[Abstract]:In recent years, remote automatic meter reading system has been gradually established in various parts of the country for remote meter reading. However, in some old residential areas and along the street, users in distribution network stations are confused, inaccurate or even missing. It seriously affects the normal functions of the remote automatic meter reading system, such as accurate management of users in the station area and fine statistical analysis of line loss of the station area. In order to solve this problem, this paper presents an intelligent identification system for distribution station users based on carrier communication technology, which can be used to identify the relationship between distribution transformers, collectors and users in the distribution network, and display the identification results in the remote monitoring center. In order to solve the problem that the accuracy of existing recognition algorithms is not high, this paper also puts forward some intelligent algorithms, such as ant colony, genetic and BP neural networks, which can solve the problem of accurate identification of user information in complex circuits. Effectively improve work efficiency and recognition accuracy. Field test shows that the on-line recognition rate of the recognizer is 97.7. the hand-held instrument can realize the identification of all the user information, which proves the feasibility of the scheme and the reliability of the system. In this paper, the following research work is carried out, and the structure of intelligent identification system for distribution station area is built. The intelligent identification system of distribution station area consists of upper computer, recognizer and handheld instrument. The recognizer identifies all the information of the collector in the station area by the method of active report of broadcast communication, and the handheld instrument recognizes the information of a specific collector or a user by means of passive inquiry method of point-to-point communication. The identification results are transmitted to the upper computer of the remote monitoring center by GPRS remote communication mode. The hardware design method of the intelligent identification system for distribution network stations is studied. In order to facilitate the installation and debugging of the system, the hardware of the system adopts a unit design scheme, which can easily change the circuit design and replace the circuit unit. The common hardware unit of the recognizer and the handheld instrument mainly consists of the main control board unit, the GPRS remote communication unit, the power supply unit and the bottom board unit. The main difference is that the recognition instrument adopts a three-phase carrier communication unit. A hybrid routing algorithm for distribution network carrier communication based on ant colony is studied by using single phase carrier communication unit. 3. In order to further improve the reliability of power line carrier communication, the algorithm introduces the number of hops, delay and packet loss rate into the cost of path overhead, which is constrained by the distance between two nodes and the quality of the communication signal. Under this condition, the routing with minimal overhead is solved. In addition, the ant colony algorithm transfer rule and pheromone update rule are further improved, and the genetic algorithm is used to initialize the population, and the simulated annealing algorithm is used to solve the internal closed-loop problem of genetic algorithm. The precocity phenomenon. 4 can be avoided effectively. The intelligent recognition method of distribution network based on BP neural network is studied. The auxiliary applications of the recognizer and the handheld instrument can be used to identify the identified user, the unrecognized user and the cross-station uncertain user through the carrier communication technology. Based on the power carrier signal quality and the forward BP neural network, the handheld instrument can improve the accuracy of station area user identification, realize the full identification of station area user .5. the system test of distribution network station area user intelligence identification system is carried out. The test results show that the recognition rate of the recognizer is as high as 97.7after the field identification of the instrument and the handheld instrument. The system has good field function and performance, which can meet the requirements of the users and phase information in the survey station area of the power company.
