Analysis&Research Of One Airborne Power Generating System

There are kinds of loads in airborne elctrical system.Those loads such as electrical powersteering gears has serios impact on the power supply system when they work and may causeserious system disturbance,In this condition,rapid closed-loop dynamic response and highstability of power generating system is demanded.With the development of system simulationtechnology, by establishing the system mathematical model, using simulation tools to optimizesystem design and technical parameters, high stability of the systemcan be achieved andimplemented in engineer..In this paper, a type of power generation system is choosed as the object of study,andmuch intensive work has been carried out by means of simulation to analyze the systemstability, Along with the solution of system oscillation in system test, the optimization programis raised and the system experiment has verified that it improves stability of power systemswork.Firstly, the paper introduces the framework,operating principles and typical workingconditions of the power system,.Possible factors which have caused the system oscillation arelisted.Then through establishing the three-dimensional model and using finite elementanalysis method, the mathematical simulation model of double Y coil uni-pole inductivegenerator is established. Combined with the practical engineering circuit diagram, theautomatical voltage adjustor mathematical simulation model and the dynamoelectricrudder mathematical simulation model are establish. And then by using Simplor simulationsoftware the dynamic characteristics of two types of power system which are in engineeringapplication have been analysed in dynamic characteristics and stability.Through simulationand analysis, we found the factor which has caused the power generating system oscillationin large load disturbance conditions.Finally, on the basis of simulation, the designparameters of the power system is optimized and a lot of system experiments have verifiedthe system stability is greatly improved..This article also analyses the dynamic performance and stability margin of the choosedobject power system, and establishes a credible model.All the achievement lay a concretefoundation for the subsequent research.
