loss of excitation meaning in English
失磁
Examples
- For synchronous generator , loss of excitation is a serious fault and the corresponding protection often refuse to operate or maloperate
发电机低励失磁故障是一种严重的故障形式，低励失磁保护也是发电机保护的重点和难点。 - It ’ s important for us to analyze the dynamic excitation - loss process precisely . in this paper , by use of the selected blocks from power system library in matlab , the author sets up a generator - infinite system and simulates the loss of excitation fault
目前低励失磁保护误动、拒动的情况时有发生，为了对保护判据进行合理改进，就要深入研究失磁的动态过程。 - Therefore , the stable operational region of generators is discussed along with the analysis on relationship between under - excitation operation and loss of excitation / synchronism , end temperature rise of stator - core , and automatic excitation regulators etc
针对这种情况，对发电机稳定运行区域进行了探讨，并对进相运行与失磁失步、进相运行与定子铁心端部过热、进相运行与自动励磁调节器等关系作了分析。 - Based on the simulation , the author analyzes the dynamic process and gives reasonable explanation . then the author uses a three - layer ann to distinguish excitation - loss fault , and brings forward a scheme of excitation - loss protection using ann for generator . finally , the author discusses the setting calculation software for generator , and design the part of setting calculation software including partial or total loss of excitation protection
