Problems solved by technology
[0003] In the prior art, when powering a communication base station, the engine needs to continue to work at a fixed frequency, generally 50 Hz or 60 Hz; during the operation of the engine, the temperature of the engine will rise; The working engine will cause overheating. As a protective measure, the engine will stop working to avoid damage to the engine or the communication base station; The mobile terminal that transmits communication signals through the communication base station cannot work normally

Embodiment Construction
[0020] The method, device and system for adjusting the output frequency of the generator set according to the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0021] It should be clear that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] For the communication base station erected outdoors as a load, it is necessary to set up a generator set to supply power for the communication base station with a fixed output frequency. In China, the output frequency is generally divided into the first output frequency and the second output frequency, of which the first output frequency When outputting, the output frequency of the alternating current is ...

The invention discloses a generator set output frequency regulation method, a device and a generator set, and belongs to the field of power supply and distribution. The method, the device and the generator set are designed for solving the problem that the generator stops working due to the motor which is overhot during long-time operation in the prior art, and reducing the working reliability of a load powered by the motor. The generator set output frequency regulation method comprises the following steps of: obtaining a control parameter value of the motor; when the control parameter value exceeds a preset threshold, breaking the connection of the motor in the generator and the load; and shifting the motor in the generator from a first rotation speed to a second rotation speed, so that the output frequency of the generator can be shifted from a first output frequency to a second output frequency.
Description
technical field [0001] The invention relates to the field of power supply and distribution, in particular to a method and a device for adjusting the output frequency of a generator set and the generator set. Background technique [0002] With the development of communication technology, mobile communication has gradually become an indispensable main communication channel in work and life, so the coverage of communication signals is gradually extended. Communication base stations used for communication signal transmission also cover various places. When the communication base station is working, it is powered by the alternating current transmitted by the public grid. However, due to the geographical environment, sometimes it is difficult to supply power through the public grid for the outdoor communication base station. At this time, the communication base station will be powered by a generator set. [0003] In the prior art, when powering a communication base station, the e...
