Electric power wireless broadband communication system based on TD-LTE 230

Abstract

The invention provides an electric power wireless broadband communication system based on TD-LTE 230 by combining the actual service requirements of a power distribution and consumption network of an intelligent power grid and the existing spectrum resources of power enterprises. The system comprises a core network, a network management system, a base station, a communication terminal and other network element equipment. The invention further provides a networking network for the network element equipment. The system involves the spectrum sensing and carrier aggregation technology under a discrete and narrow-band spectrum condition, the link adaptive algorithm, the enhanced interference suppression technology, the power control technology, the automatic matching algorithm for downlink and uplink bandwidth and other advanced technologies, provides a solution for the problem that the existing electric power system is low in spectral efficiency, low in networking capability and poor in real-time performance, and can realize reliable communication among a large number of scattered nodes of a power distribution and consumption system. The system provided by the invention supports electric information acquisition, distribution network automation, load control monitoring, video surveillance and other services in the power distribution and consumption link.

Description

technical field [0001] The invention relates to the technical field of power system communication, in particular to a TD-LTE 230MHz-based power wireless broadband communication system. Background technique [0002] Smart grid is the latest trend in the development and transformation of power systems in the world today, and is considered to be a major technological innovation and development trend of power systems in the 21st century. In the construction of smart grids at home and abroad, smart power distribution networks and smart power consumption networks are very important components of smart grids. In terms of wireless communication for power distribution, my country mainly uses public network communication (GPRS, CDMA, etc.), 230MHz digital radio private network, etc., which have disadvantages such as low transmission rate, weak networking ability, poor real-time performance, and poor security and reliability. Although some power companies are also trying to introduce ...

AI Technical Summary
