摘　　要：设计并实现了一套基于无线传输的输电线路调试测量系统.该系统由无线中心主站、无线电流采集传输节点、无线电压采集传输节点组成,采用2.4GHz频段高速无线网桥进行数据通信,以避免变电站常规干扰源的频段,且具有传输距离远、传输稳定的特点.利用互感器套管和电容器组成无线电压采集传输节点,基于霍尔电流传感器和电流互感器组成无线电流采集传输节点.无线电流采集传输节点、无线电压采集传输节点间采用基于IEEE1588协议的时钟同步模块进行时间同步.测量系统实现了数据存储、波形显示、数据分析和报表自动生成等功能.在江苏电网某500kV变电站进行了现场试验,验证了该测量系统的有效性与可靠性.本测量系统可避免复杂的布线工作,减少变电站传导干扰影响,显著提高试验效率.A measurement system for the testing of transmission lines was designed and implemented, which greatly reduced the testing time, avoided the arrangement of cables, and hence enhanced the effi- ciency of the test. The measurement system, consisting of a center station, a current acquisition and trans- mitting node, a voltage acquisition and transmitting node, etc. , is based on wireless communication. A high-speed wireless bridge working at 2.4GHz together with a clock synchronization module based on the IEEE1588 communicating protocol was employed for the communication and time synchronization. The da- ta storage, waveform display, data analysis, automatic report generation and other functions have been achieved in the measurement system. A practical test was done at a 500 kV substation in Jiangsu Province of China, which proves the validity and effectiveness of the measurement system.
