多电飞机电力系统静态安全与稳定性分析

摘要

为研究多电飞机电力系统在工况切换和负载波动情况下的静态安全与稳定性,介绍了多电飞机电力系统的结构及特点;并对比陆地交直流混联系统,构建了适用的潮流模型.通过改进交替迭代算法,完成了对多电飞机交直流混联系统的潮流计算.通过MATLAB编写潮流计算程序,给出了不同工况下负载变化时的潮流计算结果,并制定出相应的稳定调节控制策略.%To study the static security and stability of more electric aircraft (MEA) electrical power system (EPS) under working conditions change and load disturbance,the structure and characteristics of MEA power system were firstly illustrated.Then,compared with the land normal AC/DC power system,the suitable static modes of MEA EPS were proposed.By improving the alternating iterative algorithm,the power flow calculation of MEA EPS was carried out.Finally,with the MATLAB power flow program,the calculation results and adjust strategy under different working conditions were proposed.
