Refer to issue, by load type division, analysis modeling, model registration, the part realization that these three are sequentially connected and load scheduling is divided
Analysis is split, and is packaged into the module after splitting using modelling technique, Web Service technology and SOA framework relatively independent
Model, Multitype modei be integrated to form model, and the registration by Axis2 technology and UDDI technology implementation model and sending out
Cloth is so as to become the service that can externally apply.
Two is scheduling scheme module construction, is on intellectualized analysis platform, draws electric load lexical analysis business side
Case figure, with to draw business process map on visio similar, the accumulation of polytype conceptual scheme forms scheme picture library to this figure, together
When, by imposing a condition, model in customizing model, and model is added to realizing servicing in position corresponding in conceptual scheme
Build.Can achieve report generation by clicking on each model, different service themes forms theme storehouse.
Firstly, for the structure of analytical database, by building to the Module Division of electric load lexical analysis business, analysis
Mould, model registration, form analytical database, provide base library for efficiency evaluation service construction, including the following aspects：
1) Module Division
Conventional electric power load tuning control system is often directed to a set of autonomous system of a certain regional development, application is not carried out
Module Division, directly gives last application result, also not from the aspect of the portability of final system, extensibility.Mould
The main purpose that block divides is on the basis realizing efficiency evaluation function, facilitates system transplantation and extension；Meanwhile, module
Divide and make the links applied be all transparent, convenient system maintenance.Why Module Division is capable of system
Transplanting and extension, main cause is as follows：
After Module Division, system is made up of multiple application modules, and each module has certain function, then if system needs
Extend, then only need to increase new module, module originally can not change；If for same type of area, big portion
Point application module can be general, only need to remove unnecessary module, and increases a small amount of module newly, thus greatly reducing exploitation
Amount, system can also be realized transplanting well；If system needs to modify or update, only functional module to be changed need to be entered
Row updates, and does not change other modules, so that the workload safeguarded is preferably minimized, greatlys save cost, it is to avoid waste, real
Show energy-conservation.
The size of module is the factor firstly the need of consideration for the Module Division, and whether block size divides and be rationally directly connected to
The transplanting of whole system and extended attribute.Legacy system exploitation can consider and for whole system to be divided into a big module, thus
System is made to be difficult to extension, the therefore division of module can not be too big；Meanwhile, the division of module is not the smaller the better, module
Whether division can should be shared as standard with this module, and some Module Division are out also never shared, then only can increase
Plus workload.
The function of module is the Primary Reference foundation of Module Division, and the division of module first has to ensure that this module is capable of
A certain function in operation system.Meanwhile, the function of module be determine this module can be shared primary condition, therefore,
During Module Division, Module Division should be considered it is ensured that the module dividing farthest shares from functional perspective.
2) analysis modeling
Analysis modeling mainly adopts modelling technique, Web Service technology and service-oriented architectural framework (SOA)
Become, analysis modeling will ready-portioned application module, using the correlation technique of analysis modeling, be packaged into model, be intelligence point
On analysis platform, realized by the way of model buildings.Analysis modeling is actually that the sequencing of business application module is real
Existing, analysis modeling correlation technique mainly has modelling technique, Web Service technology and Services Oriented Achitecture.
Model has the characteristics that：1st, reusability and interoperability are strong.Reuse is the greatest feature of model, refers to complete a certain
During system, the software of multiple modules can reuse, and realizes without again writing code；2nd, realize details transparent.Model
In running, input and output interface are entirely transparent, and its realization and function are kept completely separate, hence for application mould
For type, it is only concerned input and two interfaces of output, need not be concerned about inside model；3rd, good extensibility.Each mould
Type is all independent, has its exclusive function, and if desired model provides new function, for model, only need to increase interface, not change
Become original interface, thus the extension of implementation model function；4th, plug and play.The use of model is similar to play with building blocks equally,
Can build at any time, use at any time；5th, exploitation is unrelated with programming language.Developer can select any language development model,
As long as meeting model development standard, can be issued using binary form after model compilation, it is to avoid source code leaks, protective development
The copyright of person.
Web Service is a kind of model establishing techniques, and it adopts XML format encapsulation of data, and itself function is retouched
Adopt WSDL when stating, meanwhile, want the various services providing using Web Service it is necessary to register to it, it is possible to use
Realizing, the transmission of data between model is carried out UDDI by soap protocol.Web Service has and platform and exploitation
No matter the unrelated characteristic of language, being based on what language and platform, as long as specifying its position and interface, just can pass through in application end
SOAP can realize calling of interface, obtain return value simultaneously.
3) model registration is issued
So that ready-made model is used it is necessary first to the model of exploitation is packaged into Web service, carried out using Axis
Packing.Axis is exactly substantially a SOAP engine, provides the basic subrack creating server end, client and gateway SOAP operation
Frame, can have the ability in foundation and operating to dispose Web service simultaneously.After Web service is formed, this service is uploaded to service
Device, meanwhile, by UDDI (a kind of directory service, area can be registered to Web services using it and be searched for) to this
Web service is registered, and can use Web service, final Web service is exactly model in fact after registration.
Secondly, for scheduling scheme module construction, scheduling scheme module construction be based on intellectualized analysis platform on, draw
Electric load lexical analysis operational program figure, meanwhile, specified criteria, customizing model, adds to conceptual scheme, click model, you can
Realize application.Scheduling scheme module is to be built on the basis of business library, and business library once building, only need to exchange by the later stage
Degree scheme module is changed can achieve the rapid build of service, including the following aspects：
1) drafting of conceptual scheme
Draw operation flow conceptual scheme, need to load scheduling analysis be well understood by, simultaneously it will also be understood that each model it
Between joining relation, the preferably developer of model, otherwise need the detailed description of each model, the input of model and output and
Function introduction etc..Operation flow is drawn on intellectualized analysis platform, draws similar on Visio, very simply.Dissimilar
Conceptual scheme eventually form scheme picture library, thus facilitating shared between different application service.
2) scheme customization
Efficiency evaluation scheme customization procedure is very simple, enters model by platform, selects the model needing, preserves after name
To corresponding position.
3) report generation
By drawn conceptual scheme, each node of corresponding scheme in figure, corresponding model is added node, so
After preserving afterwards, you can operation service, the service of different themes ultimately forms application theme storehouse, realizes between different application theme
Shared.
Above disclosed be only several preferred embodiment of the present invention, certainly the power of the present invention can not be limited with this
Sharp scope, the equivalent variations therefore made according to the claims in the present invention, still belong to the scope that the present invention is covered.
