The main systems of the communication power station include
In reality, a base station consists of several subsystems that must work together: the antenna-feeder system, the radio frequency unit, the baseband unit, and supporting infrastructure such as the tower, equipment room, power supply, and air conditioning. The power system is a power production and consumption system involving power generation, transmission, transformation, distribution, and consumption. It generates electricity from primary energy sources and delivers it to users through power transmission, transformation, and distribution. In this post, we will discuss the majority of current communication systems that are useful for providing accurate and precise control over the operation of the power system. It applies to greenfield sites and major augmentations. In order to integrate substation protection, control, measurement and monitoring applications into one common protocol, a new communication protocol has been developed and standardized as IEC 61850 – Communication Networks and Systems in Substations. Base stations are the foundational elements that make this connectivity possible, acting.
