[Abstract]:Distribution network is an important part of power system, which undertakes the task of distributing electric energy. Strengthening the intelligence of distribution network can improve the reliability and economy of distribution network and improve the power quality. As the intelligent data transmission channel of distribution network, the importance of communication system is self-evident. In recent years, wireless communication technologies such as Wi-Fi, Bluetooth and wireless ad hoc networks have become more and more mature, and these technologies have been applied to intelligent monitoring systems in distribution networks. It can overcome the difficulties caused by equipment dispersion and inconvenient re-laying of communication lines in substations. It also provides convenience for the extension and application of intelligent monitoring system in distribution network. Based on the above background, the intelligent monitoring system of distribution network based on short-range wireless communication technology is studied in this paper. Firstly, this paper introduces the principle of short range wireless ad hoc network, and analyzes its key technologies from three aspects: communication protocol, multi-hop technology and self-organizing process. Taking the short range wireless communication technology based on SimpliciTI protocol as an example, this paper focuses on the process of ad hoc network. Then, the structure of intelligent monitoring system of distribution network based on short-range wireless communication technology is presented, and the main tasks of monitoring main station, remote communication network and monitoring sub-station are introduced. The function and performance index of intelligent monitoring system of distribution network are expounded. The main function of the software platform is analyzed. Furthermore, the intelligent monitoring terminal of distribution network based on short-range wireless communication technology is developed. The intelligent monitoring terminal adopts the dual CPU structure of DSP ARM, which is connected by dual port RAM to improve the data exchange rate. The hardware structure and software system of the intelligent monitoring terminal are introduced in detail in this paper. Finally, a short range wireless communication mode is proposed, which is suitable for monitoring and controlling substation communication of intelligent monitoring system of distribution network, and its hardware and software system is implemented. The custom communication protocol of wireless ad hoc network is described in detail. The test and field test show that the intelligent monitoring system of distribution network and its wireless ad hoc network based on SimpliciTI communication protocol can meet the demand of intelligent distribution network and have a good application prospect.
