摘　　要：针对某飞行台被试发动机试验要求,设计研发了一套被试发动机交发电机电负载系统,介绍了该电负载系统的结构、控制方式、实现方法及功能特点。该系统采用风冷式外挂吊舱内置星形纯阻性负载的模式,可针对被试发动机中频交发电机实现总功率为175kVA、最小调节量为1kVA的任意需求负载的加载试验及监控。整个系统采用模块化设计,具有较好的通用性。The electrical loading system requirements of tested engine on the flight of alternator is designed after analyzing the test test bed. The structure, control and implementation method and functional characteristics of the system are introduced in the paper. The system use the mode of air-cooled cabin hanging out of the flight test bed with star structure resistive loads in, and can control and monitor the electrical loading process of medium-frequency alternator of tested engine in the range of 0 ~ 175kVA with minimum adjustment quantity of lkVA. By adopting modularity design, the system has good universality.
