基于Saber的飞机发电机并联建模与仿真研究

针对典型发电机并联供电性能的检测仍借助人工测试完成，对其进行真实的物理实验跟踪记录较为困难等问题，提出利用微增量法建立低压直流发电机的数学模型，采用平均电流均流法建立发电机并联控制模型。在Saber仿真环境下建立并联系统分别模拟飞机发电机在稳定状态、投入切除并联及突加突卸负载状态下系统的运行情况。仿真结果表明，建立的模型真实有效、仿真精度高，能为真实的电机设计提供参考。

Parallel Modeling and Simulation of Aircraft Generator Based on Saber

The detection of typical generator power supply capacity is still done by means of manual tests, its actual physical experiments are difficult to keep track of.This paper establishes a mathematical model of low-voltage DC generator with the micro-increment method, and uses the average current method to establish the generator current-sharing control model.Under Saber simulating conditions, the parallel system is established to simulate the operation of aircraft generators system in states of steady, input and the sudden removal of, and load-unload.Simulation results show that the model is valid, simulation accu-racy is high, and can provides a reference for an actual generator design.
