摘要
基于虚拟载波帧测技术的多虚拟逻辑网络组、增强型自适应模拟前端、自适应多频段收发、多耦合方式等关键技术,能够满足不同应用需求。通过新型中压配电线数字载波通信装置(PLC-075)在城市小区配电自动化和中小型水电站信息采集的具体应用案例证明,该装置能够有效和可靠地解决配电自动化系统中压配电线传输特性的动态变化、突发干扰、组网通信和实时性等难题,有着广阔的应用前景。
The key technologies of multiple logic communication networks based on virtual carrier sense mechanism, enhanced adaptive analog front end of receiver, adaptive frequency bands, and coupling means meet various application demands. A novel MV distribution line carrier device (PLC-075) is proposed, and its applications in information acquisition of medium-small hydropower plants and in distribution automation systems of Shanghai urban residential area are illuminated. Applications show that the device can effectively solve the issues of dynamic variations of transmission characteristics, sudden disturbance, group-net communication, and real-timing of MV distribution lines in distribution automation systems.
