Abstract

The invention discloses a frequency-conversion energy-saving diesel generator set of a communication base station. The output power of the frequency-conversion energy-saving diesel generator set is changed along with power required by a load, wherein the frequency-conversion energy-saving diesel generator set comprises a diesel engine, a permanent magnet generator, an AC / DC (Alternating-Current / Direct-Current) converter and an accelerator controller; the diesel engine is provided with an accelerator executor; the diesel engine is mechanically connected with the permanent magnet generator to transmit mechanical energy to the permanent magnet generator, so that the permanent magnet generator converts the mechanical energy into electrical energy; the AC / DC converter is electrically connected with the output end of the permanent magnet generator; the AC / DC converter converts AC output by the permanent magnet generator into steady DC and provides the DC for the load; the accelerator controller is electrically connected between the output end of the AC / DC converter and the accelerator executor of the diesel engine; and the accelerator controller outputs a control signal to the accelerator executor of the diesel engine according to the load current, so that the rotation speed of the diesel engine is adjusted.

Description

technical field [0001] The invention relates to a frequency conversion energy-saving diesel generator set for a communication base station, which is mainly used for power supply of communication base stations and military field equipment. Background technique [0002] As the main power supply configuration of the communication base station, the diesel generator set plays an important role in the safe operation of the communication base station. For some communication base stations without mains power supply, they generally rely on batteries and diesel generators for power supply. The best combination is that the generator and the storage battery supply power in turn, and the working mode is: the generating capacity of the generator set must be the sum of the power consumption of the load and the charging power of the storage battery. After the battery is fully charged, the generator is disconnected, and the battery supplies power to the load. When the battery discharges to...
