A communication base station photoelectric complementary power supply system and its operation method

Abstract

The invention relates to a communication base station solar complementary power supply system and an operation method thereof. The system can be applied to the purposes of a communication base station power supply, a household power supply system, a village level solar photovoltaic power station and the like. Compared with a traditional power supply system, the investment and equipment energy consumption can be saved. The system is formed by a solar photovoltaic component, a solar controller, an Emerson switch power supply, an Emerson photoelectric complementary controller, a Chery lithium battery group, a battery management system (BMS), and a Chery remote diagnosis device. The system is a set of intelligent power control system which is based on the technology of the lithium battery, the battery management system, the photovoltaic grid-connected power generation, the remote diagnosis and the like and is developed with the combination of solar component development, and the solar complementary power supply system is suitable for the purposes of the communication base station power supply, the household power supply system, the village level solar photovoltaic power station and the like.

Description

technical field [0001] The invention relates to the field of new energy and power electronics, and in particular to a photoelectric complementary power supply system for a communication base station and an operation method thereof. Background technique [0002] At present, the backup power sources of the base stations of various communication operators mainly include: lead-acid battery packs, lead-acid battery packs + diesel generator sets; the main source of power for the load is the mains power, and the diesel generator sets and batteries are only used in emergencies such as grid power outages. The base station provides electrical energy. Moreover, the above backup power system has the following disadvantages: [0003] 1. The lead-acid battery is large in size, the electric energy storage is small, and the system occupies a large area; [0004] 2. Diesel power generation is noisy, causing serious air and base station environmental pollution; [0005] 3. The cost of dies...
