Abstract

The invention relates to a wind-photovoltaic-diesel-battery independent power supply coordinated control system for communication base stations. The system comprises a wind-driven generator, a photovoltaic generation array, a battery pack, a diesel generator set, a communication base station load, a micro-grid monitoring system, a digital signal processor, an AC load, and a controllable load. The power output end of the wind-driven generator is connected with the AC power input end of a first AC/DC converter. The DC power output end of the first AC/DC converter is connected with the input end of a first DC/DC converter. The power output end of the photovoltaic generation array is connected with the input end of a second DC/DC converter. The power output end of the diesel generator set is connected with the AC power input end of a second AC/DC converter. In view of random and intermittent natural resources and the change of the communication base station load, the demand for continuous and stable power supply to a communication base station is satisfied through coordinated control on a wind-solar generation unit, an energy storage device and a diesel.

Description

Technical field [0001] The invention relates to the technical field of DC microgrid systems, in particular to a coordinated control system and method for independent power sources of wind and diesel storage for communication base stations. Background technique [0002] With the popularization of mobile phones, the requirements for the coverage of mobile signals have become more and more extensive, and the construction of communication base stations has gradually spread from urban centers to remote areas. In some remote areas, it is difficult to access city electricity due to geographical restrictions. Usually we choose to use the abundant local resources such as wind and solar to generate complementary power. Since the power generation of natural resources such as wind and wind is greatly affected by climate and season, it is necessary to add energy storage device batteries to stabilize the entire system. When the battery fails or encounters continuous rainy days, the wind and s...
