[Abstract]:In the substation automation system, the communication manager is responsible for the interconnection of different communication networks and the conversion between different communication protocols, and solves the problem of interoperation within the substation automation system. A communication network with high stability, expansibility and fast processing of information is constructed for substation automation system. It is a communication hub between substation monitoring center, remote dispatching center and intelligent electronic equipment. Communication protocol conversion is the most important function of communication manager. In this paper, the Ethernet-based 104 protocol and the 103 protocol used to protect the equipment used in the dispatching center are deeply studied, and the 101,103,104 protocol is implemented in the communication manager. Conversion between CDT and MODBUS protocols. Based on the study of a large number of literatures, this paper analyzes the functions and performance of the communication management machine, and studies the design requirements of the hardware and software of the communication management machine. An embedded real-time operating system 渭 C / OS-II based on STM32 platform is proposed. The design scheme of communication management machine can be realized through various communication protocols and communication interfaces. The communication manager has the characteristics of small volume, low price, reliable performance, and can deal with a large number of real-time information quickly. It can support 101 / 103 / 104 / CDT / Modbus and other communication protocols according to the needs of the field. Serial RS-485/232 communication bus and Ethernet based on TCP/IP protocol can be used in communication medium. WEB server module is integrated inside the system. The user can configure parameters through WEB browser and monitor the real-time running state of the whole system. The communication management machine designed based on this scheme has good real-time, high efficiency, extensibility and reliability. It has been tested and put into operation on the spot. The test and operation results show that the device has a good performance-price ratio, can meet the field engineering technical requirements, and greatly improve the overall performance of the internal communication of substation automation system.
