	发展应用于配电网线路的广域同步测量系统(WAMS)对配电网的安全运行具有重要作用。本文对配电网WAMS功能要求，功耗特性进行了分析，并分别从硬件设计和软件控制策略两方面进行了低功耗设计。针对目前输配电线路同步测量装置供电电源的缺点，提出了一种适用于配电网WAMS在线监测设备的新型供电电源方案。采用取能式电流互感器作为主供电源，锂电池与超级电容器分别作为能量器件和功率器件组成辅助电源。试验测试结果表明：该复合电源可在线路负荷电流低于30 A或断电时向测量装置稳定供电。<br />
The development of wide-area synchronous measurement system (WAMS) for distribution network plays an important role in the safe operation of distribution network. In this paper, the functional requirements and power consumption characteristics of distribution network WAMS are analyzed. The low power consumption design is carried out from two aspects: hardware design and software control strategy. In view of the shortcomings of power supply in WAMS device, a new power supply scheme suitable for distribution network WAMS device is proposed. Current transducer (CT) is used as the main power supply, the lithium battery and the supercapacitor are used as the energy element and power element respectively. The test results show that: the composite power supply can supply stable power to the measuring device when the load current of the line is lower than 30 A or power failure.
