Why should communication base stations install smart power?

2. Fine management

Intelligent power supply can realize the fine management of the input and output of the power supply, accurately distribute power according to the priority and power requirements of various equipment at the base station, such as communication equipment and air conditioning equipment, and reasonably distribute power. For instance, it is necessary to give priority to guaranteeing the power consumption of communication equipment when the main electricity cannot be sufficiently supplied. In addition, limiting the power consumption of other assistant equipment, like an air conditioner, is needed to avoid the occurrence of a power outage for crucial communication equipment caused by inappropriate distribution.

Meanwhile, the intelligent power system can perform intelligent charge and discharge management of the battery, which can automatically adjust the charging current and voltage according to the type, status, and service life of the battery and other factors so as to extend the service life of the battery. Such as for lead-acid batteries and lithium batteries, smart power supplies will adopt different charging strategies to avoid overcharging and over-discharging of batteries.

3. Recording and analysis of data

The smart power system will record a large amount of power data, including historical voltage fluctuations, battery charge, and discharge times and depth. These can provide a basis for the maintenance and optimization of base station power. For instance, through long-term data analysis, it is found that the mains voltage of a certain base station is often too high or too low, and targeted measures can be taken, such as installing a regulator.

– Data analysis can also be used to predict power failures. By analyzing the change trend of power parameters, such as the gradual increase of battery internal resistance, you can detect potential faults in advance, so that you can maintain or replace components in advance, and reduce the risk of communication interruption caused by power failures in base stations.

Second, improve power reliability

1. Redundant backup and switchover

– Redundancy is usually considered when it comes to the design of smart power systems. This can be illustrated by an instance wherein two or multiple power inputs are used: automatically switching the system to another power supply when one fails–to the backup generator or UPS power supply, for example. This fast switching function will enable the base station equipment with uninterruptible power, and the general time to switch can be at millisecond levels to avoid shutting down communication equipment because of power failure in an instant; thus, the stability of communication can be ensured.

While simultaneously watching the backup power supply’s real-time status in real-time, such as in battery packs. Automatically starts up the backup power in case of failure of the main feed, shifts the load power onto the backup feed accordingly, and sends timely fault notices to maintenance staff.

2. Fault diagnosis, self-repair

It integrates the function of fault diagnosis into the intelligent power supply. In case the power supply fails, it will soon locate the place of the fault, either the fault of a power module, battery, or other lines. For instance, by the built-in diagnostic algorithm, one can determine if a particular capacitor is broken down or a specific fault condition has occurred, like the fuse blowing.

Some minor failures can be self-healing for the smart power system. For instance, when it detects that a power module is overloaded, it can automatically adjust the working state of the module or enable the standby module to restore the normal operation of the power system and reduce the downtime of the base station caused by a power failure.

Third, adapt to the requirements of green energy saving

The design optimizations include: 1. Energy efficiency optimization: Through this, the smart power can optimize the conversion efficiency of the power supply. Accordingly, the working mode will be automatically adjusted according to different magnitude, so that the power source supplies with a high conversion rate for various types of load states. For instance, when the power consumption of the base station equipment is low at night, the intelligent power supply can automatically switch to the low power consumption mode to reduce its own energy consumption.

The intelligent power system can also save energy for the equipment in the base station. For example, by connecting with the intelligent air conditioning system in the base station, the operating power of the air conditioner is automatically adjusted according to the temperature of the equipment room, so as to avoid excessive cooling or heating of the air conditioner, thereby reducing the overall energy consumption of the base station.

2. Access management of New energy

Since new energies access more and more into the communication base stations, intelligent power would take effect for access management of these accesses effectively. For example, intelligent power supply in base stations installed with solar photovoltaic power generation systems carries out intelligent management for electric energy generated by solar panels through charging control, energy storage (such as battery charging), and collaborative power supply with mains, etc., which elevates the proportion of new energy in base station power supplies, reduces the reliance on traditional mains, and finally accomplishes green communication.
