Research Of The PFTTH Key Technology And Operation Mode

With the unceasing change of world politics and economy environment state grid corporation will face more severe test, both energy and to guarantee the quality of electricity services. To solve these problems in order to state grid corporation launched the smart grid, power grid and the user can real-time interaction between response is the smart grid is an important embodiment. Electric power fiber to the home can be very good to strengthen the ability of power grid as a whole, improve service quality, strengthen the purpose of real-time interaction.This article first from the dynamic of power fiber to the home in the domestic and foreign development, the research significance and so on are expounded; Secondly, starting from the key technology of electric power optical fiber to the home, including Ethernet passive optical network technology and optical fiber composite low voltage cables. Studied the Ethernet passive optical network mode, network, network topology design, analyzes the four types of Ethernet passive optical network system redundancy protection scheme, as well as the network topology design at the design of light series and spectral ratio; Analyzing technology of optical fiber composite low voltage cables, illustrates the optical fiber composite low voltage cables and Ethernet passive optical network technology application in the construction of rationality, finally realizes the power fiber to the home; Again, the research electric power fiber to the home network structure design, including power fiber to the home of the whole structure, the communication network, the technical route and the north in the spring area electric power fiber to the home design puts forward solutions to achieve the optical fiber to the home, electricity information collection, intelligent multifunctional interactive terminal operations; Finally, in view of the electric power fiber to the home business model to carry on the design analysis, including the operating model and business model for electric power fiber to the home operation mode analysis, and combined with hebei electric power optical fiber to the home to verify operation analysis.The electric power optical fiber to the home access network design by using Ethernet passive optical network technology at the same time in the village between transformer room and distribution room building using optical fiber composite low voltage cable as transmission channel. Electric power fiber to the home will be divided into two kinds of structure design for building structure difference design structure, mainly manifested in the choice of optical fiber to the home access points and the selection of electricity information collection access point two aspects. Design is completed through cable droop calculation the network mode can meet the requirements to implement. According to the analysis of electric power optical fiber to the home business system research concludes three possible power optical fiber to the home of the operation mode includes:build proprietary, build the jv, & the joint venture. Three operating modes have different advantages and disadvantages, the project owner can according to different local environment and their own characteristics to choose a pattern or a combination of several patterns for the operations of power fiber to the home. Combined with hebei electric power fiber to the home operations to verify the feasibility of three kinds of operation mode andeventually achievecostrecoveryandgenerate economic benefits.
