摘要
从杆架式变压器收集的电压、电流和温度测量值通过蜂窝移动技术传送到远程监控。由于蜂窝移动技术的高成本,电能质量监测过程中受到诸多限制且数据采集间隔较长。为了缓解这些问题,文中提出了一种有线中继子系统和无线采集子系统组合的通信基础设施,变电站和监控中心之间进行有线连接,杆架式变压器和变电站之间进行无线连接,实现了成本降低并提供可靠的数据传输。在无线连接方面,采用了无线传感器网络并设计基于树的数据转发协议来定制电能质量信息分布模式从而提高数据传输的质量。通过NS-2网络模拟器定量地验证了所提出的数据转发协议的性能。
The voltage,current and temperature measurements collected from pole-mounted transformers are transmitted to remote monitoring via cellular mobile technology.Due to the high cost of cellular mobile technology,there are many limitations in the process of power quality monitoring,and the data acquisition interval is long.In order to alleviate these problems,a communication infrastructure composed of wired repeater subsystem and wireless acquisition subsystem are proposed in this paper.Wired connection is made between substation and monitoring center,and wireless connection is made between pole-mounted transformer and substation.The cost is reduced,and reliable data transmission is provided.In the aspect of wireless connection,wireless sensor network is used and a tree based data forwarding protocol is designed to customize the power quality information distribution mode to improve the quality of data transmission.The performance of the proposed data forwarding protocol is verified quantitatively by NS-2 network simulator.
