[Abstract]:The first base of smart grid realization is the intelligence of substation. Under the background of continuous development and popularization of intelligent substation, this paper aims at the working method of the key link of debugging and acceptance of intelligent substation monitoring system. The technical means and field practice are deeply considered, explored, researched and practiced, and more effective methods are put forward according to the situation of field work and power grid construction. The main work and new ideas of this paper are as follows: (1) in the context of the continuous promotion and development of smart grid, the development course of intelligent substation is reviewed and evaluated in detail, and combined with a large number of field research and practice, As well as referring to the research results of the peers, this paper summarizes and analyzes the research progress and actual situation in the related fields of intelligent substations, which has certain reference value.) according to the current situation of intelligent substations, The purpose, function, main contents and existing debugging methods of intelligent substation monitoring system are described in this paper, which revolves around the structure of three layers and two networks of intelligent substation monitoring system, and the summary and summary of main functions. This paper analyzes the nature of debugging and acceptance from different dimensions, such as the nature of the verified project, the key position, the process and so on. At the same time, it is expounded that although there are already many sets of acceptance codes at present, the problems of idealization, isolation, incompleteness, repeatability and so on in the field interpretation and implementation, In view of the problems existing in the debugging and acceptance of intelligent substation monitoring system, this paper puts forward a direct networking method for the commissioning and acceptance of intelligent substation monitoring system. Direct networking method has the characteristics of short period, high efficiency, low repeatability and project refining. Although the method has some problems, such as tight working schedule and complicated regression test, it can improve the working efficiency and quality in the field engineering application. It has certain popularizing value to advance the commissioning and acceptance work of intelligent substation. Aiming at the deficiency of the direct networking method, the improved method is further put forward. The core of it is to seek the improvement idea and practice of debugging and acceptance of intelligent substation monitoring system from two directions of drawing and tools, and to make up the deficiency of direct networking method effectively. By analyzing the phenomenon of "digital loop" in intelligent substation, the concept of full information loop diagram is introduced, and the method of making it is provided. The purpose of this paper is to realize the centralized collection of digital information in the whole intelligent station monitoring system. In this case, in addition to realizing the visual display of customization, the automatic test tool can be developed by using the information itself, and the integration of SCD files can be realized quickly. Spacer equipment monitoring, rapid problem location and other work. In a word, with the rapid development of information, automation, network and other technologies, intelligent substations naturally have the conditions to link up with this trend, the full information circuit diagram and its derivative tools. It will become the development direction of substation advanced application test technology.
