摘要
直升机电磁式无刷同步发电机系统带不对称负载时,系统的性能分析对飞机电网来说非常重要。而常用仿真平台MATLAB软件中,电磁式无刷交流同步发电机模型不能用于不对称负载的仿真分析,针对这一问题,本文提出了一种基于abc/dq0变换的新型同步电机仿真模型,有效解决了系统带不对称负载时的建模问题。基于所建模型进行了一系列仿真分析,仿真结果验证了该模型的正确性和可行性,为直升机发电机系统分析与设计提供了有效方法。
The performance analysis of the brushless electromagnetic synchronous generator(BESG)with unbalanced loads is essential for the electric networks of helicopters.However,the BESG model presented by the MATLAB simulation platform is not suitable for the unbalanced loads.Based on the abc/dq0 transformation,this paper developed a novel simulation model which gives a solution for the performance analysis of BESG with unbalanced loads.Much simulation work is performed by means of the novel model,and the simulation results verify its correctness and feasibility.It also provides an effective solution method for the analysis and design of the helicopter generator system.
