某型民机电源系统发电机控制器一体化测试系统研制

Development of integrated test system for generator control unit of certain civil aircraft power system

随着多电飞机、全电飞机高速发展,对民机电源系统各控制部件,尤其对发电机控制器(GCU)提出更高的质量要求和测试系统建设需要。为降低测试系统技术输入难度和后续能力扩展费用,提升我国民机系统核心部件的部件级测试水平,首先比对了国内外民机主制造商在部件级测试领域的能力现状,然后详细分析了某型民机电源系统发电机控制器的结构功能、技术指标,最后从该发电机控制器的测试需求出发,提出一种通用化、标准化、模块化的一体化测试系统,通过建立电源系统核心部件功能、性能验证及排故、维修能力,力求覆盖入厂接收检验严格管控、总装地面功能试验高效排故、外场运营维护快速响应多应用场景测试要求,最终实现我国民机测试保障体系的建设目标。

With the rapid development of multi-electric aircraft and all-electric aircraft,higher quality requirements and test system construction requirements have been put forward for each control component of the civil aircraft power system,especially for the generator control unit(GCU).In order to reduce the technical input difficulty of the test system and the cost of follow-up capability expansion,and to improve the component-level testing level of key components of our civil aircraft system,this paper firstly compares the capabilities of domestic and foreign civil aircraft manufacturers in the component-level testing field,and analyzes the structure function and technical indicators of generator controller for a certain type of civil aircraft power supply system.Finally,Starting from the test requirements of the generator controller,a generalized,standardized and modular integrated test system is proposed.By establishing the core of the power system component function,performance verification,troubleshooting,and maintenance capabilities,we strive to cover the strict inspection and control of incoming acceptance inspection,efficient troubleshooting of general assembly ground function tests,and quick response of field application operation and maintenance to multi-application scenario test requirements,and finally achieve the goal of building our national aircraft test support system.
