What are the functions of wind power protection boxes in communication base stations

Protection schemes within these types of equipment are designed by their manufacturers and are integral to the equipment. Wind Electric Plants are composed of many wind turbine generators (WTGs) which are connected to a collector substation through a collector system.

Worldwide thousands of base stations provide relaying mobile phone signals. Every off-grid base station has a diesel generator up to 4 kW to provide electricity for the electronic equipment involved. The presentation will give attention to the requirements on using windenergy as an energy source for powering mobile phone base stations.

Power Supply: The power source provides the electrical energy to base station elements. It often features auxiliary power supply mechanisms that guarantee operation in case of lost or interrupted electricity, during blackouts. Baseband Processor: The baseband processor is responsible for the processing of the digital signals.

As the incessant demand for wireless communication grows, off-grid telecommunication base station sites continue to be introduced around the globe. In rural or remote areas, where power from the grid is unavailable or unreliable, these cell sites require generator sets to provide power security as prime power or backup standby power.

Ideally, the protection scheme applied at the main feeder breaker at a WEP station provides primary protection for the collector feeder and backup protection for the step-up transformer at each WTG location.

It is important to consider applicable regulatory requirements, such as low-voltage ride through (LVRT), to enable the wind power plant to assist the grid during contingencies. Maintaining adequate power quality is another such consideration.
