0 Introduction
In recent years, along with the computer technology, communication technology and database technology and the rapid development of power market, power dispatching automation system gradually formed [1]. However with the acceleration of urbanization process, a sharp increase in the scale of urban distribution network, distribution network structure is more and more complex, grid function demand increasing, so the current electric power dispatching automation system is difficult to meet the requirements of power distribution system. In order to solve the problems in the current power dispatching automation system, the research on the new technology of electric power dispatching automation system is imperative. Application of integrated technology in electric power dispatching automation system.
1 current power dispatching automation system
1.1 system platforms exist differences
In order to meet the needs of the rapid development of economy, the domestic distribution network were in-depth reform and planning, in order to adapt to the development of distribution network, power dispatching system must also carried out in-depth reform, especially the system function expansion and platform update [2]. The electric power dispatching automation system platform with distributed architecture, computer hardware platform is the bottom link. However, due to the platform selection of different types, different type has certain difference, which resulted in some differences exist between the electric power dispatching automation system of hardware platforms and operating systems.
1.2 power network model changes frequently
Country for the construction of distribution network is very seriously, and continuously to improve its operation status of the electric power dispatch system also changed with the occurrence of. However, the power dispatch system is very complicated, such as every one of the substation or its capacity expansion, power dispatch system must be re drawing, modeling and data entry, the workload is huge, very easy to make mistakes, so there is a big security risk.
1.3 functional requirements continue to increase
C A D A D, S PA and T S S are applied to the same power grid, but these functions are based on the respective independent database, which is called the separate modeling. Based on this, it is necessary to ensure that the same relative difficulty of the model and the database will have an impact on the function of the automation system. Therefore, it is very important to implement a unified interface between the power dispatching automation system and a variety of different functions.
1.4 information island problem
Electric power dispatching automation system is not to encourage the system, its operation process, the inevitable and other systems in power distribution network, many systems are very important for how to achieve efficient connection. Also for different levels and in different areas of dispatching automation system, operation is not completely isolated, each other also need to realize the information resources and sharing. But currently on the market that can provide many different kinds of automation products, different kinds of system structure and database exist certain differences, which lead to limited information sharing between different systems.
Application of 2 integrated technology in electric power dispatching automation system
In order to solve many problems existing in electric power dispatching automation system, we need to start from the reality, and develop the electric power dispatch automation system which is in line with the market and technology. This paper makes a deep research on the application of integrated technology in electric power dispatching automation system.
2.1 system platform integration
In the process of application of electric power dispatching automation system, the hardware and software system can be chosen to be different, and there are some differences between different types. In order to avoid the appearance of this kind of situation, it can be used in the middle layer technology, to build a platform to provide running and development of the environment, that is, the system application middleware platform [4]. concrete structure as shown in figure 1.
The intermediate layer essence belongs to the distributed software management framework, which can realize the good transmission of information, has a strong scalability, and can shield the difference between different systems. It provides a standard interface for power dispatching automation system platform, so as to realize the integration of the platform. The work principle of the intermediate layer is as follows: the client in the work process, need to obtain the required information or service from other systems, and these information or services may be located on different platforms. The client application only needs to transfer the needs to the intermediate layer, through the middle layer to the corresponding platform to obtain the client's needs, and then the information is transmitted to the client application.
2.2 system diagram
By the foregoing, to transform the distribution network, in the re modeling must be one by one to draw, establish a record and input, etc., the workload is complicated and complex, very prone to errors, but also consumes a lot of energy [5].
In the actual operation process, the power system of the equipment is not independent existence, has the relevant supporting equipment, that is often said the domain. In the power dispatch system, it is used to construct the common domain in advance, while the direct call is used, and the modeling steps are integrated, which makes the whole process simplified and greatly improve the working efficiency. The application function of the integrated technology of the graph is as follows:
(1) integrated graphics modeling
In electric power dispatch automation system, different application programs use the same database to edit software and graphics, so as to support multiple applications of different platforms. Drawing modeling software can achieve the following two functions: first, to be able to edit in real time; second, to provide information query and maintenance, these two functions are based on the task model. All the database can be modified in the execution state, if any one sub task execution fails, all the operations can not be performed. Edit mode as shown in figure 2.
(2) total station automatic mapping
Total station automatic function diagram for a modeling for power dispatching automation system into graphs provide convenient solutions, mainly from the following several aspects to reduce the workload: first, for different voltage levels corresponding layout of bus group to achieve the same, a definition of the same level of bus voltage; second, the equipment number in different domains formulated corresponding rules, equipment for realizing automatic and quick numbering; third, according to the layout of different voltage, position of each adjustment device ensure port anastomosis, realize automatic mapping; the fourth, can automatic generation part number and telemetry.
