Description
Technical field
The present invention relates to the integrated EMTDC models integrated application of high voltage DC engineering, based on WEB server to high-voltage dc transmission
Electric system technological document data and its EMTDC Unified Model empowerment management.
Technical background
PSCAD/EMTDC is Canadian Manitoba direct currents research center to specialize in the D.C. high voltage transmission of locality
System and a powerful electromagnetic transient in power system simulated program researched and developed, through constantly exploitation and perfect,
Become one of outstanding electromagnetic transient simulation software suitable for the numerous research fields of power system.At present, EMTDC simulation softwares exist
Extensively apply in high voltage DC engineering both at home and abroad, especially the system integration research of DC engineering early stage.
In the several high voltage direct current transmission project construction of south electric network and the technological development of team design autonomy-oriented and engineering reality
During trampling, Nan Wang Research Centers are progressively grasped to the EMTDC models of high voltage direct current transmission project, are needed to the system integration
Emulation platform carries out induction-arrangement, and is applied to Overvoltage and insulation coordination research and controls protection mechanism deeply investigate.For this purpose,
EMTDC platforms integrated application exploitation integrated to high-voltage direct current is studied, and HVDC system is managed using data base
Unite the principle of integrated EMTDC models and its main application, method, engineering project information bank, develop a set of employing WEB interface model
The EMTDC integrated platforms that library management, mandate and function show.
The content of the invention
It is an object of the invention to provide a kind of integrated EMTDC integrated application platforms of high-voltage direct current, the present invention will be existing
Some HVDC technology EMTDC models carry out induction-arrangement, using WEB interface model database management and database server pipe
Reason, with safeguarding and upgrading mode is simple, cost is reduced, selects more advantages.
The technical scheme for realizing above-mentioned purpose is：
The present invention the integrated EMTDC integrated application platforms of high-voltage direct current, in include by client computer, application server and
Three part of database server constitute, three parts using three layers of B/S structures based on middleware framework, wherein：
Client computer uses main body for platform, using telnet mode, server and data base is conducted interviews, by opening
Putting property interface enters line search or modification to server and data base；
Application server realizes that using WEB application program web application is one group of static set with dynamic Web page,
Static Web page is such a page, and when site visitor asks this page, it will not occur to change Web server by this page of transmission
To request Web browser, and which is not modified, conversely, dynamic Web page will be just being sent after the modification of server
To request browser, it is the reason for being called dynamic that page occurs the characteristic of change；
Database server is equally based on WEB and provides unified data base administration, backup, starts and recover function, data
Storehouse server is data management and processes work and branches away from client computer, enable each computer on network resource it is each to the greatest extent its
With, network overhead is substantially reduced, coordinated manipulation reduces resource contention, it is to avoid deadlock, there is provided on-line equiries optimization mechanism.
Analyze according to demand and the main application characteristic of platform, the function of Platform Designing includes 5 aspects：User management, text
Part management, technical management, message system and engineering management, five functional block are cooperated with data base, are constructed individual perfect
Platform management system.
Analyzed according to modules functional requirement, modules will have different functional requirements and model data, each mould
Block is considered as managing concentratedly, is distributed the pattern for using.
According to demand, user's registration and user's log-in module are devised, user is divided into three ranks：Domestic consumer, technology
Manager and system manager, wherein：
System manager：Highest weight limits the use of family, is responsible for being managed the state of technical management person and domestic consumer, is responsible for
File and engineering state are managed, are generated by system；
