[0040] In the first embodiment of the present invention, a method for controlling a generating set includes the following specific steps:

[0041] Step S101, when it is detected that any group of mains transformers cannot output mains power normally, or when an instruction to start the generator set is received, start the air intake roller shutter, the exhaust device and the air inlet axial flow fan in the generator set in sequence; When the air intake roller shutter, exhaust device and air intake axial flow fan are all working normally, start all the generators in the generator set at the same time after the first period of time, and output the mains power through the generator set instead of the mains transformer of this group .

[0042] In this embodiment, any group of commercial power transformers cannot output commercial power normally, including at least one of the following:

[0043] Any group of mains transformers cannot output mains power;

Abstract

The invention proposes a control method for a generating set, which includes: when it is detected that any group of commercial power transformers cannot output commercial power normally, or when an instruction to start the generating set is received, sequentially start the air intake roller shutters and exhaust air in the generating set; device and the air inlet axial flow fan; when it is detected that the air inlet roller shutter, the exhaust device and the air inlet axial flow fan are all working normally, start the generator set at the same time after the first length of time All the generators in the system, and output the mains power through the generator set instead of any set of mains transformers. The invention also discloses a generator set control system. By implementing the above scheme, auxiliary equipment such as air intake roller shutters, exhaust devices, and air inlet axial flow fans in the generator set can be effectively and automatically connected with the generator to realize the control system of the generator set. Fully automated control.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to a method and system for controlling generator sets. Background technique [0002] The safe and stable operation of the generator not only requires high reliability, but also puts forward the same reliability requirements for the auxiliary equipment of the generator, especially for the key auxiliary equipment such as air intake, exhaust and smoke exhaust. . Failure of any auxiliary equipment may cause the generator to fail to work or malfunction, and even cause safety production accidents. Most of the existing generator controllers monitor the parameters such as the rotating speed, oil pressure, and frequency of the generator, and cannot effectively monitor and control the operating status of auxiliary equipment, especially in the machine room that requires high automatic operation of the generator. , it is particularly important for effective automatic connection and logic p...
