With the development of the economy and the improvement of people’s living standards, the demand for power quality and power supply reliability of the power system is getting higher and higher. The development of distribution network automation is an important measure to improve the quality and reliability of power supply, involving primary power equipment and substations. , opening and closing stations, line monitoring and control. At present, cities in China generally do not form a complete multi-channel power distribution network, mainly to convert a single-power radiating network into a dual-power ring network. The use of a dual-power ring network power supply scheme can greatly improve power supply reliability. Currently, a large number of devices such as on-column switches, RMUs, reactive power compensation devices, meter reading devices, and controllers with RS-232/422/485 serial communication interfaces are used in these power systems. Most of these devices have not achieved centralized monitoring and can only be used for local display and control. Only a few key points have been remotely monitored by telephone dialing, but they cannot be monitored in real time. Therefore, the disadvantage of the existing system is that it cannot monitor data in a centralized, comprehensive, accurate and real-time manner.
With the large-scale use of Ethernet in the commercial field and the rapid development of network automation, users and suppliers urgently need real-time access to data and control at any time and any place, enabling remote fast failure analysis and processing, and equipment. The remote maintenance in order to improve the quality of power supply, improve the power consumption indicators, improve the efficiency of power supply companies and reduce overall costs. In China's current power supply situation, this is a very broad demand for electricity market. It can be seen that the communication connection between RTU/FTU/TTU in distribution network automation is moving from traditional serial communication, wireless communication and power line communication. Ethernet direction changes. For distribution automation in power systems, the communication medium of Ethernet is the most commonly used optical fiber. Compared with the twisted-pair wires often used in office environments, the use of optical fibers can achieve long-distance communication and high electromagnetic interference immunity.
Communication uses Ethernet, but a large number of RTU/FTU/TTU devices still only have serial ports for communication. How do you connect these serial devices to the network? How to protect the large amount of capital that power companies have invested in these devices? Obviously, it is neither economical nor feasible to completely replace these smart devices with serial communications. For these practical needs of power distribution automation, the use of serial device networking servers is the best solution to these problems.
Orient Digital Solution For the existing RMUs, reactive power compensation devices, and meter reading devices, a large number of devices with RS-232 communication ports can be passed through Dongfang Digital's C2000 server (1 RS-232/422/485 serial port Device Networking Server) These devices are formed into Ethernet. In this system, the instrument and Intranet/Internet are connected through the C2000. This intranet/Internet connection can be achieved via standard Ethernet cables, a modem/phone line, or a wireless modem such as CDPD. Now, with this connection, remote systems with application software can access field devices over a standard network. With Intranet/Internet connection, a PC with browsing function (which can be a desktop computer, PDA or thin client) can remotely access the serial device network server and connected RMU, reactive power compensation device, and meter reading. Devices and other equipment, either directly for data monitoring, can also send control data to the site equipment. The use of Dongfang Digital's serial device networking solution enables the use of Ethernet communication in power distribution automation to become a reality.
Why use C2000? The C2000 is small and compact, with only the palm of the hand. It is suitable for installation around field devices. It can support master-slave mode (so that the host can directly access the serial devices on the site). It also supports peer-to-peer connection, or active data reporting, and multiple operations. Mode to meet the actual needs of users
l supports Windows 95/98/ME/NT/2000/XP also supports a variety of UNIX/Linux operating systems, users can use my company's driver program can also be programmed to achieve a variety of advanced features.
l There is no need to change the existing software and equipment and maintenance methods familiar to maintenance personnel
It can directly realize the communication and data exchange between two smart devices without passing through the host, greatly speeding up the data exchange speed and the time for troubleshooting, and can also achieve a one-to-many broadcast mode.
l For equipment manufacturers, our company also provides C2000 serial port bridge for embedded serial device networking server module, which is more compact and can be directly embedded into the equipment. In recent years, with the rapid development of urban construction in China, the original The distribution network and the power supply model have been unable to adapt to the development of the situation and the needs of residents' electricity consumption. In order to meet the user's requirements for power, improve power supply reliability, reduce line losses, reduce the amount of operation and maintenance work, and increase work efficiency and service quality, it is necessary to use various advanced technologies to transform existing distribution networks and equipment, and gradually realize Distribution network automation, in this process, serial device networking server has a wide range of applications.
