With the increase of power density and voltage drops on the power transmission line in macro base, it is recommended to use HVDC system for the 5G network. Requirements to ICT equipment Power Supply Unit (PSU) and supporting facilities. -42V. It means that if the voltage drop is more than 6V, the ICT equipment will be protected.
The power supply equipment manages the distribution and conversion of electrical energy among equipment within the 5G base station. During main power failures, the energy storage device provides emergency power for the communication equipment.
During main power failures, the energy storage device provides emergency power for the communication equipment. A set of 5G base station main communication equipment is generally composed of a baseband BBU unit and multiple RF AAU units. Equation 1 serves as the base station load model:
At the same time, the new equipment has altered the power load characteristics of base stations. In the 5G technology framework, the 5G base station comprises macro and micro variants. The micro base station serves indoor blind spots with minimal power consumption. The macro base station exhibits greater potential for demand response.
