摘要
由于配电网点多面广,采用GPS及光纤网络不仅投资大、而且在市政保护、光纤的全面铺设等存在诸多问题。鉴于此,本文提出了一种利用PLC组建配电网时间同步网络的方案,该方案以广播式和请求式相结合的方法,通过解算出网络时间延迟τ,从而得到高精度的配电网系统时间。该方案区别于传统的通信网络模式,不仅组网方便,还可大大降低购置成本。
As more extensive distribution network, the use of GPS and optical fiber and cable networks not only need large investment, but also in municipal protection, the full cable-laying, and so there are many problems. This paper presents a distribution network set up by PLC network time synchronization of the programme. The programme to broadcast on-demand and a combination of methods, calculated through the network of the time delay, so as to get high-precision time distribution network system. The programme is different from the traditional mode of communication networks, that network not only convenient, but also can greatly reduce the purchase cost.
