[Abstract]:Intelligent substation is the trend of substation construction nowadays. The acceptance of intelligent substation is an important guarantee for the safe operation of intelligent substation. The digitalization and networking of intelligent substation communication bring difficulties to the functional acceptance of the secondary system of intelligent substation. At present, the function acceptance is mainly completed by the personnel in the form of dialogue, which wastes a lot of manpower and time cost. The advantages of intelligence are not realized. At the same time, there is no user interactive software for the function acceptance of the secondary system of intelligent substation in the electric power industry. In this paper, aiming at the problem of functional acceptance of intelligent substation secondary system, the function acceptance model, model instantiation algorithm, acceptance completion rule, program logic realization of intelligent substation secondary system are studied. A new intelligent software acceptance method is proposed to solve the complex and time-consuming problems in the process of functional acceptance of the secondary system of intelligent substation. The main contents of this thesis are as follows: (1) the information model of intelligent substation equipment and the communication network structure of secondary system in intelligent substation are studied in IEC 61850 standard. Based on SCD file and relay protection principle, the function acceptance model of intelligent substation secondary system is constructed, and the database access middleware is used to construct the acceptance template library. (2) the instantiation algorithm of acceptance template library is studied. Based on the intelligent station information model generated by parsing the SCD file and the weight matching algorithm proposed, the acceptance template library is instantiated. The database access middleware is used to realize the establishment of acceptance case library. (3) the application algorithm of acceptance case library is studied. Based on this algorithm, a set of simple operation is developed. The function acceptance evaluation software system of intelligent substation secondary system with strong interaction is developed, and the acceptance evaluation of the secondary system function of intelligent substation is realized after analyzing the network message. The acceptance evaluation software system developed in this paper has the advantages of automatic matching of acceptance items, no sequence of acceptance and intelligent confirmation of acceptance results at any time. The use of the system will greatly shorten the acceptance period of intelligent substation and save the acceptance labor cost. At the same time, the research work done in this paper will also provide technology accumulation for intelligent substation acceptance.
