摘　　要：基于Zigbee的空间电荷密度无线网络测量系统被广泛应用于特高压直流输电工程的空间电荷密度测量。实际使用中,无线测量系统的功耗问题成为制约设备工作性能的关键因素。该文针对空间电荷密度测量系统中无线通讯单元的分布特点,研究了无线通讯单元的低功耗工作状态转换机制和发射功率匹配方案和通讯距离及工作环境对功耗的影响。最终制定了低功耗能量管理策略,有效提高了空间电荷密度测量系统的工作性能。Zigbee-based space charge density measurement system is widely used in space charge densitymeasurements of high voltage direct current （HVDC） transmission project. In practice, the power consumption ofthe space charge density measurement system is a key constraint of the device performance. According to thedistribution characteristics of wireless communication unit of space charge density measurement system, thelow-power operation status transition mechanism and the influence of communication distance and workingenvironment on power consumption are analyzed. At the end, the low-power energy management strategy isdeveloped. The proposed strategy effectively improves the performance of space charge density measurementsystem.
