摘要
目前飞机上广泛使用的大都是恒速恒频的交流发电机系统,与之相比,高压直流供电系统的应用前景更为广阔。因具有重量轻、效率高、不中断供电、滤波要求简单和易于实现等一系列的优点,使其更能适应航空电力系统供电装置。但随着航空技术的飞速发展,飞机电气系统的设备越来越多,控制系统结构日益复杂,电气系统的浪涌、尖峰脉冲等都会使飞机系统产生误动作,一直影响飞机系统的作战任务,因此对于可靠的电气系统的研究具有重大意义。

其次,分析了高压直流发电系统调压器可能产生的故障原因以及故障点,根据分析对故障进行了分类,建立了故障分析表和故障码表。
最后,根据功能需求对高压直流发电系统调压器故障检测系统进行了分析和设计,主要包括直流调压器故障诊断、故障诊断过程、故障检测各部分软件的设计,并对高压直流发电系统调压器故障检测系统进行实现。
测试结果表明,本文中所设计的调压器的功能和性能指标均能满足高压直流发电系统的需要。同时,调压器故障检测系统不仅能够快速地检测出故障点,而且还能对故障原因进行显示。
Now which widely used in aircraft are mostly constant speed constant frequency AC generator system, compared to high voltage DC power supply system is more broad application prospects. It is light weight due to high efficiency, uninterrupted power supply, filter requiring a simple and easy to implement some of the advantages of the column, which can adapt to the air of power supply devices. But with the rapid development of aviation technology, aircraft equipment, electrical system, more and more structure, more complex control system, electrical system surges, spikes and so will produce aircraft system malfunction, the system has been operational mission of the aircraft, Therefore, a reliable electrical system for the research is very necessary.
This study covers the following aspects:
Firstly, high-voltage DC power system voltage regulator working principle described in detail, the design of the high voltage DC power regulator of hardware, including excitation power the main circuit, overvoltage and under-voltage protection circuit, the voltage detection circuit, PWM pulse generating circuit, power driver circuit, excitation current detection circuit. Established a regulator in the frequency domain model, and the soft real Simulink software design on the paper, the regulator of the model simulation.
Secondly, the analysis of high voltage DC generator voltage regulator and the causes of possible failure points, according to the analysis and classification of faults were established failure analysis and fault code table .
Finally, the functional requirements of high voltage direct current power system voltage regulator fault detection system analysis and design, including the DC voltage regulator fault diagnosis, fault diagnosis, fault detection of the various parts of the software design, and high voltage DC power system transfer pressure to achieve fault detection system.
Test results show that the function and performance of pressure-regulator in the design can meet the needs of high-voltage DC power generation system.
Meanwhile, the regulator fault detection system not only can detect the fault quickly, but also display the reasons for failure.
