Problems solved by technology

[0005] There are many shortcomings in the centralized control system currently used for aircraft power generation, among which there are three main shortcomings: 1. Reduced reliability
The full authority digital electronic controller (FADEC) in the control system not only needs to realize all the main functions such as signal acquisition, processing, control calculation and control signal output, but also realizes the functions of status monitoring, fault detection and safety protection, which makes FADEC The software in the computer is huge and complex, and the computer load is heavy, resulting in a decrease in real-time performance. Once the computer fails, the entire system cannot work
Second, it is not conducive to the expansion of the control system
Three, not conducive to maintenance

Abstract

The invention discloses an aeroengine generating system. An aeroengine generating set comprises an electric motor / exciter which is coaxially connected with a generator and an aircraft in the aeroengine power generating set; an aeroengine generating control system comprises a main controller, a starting excitation controller and a fuel adjusting controller which form a distributed bus control network in a mode of a bus; each controller is an independent node on the bus; and the main controller is a main node, and the fuel adjusting controller and the starting excitation controller are slave nodes. Each control part is designed in a modularizing mode and controlled in a distributed mode, so that the individual and general safe, economic, stable and reliable operation is realized in the aeroengine generating system, and the aeroengine generating set has the advantages of fast starting, smooth transition, high control precision, simple operation, strong adaptability and high reliability. Compared with a centralized control system in the prior art, each controller has the control function, and a universal standard device can be adopted, so that the aeroengine generating system is easy to expand and the maintenance cost is greatly reduced.

Description

technical field [0001] The invention relates to a power generation system, in particular to an aircraft power generation system using an aeroengine as the driving power of a generator. Background technique [0002] The aircraft power generation system is a high-efficiency, energy-saving and environmentally friendly power generation device that adapts the aeroengine (aircraft for short) to power generation on the ground after a series of modifications, including the aircraft generator set and the aircraft power generation control system. Among them, the aircraft The power generation control system is an integrated control system that takes aircraft generator sets as the object and involves control, computer, communication, power, electric power and many other disciplines. It is one of the key technologies and an important part of aircraft power generation. [0003] The development of aircraft power generation control technology has gone through stages of hydraulic mechanical ...
