多套低压集抄设备由于存在相互干扰、难以同时进行载波通信性能测试、影响整体测试效率的问题。为此，根据电力线载波通信特点，提出了一种基于频分复用和时分复用的低压集抄设备载波通信批量检测方法，它有效解决了集抄设备间的通信干扰问题，实现多套集抄设备的同时检测，大幅提高载波通信性能检测效率。试验结果表明通过合理制定测试流程，该方法可将集抄设备载波通信测试时间缩减为原来的1/6。批量检测方法已在低压集抄设备测试中得到应用验证，对探索提高低压集抄设备载波测试效率具有一定的借鉴作用。

Due to power line carrier (PLC)communication interference,electric energy data acquisition terminals could not be tested at the same time.So that the testing method is inefficient.This paper proposes a batch testing method of PLC communication for data acquisition terminals based on time division multiplexing and frequency division multiplexing.This method commits to solve the PLC communication interference problem,so that multiple terminals are able to be tested on a testing bench.Experiments has been conducted to validate the method and the efficiecy has been significantly improved.The communication testing time could be reduced to 1/6 at most.The batch testing method which has been applied in Electric Power Research Institute of Guangdong Power Grid Corporation is helpful in improving testing efficiency of PLC communi-cation.
