摘要
某型直升机雷达系统在训练过程中,频繁发生设备过载和电源过载等故障,暴露出飞机电源系统与雷达系统存在较为严重的适配问题。以往,对于飞机电源系统进行分析通常是采用试验的方法,但是,需要投入大量的人力物力和财力,并且还存在可能烧坏电机设备的问题。因此,采用数字仿真技术,以雷达系统作为负载,研究电源适配性,具有比较大的现实应用意义。通过对某型直升机电力滤波器模型进行仿真,分别介绍了有源电力滤波器中对于谐波电流的检测的方法,i_p、i_q运算方式的选择原因,并且解决了此方法不适用于三相四线制的问题,运用滞环比较法控制策略,对电力电子开关进行控制,实现滤除谐波的功用。
During the long-time training of the radar system, the situations of equipment overload and over current fault frequently occur, which exposes that a helicopter power supply system and its radar system do not match. Test methods were used to analyzed the on-board electrical power, which costed too much time and money. So it has higher efficiency to use simulation methods to study the compatibility between on-board electrical power and radar system. In order to eliminate the harmonic wave and improve the suitability of special load and motor, and the model of active power filter is designed. Through comparison and analysis, the IP- IQ method is used as the instruction current detection method. In the meaning time, the problem that it didn＇t match with three-phase four-wire system is solved.
