摘要
随着全国电力联网的进度加快,其调度体系急需完善,配电网自动化的通信问题成为一个难点。主要研究10 kV配电网的自动化通信问题,针对通信条件薄弱地区的配电自动化工程,提出一种依靠电力线作为通信信道的通信解决方案。在研究电力线信道特性的基础上,选用性能良好的扩频码,设计了一种新的通信方案。软件仿真结果显示,该方案可在强噪声信道下进行可靠通信,满足当前配电网自动化工程实际的需要。
With the process of national power network, system of dispatching of power networks must be perfect, the distribution network communication is a nodus. Focusing on 10 kV distribution network communication issue of automation,a communication solution depending on the power line is put forward, aiming at the places whose communication condition is weak. On the basis of studying channel characteristic of the power line,selecting good code for use,a kind of new communication scheme is designed. The emulation results of the software show that the scheme can carry on reliable communication through the strong noisy channel. It meets the needs of distribution network with real automatic project at present.
