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