take different scheduling jurisdiction scopes as the basis, the version that electric network model in each different scheduling jurisdiction scope is safeguarded unity at the thread of different stage, simultaneously, in the process of database version management, the time point information that maintenance release generates and the brief information of redaction data.
The present invention is in the whole network model maintenance stage, by many version managements technology of database and the source control that data are changed, realization is based on electric network model generation, parsing and the data file reciprocal process of variable quantity, guaranteed that data file mutual between the threads at different levels is minimum, the workload of Data Analysis is minimum, simultaneously, and based on the database version control of variable quantity information, guaranteed the minimum of storage space of database, data query is fastest.
Take a certain provincial power network model as example, the process that electric network model in self scheduling extent of competence is safeguarded is described, as shown in Figure 4.In to this process that electric network model is safeguarded inside the province, take the factory station as unit, safeguard the variable quantity information of this factory's station equipment.In the maintenance process of electric network model, the variable quantity information of initial all electric network models all is kept at buffer zone, before variable quantity information is applied to database, introduce the model mechanism that comes into force, after confirming that model comes into force, with all variable quantity information write into Databasces, generation is based on the database version of up-to-date variable quantity information, when the generating database redaction, preserve the time that version generates, be convenient to differentiate the data model version rise time that different threads at different levels are uploaded according to the time period in the whole network model.The introducing of the model mechanism of coming into force can be avoided the modification process of electric network model arbitrarily is applied in the whole network model.
After the integrated computational data platform of adjusting of threads at different levels is finished the maintenance process of electric network model in self scheduling extent of competence, realize the maintenance process to the whole network refined model, as shown in Figure 5.Judge whether interior all threads of network-wide basis have the latest data storehouse version based on variable quantity information, if having, the variation that electric network model is arranged in network-wide basis are described then, its variable quantity need to be applied to the whole network refined model.The process that is applied to the whole network refined model comprises that province transfers to the step by step application that subregion regulation and control center to state transfers, and the process of uploading is step by step uploaded the file interaction based on CIM/XML or CIM/E form step by step.
After the integrated computational data platform of adjusting of relay protection generates the whole network refined model, the market demand stage of threads at different levels, economize the integrated computing application of adjusting of accent as example take certain, illustrate based on market demand process of the present invention, as shown in Figure 6.Transfer the integrated requirement of adjusting and calculating according to state; in order to adapt to the demand of interconnected network; the calculation requirement of adjusting to relay protection device calculates based on the whole network refined model; can not do equivalent the processing; so when threads at different levels are adjusted calculating to the relay protection device in the affiliated scheduling extent of competence, all need obtain the whole network refined model.Economize adjustment with certain and surely be calculated as example, transfer request based on this province tuning state, the pattern of obtaining the whole network model is example, describes.After state transfers and receives the request of obtaining the whole network model, judge at first whether this province's accent obtains the whole network model for the first time, if obtain the whole network model for the first time, then issue the whole network model data, this province reconciles to analyse removes the electric network model that this province transfers all threads in addition, be saved to the database latest edition, database version was consistent during this version and state transferred.If not obtaining for the first time the whole network model, state transfer judge electric network model database version that this province removes all threads of this province beyond transferring in transferring whether with the state adjusting system in consistent, if inconsistent, be recorded as need to renewal state.Behind completeer all thread database versions, state transfers the up-to-date variable quantity information based on all threads that need to upgrade, generation is based on the CIM/CML of IEC 61970CIM model or the mutual files of CIM/E form, being issued to this province transfers, this province transfers all changes amount information is resolved, and generates the latest edition data that this province transfers, with original edition data storehouse models coupling, generate up-to-date the whole network refined model, carry out the integrated calculating of adjusting.
