The Scheduling Management Information System (DMIS) scientific comprehensive analysis and statistics deal with the professional information of the dispatcher's internal operators, dispatching, relay protection, communication and automation, and can provide strong support for leadership decision-making. The main body of information management is the assistance of the security and production of the dispatching department, office automation and team management. The information management framework is the human, financial and material used in the dispatching department, and the virtualization of the relationship between the object and the managed object in the dispatching department is fully constructed. The information model space provides an efficient and smooth modern information flow channel for the management, production and operation of the dispatching station. To provide various kinds of useful information and modern management tools for the leaders and departments of the control center to ensure the scientific decision-making of the functional positions of the dispatching department, so that the DMIS information networking and data sharing of the dispatching department's upper and lower levels of the system can be realized. The correct application of the management information system in the dispatching production management can greatly improve the professional work level of the dispatching center and improve the business efficiency of the dispatching department.
1 information system structure
The database and network technology are used to form the power dispatch management information system. The network-based management information system is built in the power supply company, and the daily operation of the computerized management and dispatching department is realized. The network and non-writing of the dispatch management are realized, and the MIS system is integrated. The management personnel of the dispatch management and dispatching department can accurately and timely grasp the relevant information such as power outage maintenance and production data through the network, provide an effective and true information basis for the leadership decision, ensure the paperless of the dispatching information, and realize the automatic management. The dispatch management gradually transformed into the computer information management stage. The basis for ensuring that the grid can operate normally is the power scheduling data security. However, some power information such as power outage range and power outage time must be published in the society, which leads to further intensification of the contradiction between the publicity and security of the dispatch data, and in order to completely solve this contradiction, the information system has to be based on the Web. A three-tier architecture and a server-based client structure can be implemented. According to years of management experience and research experience, it can be found that the management structure in the dispatch management information system widely used by power companies in China mainly has two kinds of management structures based on server/customer system and management structure based on WEB three-tier system. The various structures complement each other and provide support for power dispatch management.
1.1 Based on server/client architecture
The information technology application based on the server customer architecture is applied to the scope of the power system, and the confidentiality and security of the data must be fully ensured. The system specifically includes a) using a large commercial database—DH2; b) using Windows200NT as a development platform. Based on the internal LAN of the enterprise; c) multi-level authority to manage all users; d) implement networked process management to apply the server/client architecture to the database, and place the database on the server side, the database server can help customers The machine analyzes and calculates the corresponding data. The client is mainly responsible for providing the data to the user, effectively contacting the database and the user. Each customer can effectively share the data in the commercial database in the server by effectively connecting the server and the local area network. The main feature is openness, which provides database support and computer network platform for decision support system and office automation system.
1.2 Web-based three-tier architecture
The three-tier architecture based on the Web runs outside the power system, and the shared power information mainly includes
Some remote users adopt the Web architecture to access related databases through browsers; 2) Power public information adopts Web architecture, and publishes information to the society through browsers; 3) Comprehensive information adopts Web architecture through browser mode Provide supportive decision-making to leaders using multi-level user rights management to ensure networked process management is achieved.
Due to the further development of the Internet, some power dispatching public information must be announced in the network. In addition, the LAN used by each power supply bureau is gradually expanding from the internal scope of the bureau, and the power dispatching station and data management gradually It has become a new requirement for modern information management systems, and many users have put more stringent requirements on system performance. Therefore, for the corresponding functions of remote users and information announcement requirements in the network, it is more suitable to use the three-layer architecture based on the Web to ensure that the system is more powerful. The management information system applicable in the municipal power supply bureau enables the Web through JSP. The way is achieved.
2 system functions
The main purpose of developing information technology in power dispatch management is to be able to effectively dispatch power systems. According to the actual production division, the key points of the dispatching work should be fully utilized to ensure the operation of the ticket, power outage application form, and payment. General functions such as succession record, operation task ticket, maintenance signage, daily operation analysis, capacitor operation record, main change sub-head adjustment record, etc., such as browsing, input, statistics, query and printing, are guaranteed in the network. The circulation of various roles such as the power outage application form is realized.
2.1 User Login
Confirm the user role when entering the system.
2.2 Power outage application form
The use of the power outage application form user role specifically includes the "application unit supervisor", "applicant carrier", "following insurance", dispatching director", "dispatcher", "communication" and "remote action" systems, etc. It is automatically generated, and the application number is automatically generated according to the rules. According to the specific operation requirements of each role, the role user is allowed to operate different options to realize the circulation of the roles of the power outage application in the network. If the application reaches all links, the user needs to be Timely reminders are issued. Each user can query and browse the power outage application form according to the conditions, and check the specific implementation of the monthly power outage application statistics, including the plan execution rate and the pass rate, but no permission to operate. For power outage requests during the transfer process, except for the corresponding role users, no one else has the right to edit them.
2.3 handover record
The operation system, the signboard assembly and disassembly records, the installation and disassembly grounding line records, and the opening and closing records are recorded in detail. The information system can automatically record the name of the shifter and save the next shift record and automatically generate it.
2.3.1 Entering the shift record
Only the dispatcher who is on duty has the right to enter the record of the shift. The specific records include the installation and removal of the grounding line record, the system operation, the open work record, the signboard assembly and disassembly record, etc. The successor can only enter the password. Signature, after completing the above operations, the system will automatically record the name of the shifter, save the shift record, and automatically generate the record that will be taken over. The successor will continue to input the operation authority. Once the shift is successful, the shifter must not modify the saved. record of.
2.3.2 Query and browsing history
Each user has the right to query and browse the history. The history record can be queried according to one or more conditions such as "the shift time of the shiftee" and "system operation". The system can be used in the form of keywords. "Implement a fuzzy query, select the query result record, double-click it to open it, and browse and view its detailed content.
