Operation principle of wind-solar hybrid communication base station

Wind-solar hybrid power system based on the wind energy and solar energy is an ideal and clean solution for the power supply of communication base station，especially for those located at remote areas such as islands.The hybrid power system provides reliable power supply while reducing the initial investment，the maintenance costs and carbon emission.A practical and reliable designing scheme of wind-solar hybrid power technical solution was presented and analyzed for a communication base station in a remote island.

High frequency inverter front stage output

The high-voltage output generated by the front-stage transformer passes through the high-frequency transformer to output high-frequency alternating current, and then a high-frequency hundreds of V direct current is output to the back-stage mosfet/IGBT through the fast recovery diode full bridge rectification, and then the back-stage IC generates 50Hz control signal which is used to control the work of the mosfet/IGBT of the subsequent stage, and then output 120v/ 220v/ 230v/ 240v V 50/60Hz alternating current.

Wind power hybrid energy storage device

Hybrid energy storage, with its high power density, energy density, and long lifespan, has become a crucial support for grid-connected wind power systems. 5 Energy-based storage (e.g., batteries and hydrogen) is effective for smoothing long-term power fluctuations, while power-based storage (e.g., supercapacitors and flywheels) responds quickly to transient fluctuations.
