Research And Design Of Aircraft Power Systems Power Protection

In the 21st century, it has become a major concern for most countries whether energy can be cleanly and efficiently used. Comparing to other types of power devices, Gas Turbine is characterized by its high efficiency, high reliability, high adaptability to fuels, low environmental pollution, low or little water consumption. Nowadays, with the development and assembling of series of Gas Turbine generating systems, the Gas Turbine power has contributed a lot to national consumption.The society becomes increasingly depended on the electricity, which poses a higher demand to the quality of the power supply. With the installation of a large number of units and the expansion of the power network, higher request has been put on the safety and performance of the power industry.Thus, it is very important to equip it with reliable safety monitoring device and protection system. Therefore,for our aircraft power development, it is of great importance to develop an advanced dynamic protection system in aircraft power generation.This thesis mainly achieves the design and realization of the aircraft power protective system. Firstly, it gives an introduction to the general information of the system, and designs the overall structure of the protection system and the protective strategies of specific detection ranges. Furthermore, it elaborates on the hardware structure of the protective system and carries out a feasibility analysis on it. According to the strategies, software programs are designed and detailed analysis is given to the relative software structures. Some cognizance into the protection system has been gained by the analysis and the design of the hardware and software of the system.At last, according to the field outline of debugging, debugging and field tests are carried out into each protective module. Results show that the protective system mentioned in the thesis not only meets the basic needs of the aircraft power system, but also efficiently improves the security, reliability, stability and economical efficiency of the system performance.
