Therefore, we must accelerate the construction of enterprise information supply process to achieve automation of network operation and management, modernization. Grid Geographic Information System to the entire power system equipment in the visual environment to manage, make scientific planning, specification design, to improve the security of grid operation, improving economic efficiency, to achieve the overall management of power production.

First, the power GIS Overview
GIS (Geographic Information System, GIS) is a decision support system, with various characteristics of information systems. It with other information systems, the main difference lies in its stored information is the result of geocoding. Location and with the characteristics of the location attribute information about the surface features become an important part of information retrieval. GIS can be considered as a technology, a tool. when such technology or tool to be used for specific areas, services to specific objects, they used a more the exact name, geographic information systems such as power, urban geographic information systems. These applications can be seen as specific applications of GIS technology to join their own special skills or special way. This paper discusses the power of geographic information systems, the power GIS. first discuss the necessity of introducing power GIS, objectives and development goals.

(A) the need for
Power production of products, "power" of the continuous, dynamic characteristics, determines the transfer of production between the various departments of information does not allow any mistakes. Must be established between the various production departments tight, fast communication, sharing mechanism, supply the various departments involved in producing their own data, information and timely communication to all the data needed to carry out the work of the departments and positions. The traditional management of the comprehensive production information exists, unity, sharing, use, timeliness, and poor accuracy, and therefore need to establish a production and business management aspects of supply cover, throughout the entire production process grid GIS, also known as power production and integrated management information system Diao million, with the aid of geographic information intelligent graphics power graphic graphic information management and network management functions coupling facility, the production of power supply enterprises of different sectors of the different staff members to provide collaboration tools to process information.

(B) Purpose
Power of geographic information system development aims to improve the level of power of modern management, to improve power supply reliability rate services for electricity, transmission, substation, distribution, planning, design, scheduling and communication of the service, and enhance supply enterprise competitiveness in the market. through the management of geographic information system grid, so that the whole power supply management of all aspects of production are in a controllable state.

(C) the goal of building
1. By introducing spatial information technology, integrated management of power production and management need to describe the device attribute information, equipment, information and network topology spatial relationship information, from the technical means to solve the traditional block system, regional limitations brought multiple data sources, data consistency problem of poor and sharing.

2. Dispatching automation with SCADA systems, lightning location system, electric energy billing system, MIS system, seamless and integrated into network planning, pollution distribution and the power marketing and other professional information management, and static information and dynamic the integration of professional information to complete the intensive electricity production information management.

3. For the power authorities to provide effective tools for advanced decision support. To improve grid reliability, power industry, management level and efficiency, and improve situations in the accident rapid response capability and establish corporate image for the enormous economic power enterprises and social benefits.

In short, the power of geographic information systems for the power sector, network planning, load forecasting, to install the program, run a number of network analysis and calculation methods and different business development programs to provide powerful tools for advanced decision support. Use of GIS, can grid network, power supply facilities, location, equipment management unit and a variety of data equipment and flexible information query grid accurately, statistics; use of GIS, to create a dynamic network model. When the grid fails, the network topology analysis, to quickly identify the fault location and equipment, visual indication of the scope and positive and negative power supply query to provide the best repair path, and the loss of statistical power; use of GIS, can be asset management, equipment maintenance, the transmission, substation, power distribution, communications and measuring equipment management standardization, systematic and scientific, thereby improving the management level of production equipment; use of GIS, line loss can be calculated, the reliability of basic data and statistics in its work; use of GIS, attribute data through the network equipment and operation of real-time data and geographic data of the perfect combination of power network information visualization to maximize the operation of power management and safe operation level.


Second, the development and application of GIS need to grasp the power to be part of several tribute
GIS in the power supply production management, especially the prominent use of network management performance, many power companies have accelerated the development of geographical information system and application steps. But because of geographic information system for the application of each enterprise managers and staff to stresses are a brand new technology, so we must act on its development and application of several important aspects, which for the system construction and smooth operation of long-term security are very important.

(A) Select the premise of practical advanced foot platform
GIS platform, including hardware platforms and software platforms. For the GIS hardware platforms, most of the generic products are used, so choose the practical advanced software platform is vital. Software platform embodied in the practical advanced open platform and practical upper. reposted elsewhere in the Research Papers Download http://www.hi138.com open platform, including an open system architecture (application level, open, open system management, system development and opening up); system support open technology (common development language, industrial graphics library and interface interface standards, common database systems); data structure of the open (open the internal data format, standard external exchange format). platform availability, including the platform for application functionality to meet the electricity sector, the application of customary and production of the basic rules of relevance and applicability of stronger; platform software system should have a convenient and practical for users to develop tools that can effectively use existing resources and reduce the input.

(B) of the GIS system to improve power availability foot Key
GIS development and construction of electric power system is aimed to solve power problems in production management, to better improve the modernization level of management, better production and service. Therefore, should improve the system's utility as the system development and construction " soul "task. to achieve a practical system, built with a good system must pay attention to the following four points:
1. Made a complete functional requirements. For the work function of the actual demand is made complete basis for system development, but also to ensure the application. So in the Research, the developer must fully communicate with the production and management, and guide them according to actual production, rational, scientific, complete presentation of functional requirements.

2. To ensure the authenticity of the data. For the data processing power as the main function of GIS is concerned, there is no real and reliable data, the system became a "shell", became a "display", there is no value. So must ensure data is valid. to ensure that the data reflect the exact position of geographical space. to ensure that thematic attribute data (ie network information) is accurate.

3. Focus on business process reengineering. Open GIS application of power is bound to the traditional production business process impact. Which requires power companies do not meet modern production on the original direction of development does not meet the future advanced information management model of the old optimize the business process integration, to make it more scientific and reasonable. business process reengineering will inevitably bring changes in organization and personnel, involved departments and the vital interests of staff. To eliminate possible "artificial obstacles", the most direct and effective way is to raise awareness of the importance of GIS with the power and necessity of understanding. Many examples show that people are thinking the problem is not resolved, do not touch the production and business process changes, the practical goal of the system can not be guaranteed and realized.

4. A company and developer of the long-term cooperation mechanism. GIS as a business power to the computer and information technology as the core of the new system, under the impact of information technology development, technology updates will soon face, short life cycle of the challenges and pressures, and these alone can not deal with the enterprise itself. Therefore, the establishment of corporate long-term cooperative relationship with developers on the enterprise, the developers are very important. This is to ensure that system availability is an important measure.

(C) adequate basis for improving people's quality
Power GIS system development aimed at applications, and use the key to a good system of people, that people understand and master the application of technology. Therefore, improving the quality of personnel is a system construction, application, maintenance must grasp the basic link. On the quality of corporate officers, up to three levels to improve: First, improve the quality of business leaders, so leaders attach importance to system construction and application of firm "to use" thinking; two primary applications is to improve the quality of personnel, improve production management the application of skills to address the "will use" issue; third is to improve the quality of system management, enhance the level of management and maintenance to ensure system operation "can" issue.

(D) establish a sound management system is to protect
GIS is an advanced power management means of production, from development, construction, application of the process itself to the management level of enterprises put forward new and higher requirements. Only to establish a sound management system, to ensure the smooth construction of the system and running smoothly. For this reason, it is necessary to establish a strong lead agency, to achieve the organization's assurance; second is to train high quality technical personnel to achieve technical assurance; third responsibility was to develop a clear responsibility, management goals; Fourth, the introduction of technology to develop operating procedures to standardize management; five regular maintenance to improve the system of secure management.

In short, only more attention and focus on four important areas, the construction and application of electric power GIS can be guaranteed. Links http://www.hi138.com Research Papers Download
