绥电4号机组汽流激振原因分析

The Analysis on Steam Excitation of No.4 Unit in Suizhong Power Plant

近年来,随着经济、技术的发展和电网容量的扩大,我国火电机组的建设已跨上了百万千瓦级的台阶。根据大型超超临界机组产生汽流激振的特点及同类型机组参数的对比,针对绥电4号机汽流激振现象,通过试验分析了发生激振的主要原因。

In recent years,with the development of economy and technology,and the expansion of network capacity in China,the construction of the thermal power units have reached the level of 1 000 MW capacity.The main causes of steam excitation is analyzed through comparisons of excitation characteristics of ultra supercritical units with that of units of the same type,in consideration of steam flow excitation phenomenon of No.4 Unit and by tests.
