基于EPON和工业以太网的新型配网通信混合组网方案

A New Hybrid Communication Network Scheme for Distribution Networks Based on EPON and Industrial Ethernet

介绍了以太网无源光网络(EPON)技术和工业以太网技术原理,对这2种通信组网方案进行了经济技术对比,在此基础上提出了基于EPON和工业以太网的新型配网通信混合组网方案。该方案在系统的可靠性、扩展性、接入便捷性、兼容性等方面均有优越性能,适应实际工作环境能力更强,并通过工程实例进行了验证。

Communication network plays a crucial role in the development of a first-class power distribution network. This paper introduced in details the principles of Ethernet passive optical network （EPON） and industrial Ethernet technology, and then analyzed EPON network scheme and industrial Ethernet network schemes. By comparing the two network technologies, this paper highlighted the characters and deficiency of the two network schemes if they are used in individual. Based on the comparison, a new hybrid communication network scheme for distribution networks based on EPON and industrial Ethernet is proposed. The scheme has better performances in terms of reliability, extensibility, access convenience, compatibility and ability to adapt to the practical situations. At last, an example of the engineering practice of the proposed network scheme in Suzhou Power Supply Company is introduced.
