电力变电站现行通信方式

为了满足电力系统越来越复杂的通信需求,电力通信已向着网格化、宽带化和综合化的方向发展.论述了电力通信的方式、变电站传输业务的种类和接口及传输设备的接入方式.指出了光纤通信因其通信质量稳定、不易受外界因素干扰、扩容简单、二次投资低等优点而成为现今变电站通信的主流方式;光缆接入的同步数字体系方式具有灵活的组网潜力和强大的维护管理功能成为新一代理想的传输网体制.光纤通信方式可为新的光传输网络的设计借鉴.

Current Communication Mode of Power Substation

To meet the increasing complex communication needs of power system,power communication develops towards gridding,broadband and integration.The power communication modes,the type of power substation transmission services and interfaces as well as the access manners of transmission equipments were discussed.It was indicated that fiber communication has been the main mode of power substation communication because its communication quality was stable,less susceptibly disturbed,and its expansion was simple as well as secondary investment was very low,etc.The synchronous digital system accessed by cable with flexible potential of network organizing and with powerful management functions has become a new ideal transmission network system.Fiber communication could be used for reference of new design of optical transmission network.
