Abstract: Electric power is very important for a series of social activities, such as the operation and production of enterprises, people's life and work, and so on. The more developed the economy, science and technology, the greater the demand for electricity in various industries. The power plant bears the responsibility of power supply, and whether the power supply is safe and stable will have an impact on the whole society. Steam turbine is an important equipment in power plant, and the operation status of steam turbine will directly affect the whole power supply system. In this paper, the faults with high incidence of steam turbine in power plant are analyzed, and the corresponding solutions are put forward.

汽輪机的结构比较复杂,在恶劣的环境中运行,所以很容易发生各种各样的故障,如果不能及时、有效的排除故障,甚至会酿成重大事故,造成不可挽回的损失。可见,汽轮机的安全运转是发电厂正常运行、保证电力供应的前提条件。准确的识别汽轮机的故障类型,采取针对性的故障排查措施和技术,及时解决故障,对于保证发电厂供电的稳定性与安全性十分重要,本文就此展开探讨。
1 发电厂汽轮机介绍
发电厂是通过天然气、煤炭、石油等燃料来产生电能的,工作过程可以概括为:燃料放入锅炉内燃烧,不断的加热水产生蒸汽,在蒸汽的作用下,原本属于化学能的燃料会转化成热能。利用高温蒸汽压力促进汽轮机的持续运转,把热能转化为机械能,以推动汽轮机的运行。汽轮机又会带动发电机运转,最终把机械能转化为电能。根据燃料的类型,又可以把发电厂分为天然气发电厂、工业废料发电厂、余热发电厂、燃煤发电厂等几种类型。……
