摘要
以ZigBee和GPRS通信混合组网方式,实现对10 kV线路沿线的各配变台区用电参数的采集和传输,主要基于ZigBe无线信道为全球无须申请的免费频段,同时考虑台区间因诸多因素无法实现通信链路时,可通过GPRS网络传输数据来解决这一问题,即混合组网。主站对抄回的数据进行理论线损计算并与实际发生的线损进行比对,从中找出问题所在,并通过一个具体实例分析谐波功率对电能计量的影响。
By adopting ZigBee and GPRS communication hybrid network mode the acquisition and transmission of the electricity use parameters from each transformer district along the 10 kV lines were realized. Mainly based on wireless channel ZigBee which is a global free charge frequency zone without petition. Meantime, considering that due to many factors the communication link could not be fulfilled among the transformer districts, the problem could be solved by through GPRS network to transmit data, namely the hybrid network. The main station theoretically calculates the line loss from copied data and compares it with the actual line loss to find out the reason of the problem.
