基于DXC的变电站语音通信接入方式优化

针对目前宁夏电网变电站语音通信接入方式中存在的瓶颈问题,分析了传统脉冲编码调制(pulse code modulation,PCM)技术对电力通信网发展的影响,结合宁夏电网变电站语音通信业务接入需求及 PCM 设备配置情况,提出基于数字交叉连接设备 (digital cross connectequipment,DXC)语音复接设备的优化业务接入方案。应用结果表明:该方案有效解决了机房空间资源需求大、组网方式单一、业务扩展能力差、不便于维护等问题,具有投资少、收效明显、工程量小、便于实施等特点。

Optimization of substation voice communication access mode based on digital cross connect equipment

Aiming at the existing bottleneck problems of substation voice communication accessmode in Ningxia power grid,analyzes the influence of traditional pulse code modulation (PCM ) technology on the power communication development. Combining with the access demand ofsubstation voice communication operation and PCM equipment configuration of Ningxia power grid,based on digital cross connect equipment (DXC)and voice mutiplex equipment puts forward theaccess optimization scheme of using voice multiplex equipment. The application result shows thatthe scheme effectively solve the problems of small space of computer room,single network mode, service expansion insufficient and inconvenient maintenance,and has the characteristics of lessinvestment,obvious achievement,small project volume and convenient implementation.
