在民用飞机变频供电系统的设计和适航符合性验证试验中,负载特性的模拟是一项关键技术,为适应变频供电系统负载特性的综合测试和验证对负载模拟的符合性需求,论述了一种适应变频供电环境下的变频模拟负载作为模拟飞机115/200V、(360～800Hz)三相四线制变频供电系统负载的综合电气特性,并为之设计智能控制系统。通过在线优化阻抗参数,提高负载的闭环特性和自适应能力,确保变频供电系统负载电气特性参数测试的准确性。

Simulation of load characteristics is a key technology for designing of variable frequency power system in civil aircraft and means of compliance test. It adapts to testing of variable frequency power system and requirements which verify simulated load compliance.This paper presented one type of VF simulated load which simulated electric power characteristics in 115/200V,360~800Hz,three-phase wye system and design of control system. Optimizing impedance parameter improved closed-loop control and self-adapting ability to insure testing accuracy for electric load characteristics of variable frequency power system.
