400Hz 变速恒频交流航空发电系统瞬态参数的测试问题一直是我国有关单位研究的课题,但只限于对某单个参数的测试探讨。美国波音公司七十年代用小型计算机实施瞬态参数测试。本文介绍我们研究的小型计算机测试系统能在一周(360°)范围内实时连续测瞬态峰值、频率及相角值由计算机处理。实践证明,这样的系统能对发电系统的各种瞬态参数实施综合全面的测试(也能单个参数测试),基本上能满足航空发电系统瞬态测试的要求。文中阐述了系统测试原理及参数测试应用。系统有通用性,可推广于其它交/直流系统和发电系统。
The testing of transient parameters of 400Hz VSCF AC power generation system has always been the subject of our country’s relevant research, but it is limited to the test of a single parameter. Boeing in the United States in the seventies with a small computer to implement transient parameter testing. This article describes the small computer test system we studied in a week (360 °) continuous real-time measurement of transient peak value, the frequency and phase angle value by the computer. Practice has proved that such a system can implement a comprehensive and comprehensive test (also a single parameter test) on various transient parameters of a power generation system, and basically can meet the requirements of the transient test of an aviation power system. The article describes the system testing principles and parameter testing applications. System has versatility, can be extended to other AC / DC systems and power generation systems.
