Description
Technical field
The present invention relates to power technology field, particularly relate to a kind of electric power secondary system modeling method and system.
Background technology
Nearly ten years, the development of electric power system and information technology, the monitoring range of electric power secondary system (hereinafter to be referred as electrical secondary system) is constantly expanded, technical merit improves constantly.The progress of Information & Communication Technology (hereinafter to be referred as ICT) has become the great motive force of modern power network technical development, take present information and the communication technology as the constructed electric power secondary system in basis, in quite large degree, change the foundation structure of power infrastructures, become the important technology guarantee of electric power primary system safety, reliable, stable, economical operation.In the case, due to widespread deployment and the interconnection of electrical secondary system, the problem of the aspects such as its appearance such as physical security, security of operation, information security, all likely involves the stable of electric power system, affects the reliable power supply of electrical network.
Along with continuous increase and the expansion of intelligent operation main station system and digital transformer substation application, electric power secondary system hardware device is increasing, and business interconnection form is increasingly sophisticated, in the urgent need to building the Monitoring and Management system that meets electric power secondary system feature.
Supervisory systems is collected various service datas, such as electrical secondary system service operation state, secondary device operation conditions, network interconnection situation, system information safety, building environment parameter etc.Service data or Alarm Classification are showed O&M librarian use by supervisory systems.Because electric power secondary system technology is all multi-specialized across electric power system, automation control, computer science, communication technology etc., supervisory systems by Data Integration, offers the librarian use of different majors according to specialty.In the time there is resultant fault, need O&M personnel not only to there is higher level professional technology, also need to possess professional face quite widely.ICT industry has general safety management system, network management system etc. instrument at present, itself also has traditional monitoring module power industry production control system, supervisory systems can be by each side's Data Integration, but due to various supervisory control system business visual angle difference, monitoring range and analysis strategy are also different, the difficulty of coordinating analysis is larger each other, sometimes also can produce inapplicable noise data, affects the actual efficiency of O&M work.
Current supervisory systems majority is based on universal network management system extension, inherited the configuration modeling mechanism in the CMDB of universal network management system, and lower mask body is introduced this technology.
CMDB configuration modeling technique: the various configuration informations of equipment in CMDB (CMDB) storage and management enterprise IT architecture, it and all service supports are all closely linked to service delivery process, support the running of these flow processs, the value of performance configuration information, depend on the accuracy of related procedure assurance data simultaneously.In actual project, CMDB is usually considered to build the basis of other ITIL flow process and pays the utmost attention to, the success or failure of ITIL project with whether successfully set up CMDB and have very large relation.
70%～80% IT relevant issues and the change of environment have direct relation.Difficult point and the emphasis of implementing change management are not instrument, but flow process.By an automation, repeatably workflow management is changed, making, when changing when occurring, has a standardized flow process to go to carry out, and can predict this and change the impact on whole system management generation, and these impacts are assessed and controlled.And the realization key of change management process automation is exactly CMDB modeling.
As shown in Figure 1, operation system is split as from level to level correlation module and assembly by it to a typical CMDB allocation models, and ICT infrastructure and operation system are associated.Wherein modeling process is the classification of process configuration item, attribute definition, organization definition under clear and definite range of management prerequisite, is finally that concrete steps are as follows by configuration item instantiation:
CI classification: whole O&M objects is done to a logical partitioning so that management is distinguished management by its physical aspect.Utilize CI classification action, specify scope and the granularity of configuration management, one-level classification determines the scope of configuration management, and reclassify determines the granularity of configuration management.The design of CI classification, can farthest meet management statistics demand and various query composition flexibly.Utilize the intermediate link of CI classification as bridge joint attribute and CI example, be convenient to the structure CMDB of efficiency.By independent to structure and relation, be convenient to administration extensions and extension in the future, accomplish application foci solely point be convenient to safeguard and split, can play again the effect of efficient combination simultaneously.
CI attribute definition: for each CI classification, design attributes, so that CI example is inherited.CI attribute itself is with level (public, one-level, secondary, three grades).CI attribute has father and son's succession.CI attribute can be divided according to logicality (management attribute, technical attributes etc.), and each CI attribute needs design attributes value tied mechanism, fills in standard and efficiency, is convenient to follow-up statistics and calculating simultaneously.CI attribute has point (at technological layer, structure attribute, attribute of a relation also can be included attribute line management in) of narrow and broad sense.
CI organization definition: along with allocation models further excavates, considered at present further to deepen structural information, by original simple father and son's structure type, expanded to three kinds of structure types:
Form, father and son truly, certain module is the some of a program, such as CPU is the some of computer.
Connect (Is connected to), annexation between the two, such as the node of computer and network.
Need (Is needed for), the supporting role of a side to the opposing party, such as operating system and computer, project and a station server.
According to these three kinds of structure types, build CI cluster.
CI instantiation: complete after above three steps the pattern of model substantially definite, according to the initialization that is specifically monitored object and completes object instance, comprise the work such as the initialization of object properties, relation.
Can realize the top-down refinement of IT system is split based on CMDB modeling technique, form multi-layer C I object cluster, thereby support for management and supervision IT system provides basic model.
The limitation of CMDB modeling: first, CMDB modeling pattern is configuration information and the incidence relation take operation system as the various information technoloy equipments of unit description, in electric power system, between main station system and substation system, have between close longitudinal incidence relation and main station system and also have close horizontal incidence relation, this kind is associated in more difficult description in CMDB modeling pattern; Secondly, CMDB modeling pattern is focused on the decomposition of CI, it is a kind of static classification model, and what in the process of power system analysis electrical secondary system fault, pay close attention to is incidence relation logic or physics, and need to carry out cutting and reconstruct to model, need model to possess good dynamic characteristic.
In conventional solution, the method of taking configuration management object to decompose layer by layer for operation system, system decomposition is become to hardware and software, and hardware resolves into the concrete equipment such as server, graphics workstation, the network equipment, safety means, and for its common configuration object of every kind of device abstract; Same also can resolve into application and module one by one to software; And representing the deployment relation of software and hardware by independent CI inter-item relationship, Fig. 1 is a typical case of EMS system.
Wherein EMS system is disassembled as hardware components, as the HISserver in figure, PASserver, SCADAserver, the server of every type can also be refined into multiple servers, as SCADA1, SCADA2, can the computer configuration item of abstract its common configuration item for Servers-all type, comprise CPU, internal memory, hard disk, mainboard, operating system; SCADA subsystem branch is used for representing the deployment relation between hardware and software, and SCADA subsystem comprises SCADA and two application of ALARM, is all deployed on SCADA1 and SCADA2 main frame; SCADA program branches represents that SCADA application comprises two examples, and its functional module has comprised data receiver, data processing, data loading etc., can further refine to function point.Problem in this mode is:
1. a system need to be disposed three aspects descriptions from hardware, software and hardware and software will at least three branches, if the dependence between expansion software will be expanded a branch again, in the time that the angle of describing increases, numbers of branches can be a lot, redundant node is more, is unfavorable for regular maintenance and the expansion of model;
2. often there is the business relations between a large amount of boss station in electric power secondary system, can only in substation system and main station system, describe separately and the other side's relation in existing scheme, and the maintenance of relation is more difficult, the descriptive power of shortage cross-system;
3. the distinctive electrical network framework of electric power system, such as the compass of competency concept such as controlled area, Zi Kong district can only realize by the mode that increases branch in existing scheme, cannot on the whole the model entirety of each system be brought in the existing administrative mechanism of electric power system.
4. existing scheme is limited in one's ability to the auxiliary judgment of accident analysis, in above model, if certain assembly of certain hardware goes wrong, such as SCADA1 node cpu load too high, can date back to SCADAserver class server from its branch goes wrong, if but the module instance of further associated correlation subsystem must travel through other branches, this traversal in the time that model is huge (such as up to a hundred nodes, the system of a hundreds of module composition) inefficiency, thereby and cannot speed and accuracy that the fault effects scope of business is analyzed be reduced with other alarm associations.
