摘　　要：针对目前电能质量监测数据采用专用有线网络方式传输存在的接入终端范围受制约、网络带宽资源受限、建设维护投入大且周期长等问题,研究并实现了基于3G技术的电能质量监测系统无线通信网络。提出了无线通信网络硬件架构,采用L2TP与IPSec相结合的VPN技术构建监测数据虚拟专用传输通道。通过对试运行期间实测数据传输速率、网络稳定性及抗攻击能力进行分析,证明了该方案具有较高的可靠性、安全性及工程实用价值。目前3G无线网络作为有线网络的重要补充,已经在四川电网统一电能质量监测系统中成功应用。At present, the dedicated wired network transmission mode used to transfer power quality monitoring data has some shortcomings, for example, the accessing terminals scope and the bandwidth resources are constrained, the investment of construction and maintenance is large and the period is long, and so on. To deal with them, this paper proposes a 3G-based power quality monitoring system wireless communication network. The hardware architecture of wireless communication network is proposed and the VPN technology based on the L2TP and IPSec combination is used to build a virtual private monitoring data transmission channel Through analyzing the measured data transmission rate, network stability and anti-attack capability during the test run, the high reliability, security and practical value of this solution are proved. Currently the 3G wireless networks is successfully applied in Sichuan power grid unified power quality monitoring system as an important supplement to the wired network.
