电力调度系统使用的几种备用通道技术及比较

介绍了电力调度系统常用的几种通道技术,并着重描述了一种利用无线商用网络进行实时数据传输的通道技术。该技术适用于末端变电站、小型火力发电厂、箱式变电站等分散小数据量传输点的通道建设,同时可以作为具有光纤通道的变电站、发电厂的备用通道。通过对通道的实现方式和优缺点的介绍和比较,为大家选用适合于自己的通道方式提供参考。

Several Techniques of Backup Channel Used by Electric Power Dispatching System and Their Comparisons

Several techniques of communication channel often used in electric power dispatching system are discussed.The emphasis is put on a system which realizes the real-time data transmission through wireless commercial communication network.This technique can be applied to the communication channel with scattered spots such as terminal substation,small-scale thermal power plant and cubicle-type substation etc.,where only small quantity of data needs to be transmitted.It can also serve as the backup channel for substation and power plant which have the optical fibre channel.By analyzing the advantages and disadvantages of different channel techniques,it can be a reference in channel design.
