300MW汽轮发电机组扭振的模拟试验研究

对东方３００ＭＷ汽轮发电机组的扭振进行了模拟试验研究，设计并制造了扭振模拟机及其扭振试验与测试系统，测试并分析了该模拟机的扭振特性。试验结果表明，扭振模拟机的前几阶扭振固有频率和振型与被模拟对象基本吻合，可以用来研究被模拟对象的扭振响应特性及其与电系统的耦合互作用规律。

Experiment of on Torsional Vibration of 300MW Simulated Turbine generator

The experiment research on torsional vibration of Dongfang 300MW simulated turbine generator has been completed.The experiment results showed the dynamic of the simulated machine is accordant with the Dongfang 300MW turbine generator,such as the first orders natural frequencies and the vibration shapes of torsional vibration,therefore the machine can be used to simulate the torsional vibration response characteristics and the principium of machine network interaction for Dongfang 300MW turbine generator.On this basis,the experiments of torsional vibration response to the disturbances due to network faults and subsynchronous resonance on series of complimentary capacity have been carried out.
