1引言

随着经济的发展,科技的进步,人们的生产和生活对电能质量要求不断提高的同时,越来越多新设备的投入导致电网发生变动,产生了许多电能质量的问题,对电网的实时监测和管理提出了更高更复杂的要求。必须对全电网进行实时动态的监测,保证系统可靠稳定的运行和高质量供电,必须对全电网进行实时动态的监测[2]。目前对电网电能质量监测传输的方式都为有线传输,传统的有线监测手段存在着布线困难、难以调整以及安装、维护成本高等缺点。因此造成了调试、维护等工作量大、灵活性差、设备的自动化技术水平较低。同时电能质量的数据量较大,对传输系统的传输速率和实时性要求更加苛刻。在保证传输速率以及克服有线传输不足的前提下,提出了一种基于无线的高速传输技术,对电网进行实时的监测,既保证数据的有效传输,又能弥补有线带来的不便。……
