The Institute of Electrical Engineering and Technology establishes a mash-up fusion communication system

The "Research and Application of Key Technologies for High-Performance Power Line Carrier-Based Distribution and Communication Networks Based on High-Speed ​​Power Line Carriers" was identified by the Yunnan Science and Technology Awards Office. The experts identified the project as the power carrier communication, power carrier channel noise model, and noise reduction. Other aspects are innovative and the main technologies have reached the international advanced level.

In the course of project research, the Institute of Electrical Engineering and Technology established the first domestic distribution and integration intelligent information and communication system at Haoming Power Company, which realized the unified collection, transmission and application of distribution network operation and marketing information. The system covers 16km 10kV lines and 13 low voltage platforms, and the overall network communication rate reaches 12~78Mbps. It can transmit line fault location, online line monitoring, negative control terminals, distribution terminal, concentrator, video surveillance and other information. And applications. The system has also been applied to other county companies.

The system is based on 200M broadband power line communication network research and development, breaking the key technology of power line communication. The so-called power line communication refers to the signal is loaded on the power line transmission, and then the signal is extracted and applied through a modem. The in-depth development of power line carrier communication channels and research on de-noising algorithms, and improvement and improvement of carrier communication test methods and platforms are important prerequisites for the construction of a carrier-integrated converged communication system. For this reason, the Institute of Electric Power has conducted in-depth studies in five areas. One is the development of power line carrier communication channels and de-noising algorithms. The second is to carry out the simulation test research on the power line carrier communication modulation method, and analyze the error rate of different modulation technologies under different communication rates. The third is to carry out research on reducing interference factors that affect high-speed data transmission in power line carrier communications. The fourth is to build a carrier communication test platform. After the successful construction of the platform, it has completed the test analysis and evaluation of the performance of the 18 factory concentrators, collectors and power meter carrier communication. The fifth is the use of the INTEGRATED INTELLIGENT INTELLIGENT COMMUNICATION SYSTEM developed by the Institute of Electrical Engineering. On the one hand, important information such as 10kV circuit breakers, load switches, transformers, and table data on the Taiwan area can be efficiently transmitted to the substation or the nearest fiber-optic connection in real time. In order to provide the most stable and safest standard data communication for various intelligent devices of 10kV medium voltage distribution network, on the other hand, it can greatly improve the efficiency of meter reading and provide remote power management for power supply enterprises. Two-way network communication platform, so as to easily achieve long-distance electricity pre-paid, automatic power-off and anti-stealing features.

In the course of the project's research, the Institute of Electric Power applied for 9 patents for invention, obtained 2 authorizations, registered 2 software copyrights, participated in the preparation of 2 national standards, and published 11 papers, including 1 EI.
