基于HPLC双模通信在台区组网的技术应用研究

Research on the Application of Networking Technology Based on HPLC Dual-mode Communication

在电力系统通信组网中,台区组网作为其中重要一环,主要是智能融合终端和各类配电智能设备间的互联互通。HPLC高速载波通信对台区改动小且可应用范围广,故作为台区组网首选的通信方式。而台区中部分业务设备及传感器由电池供电,无法使用电力线载波技术进行通信,所以在HPLC技术的基础上引入了更适合该工作模式的微功率无线通信技术。在这个系统中,融合终端集中处理整个台区数据,需要支持与HPLC和无线等各种不同通信类型的智能设备通信。为此,提出一种基于HPLC与微功率无线相结合的双模通信混合组网方案应用于台区设备的网络通信中,这种组网技术方案除了能够应对台区组网中多种不同通信的要求,既具备HPLC技术长距离通信特性,又弥补了中短距离通信方面的不足,还可以应用在一些实时性不高、数据量不大的特殊场景,使得电力本地通信业务充分利用专网及无线网资源,兼顾了通信方式的灵活应用,更加适应台区组网通信需求,可以为建设一张具有决策权的台区通信网络提供技术基础。

In the power system communication network,the station network is an important part,which is mainly the interconnection between the intelligent fusion terminal and various kinds of intelligent distribution equipment.HPLC high-speed carrier communication has little changes to the station area and can be applied in a wide range,so it is assumed to be the preferred communication mode for the station area network.However,some business equipment and sensors in the station area are battery-powered and cannot use power line carrier technology for communication.Therefore,micro-power wireless communication technology which is more suitable for this working mode is introduced on the basis of HPLC technology.In this system,the converged terminal centrally processes the entire station data and needs to support communication with various types of intelligent devices such as HPLC and wireless.Therefore,a hybrid networking scheme based on dual-mode communication combined with HPLC and micro-power wireless is proposed,which is applied to the network communication of equipment in the station area.This networking technology scheme can not only meet the requirements of a variety of different communications in the station area networking,but also has the characteristics of HPLC technology for long-distance communication,and makes up for the shortcomings of short and medium distance communication.It can also be used in some special scenarios with low real-time performance and small data volume,so that the power local communication service makes full use of private network and wireless network resources,takes into account the flexible application of communication methods,and is more suitable for the communication needs of the station network,which can provide a technical basis for the construction of a station communication network with decision-making rights.
