摘要
综合分析了电网-机组相互耦合可能产生的一些新问题。论述了引起轴系扭振损坏的各种类型和原因,给出了相应的事故案例。在统计和分析的基础上,指出,扭振引起的事故占轴系振动损坏事故中的首位。并对扭振技术的开发提出展望。
Some problems that may arise by interaction of the electric network with a turbine-generator set are comprehensively discussed. Possible causes of torsional vibration damages are discussed with corresponding examples of failures. On the basis of statistics and analysis, the paper points out that torsional vibration ranges first place in vibration failures of shafting system. A prospect of vibration analysis technique development is also given.
