摘要
三峡机组单机容量大,单机或多机突然跳闸解列会给电网造成巨大的冲击,严重威胁电力系统的安全运行。发电机定子绕组冷却水系统故障是影响机组稳定运行的重要因素之一,文章通过对ALSTOM和VGS两种机型不同负荷下定子绕组冷却水中断试验的介绍和比较,以及断水运行对发电机的影响分析,进而提出三块左岸电站机组断水时的运行方式。
The capacity of Three Gorges units is very big.If one or more units trip accidentally,the power grid would suffer enormous shock.This will seriously threaten the electric system safety.The failure of stator winding cooling water system is a important factor to influence the units stably operate.By making a comparison between ALSTOM units and VGS units with the cool water interruption test for stator windings under different loads,analyzing the influence to the generator with interrupting water supply,the paper puts forward the running mode while the water is interrupted.
