Intelligent oil-electricity hybrid power system of communication base station

Abstract

The invention discloses an intelligent oil-electricity hybrid power system of a communication base station. The intelligent oil-electricity hybrid power system comprises mains supply, hybrid energy, a hybrid energy manager, a DC / DC (direct current / direct current) conversion controller and a storage battery. The hybrid energy comprises a diesel generating set which is a variable-frequency direct-current generating set, wind energy and solar energy. The mains supply and the hybrid energy are connected with an input end of the hybrid energy manager. An output end of the hybrid energy manager is connected with an input end of the DC / DC conversion controller. An output end of the DC / DC conversion controller is connected with a load. The storage battery is connected with the load and the output end of the DC / DC conversion controller. By the intelligent oil-electricity hybrid power system, seamless switching between the variable-frequency direct-current generating set and renewable energy is realized, the renewable energy can be fully utilized while atmospheric pollution can be reduced, and great significance for human environment protection is achieved.

Description

technical field [0001] The invention relates to an intelligent oil-electric hybrid power supply system for a communication base station Background technique [0002] At present, base stations without mains electricity generally use diesel generators for power supply. In the Middle East, North Africa, Southeast Asia and western my country, more than 100,000 base stations are powered by diesel generators. These base stations are usually powered by two diesel generators in turn. The traditional way of supplying power to a base station without mains electricity consists of two diesel generator sets 11, 12, an automatic switching device (ATS) 20, a storage battery 30 and a DC voltage control cabinet 40 (such as figure 1 shown). The automatic switching device 20 controls the two diesel generating sets 11 and 12 to charge the storage battery 30 alternately. When this kind of traditional diesel generator set is used in the communication base station, due to the long-term low loa...

Problems solved by technology

However, the uncertainty of wind resources and the discontinuity of solar energy lead to pulsating and discontinuous power output from wind generators and solar panels, which cannot be directly used for people's production and living electricity needs without control

Therefore, these new energy sources need to be equipped with a separate controller to be connected to the hybrid energy system, which is expensive
