Control method of ATS control cabinet of diesel power generation power assembly

Abstract

The invention discloses a control method of an ATS control cabinet of diesel power generation power assemblies. The ATS control cabinet is electrically connected with the multiple diesel power generation power assemblies and a commercial power grid. The control method of the ATS control cabinet of the diesel power generation power assembly comprises the steps that S1, the ATS control cabinet detects whether a mains supply grid breaks down or not in real time; S2, when the commercial power grid breaks down, the ATS control cabinet switches the load to the diesel power generation power assembly, and power supply is prepared; S3, the ATS control cabinet automatically inputs the diesel generator power assemblies with the corresponding number according to the capacity increasing requirement, so that the diesel generator power assemblies are connected in parallel; S4, after the fault of the commercial power grid is recovered, the ATS control cabinet disconnects the plurality of diesel generator power assemblies and shuts down the diesel generator power assemblies, and the ATS control cabinet enters a next automatic starting preparation state. According to the control method of the ATS control cabinet of the diesel power generation power assembly, a plurality of diesel power generation power assemblies can be connected in a grid-connected mode according to load requirements, and therefore, normal public power supply can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of diesel generators, in particular to a control method for an ATS control cabinet of a diesel generator power assembly. Background technique [0002] Diesel powertrain is a diesel generator set, which is a kind of power equipment that uses a diesel engine as a prime mover and drives a synchronous generator to generate electricity. At present, when the mains power grid is in use, failures or power outages often occur due to excessive loads, and the existing technology lacks a control cabinet that can quickly, automatically and stably switch between mains power and engine power generation, and cannot switch multiple The engines are connected to the grid, so that the normal power supply to the public cannot be guaranteed. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowl...
