Abstract

The invention relates to an electric power wireless private network-assisted transmission method and system. The electric power wireless private network-assisted transmission method comprises the following steps that in an electric power wireless private network, a baseband processing unit affiliation variable matrix A(B,U) is set according to the transmission states between baseband processing units and wireless terminals, and a radio frequency unit affiliation variable matrix T(K,U) is set according to the transceiving states of radio frequency units, wherein B represents the baseband processing unit number, U represents the wireless terminal number, and K represents the radio frequency unit number; a channel state matrix H(K,U) from the radio frequency units to the wireless terminals and a precoding matrix W(K,U) from the radio frequency units to the wireless terminals are set; a power function and a limitation function of the electric power wireless private network are set according to the A(B,U), the T(K,U), the H(K,U) and the W(K,U); transmission parameters enabling the power function to be minimum are calculated according to the limitation function, and target transmission parameters are obtained; the electric power wireless private network is controlled to conduct data transmission according to the target transmission parameters; accordingly, higher handling capacity of an electric power wireless private network transmission system can be achieved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and system for assisted transmission of electric power wireless private network. Background technique [0002] With the increasing demand for communication coverage of power distribution services such as distribution network automation, metering automation, and video surveillance, the problems of traditional optical fiber, carrier and other wired communication technologies such as difficult deployment, long construction period, and difficult topology change have become difficult. In order to meet the current situation that the demand for power distribution and communication is multifaceted and wide, it is urgent to use wireless communication technology for fast and efficient coverage supplementation. At present, the power industry is widely deploying the power wireless private network based on the TD-LTE communication system to effectively carry production servic...
