摘要
对老水电机组进行更新改造,投资小,见效快,且结合更新改造可以进行一定的增容,这是已经被人们普遍认同的。刘家峡水电厂在西北电网中主要承担发电、调峰、调频和调压任务,是西北电网的骨干电站,在西北电力系统中处于十分重要的地位。全面提高机组的可靠稳定运行对于电厂安全、高效具有重要意义。
     刘家峡水电厂五台机组自1974年全部投产发电,由于受当时技术条件的限制,设备运行二十多年后,可靠性明显降低,水轮机磨损严重,发电机绝缘老化,技术落后,自动化程度低,已迫切需要更新改造,结合改造,利用现代先进技术对机组进行增容,投资省,效益好。
     由于水轮机水力性能的研究水平和测试手段不断提高,近年来产生了一大批性能很好的新型转轮,为老水电机组的增容改造提供了技术保证。
     本人参加工作时,正值刘家峡水电厂机组改造起始阶段,参与了五台机组增容改造的全过程。本文以水轮发电机组为主要研究对象,对刘家峡电厂的水轮发电机组增容改造工作从可行性分析到具体改造进行详尽的阐述,重点分析机组增容改造的现实意义,旨在为我国老水电企业的机组增容改造提供宝贵的经验。
It is commonly accepted that it takes less investment and gains quick benefit to rehabilitate a old hydraulic generating set and enhance its capacity at the same time. As a backbone of the Northwest Power Network, Liujiaxia Hydropower Plant plays the roles of generate electricity, peak modulation, frequency modulation and voltage modulation. It is quite important to improve the reliability of operation for the safety and the high efficiency in power plant.
    Liujiaxia Hydropower Plant has 5 generating sets. All the sets began to generate electricity in 1974. Because of the restriction of technology at that time, these problems come out: clearly degraded reliability, serious abrasion of turbine, aging of generator insulation, outdated technology, low automatization. It' s necessary to rehabilitate. We can enhance the capacity, using advanced modern technology during the rehabilitation. It costs less investment, but we much benefit.
    A lot of new runners with high performance are produced in recent years because the study and the test methods of hydraulic performance of turbine are upgrading endlessly, which provides a technical guarantee to the old hydraulic generator sets.
    It is the beginning of the rehabilitation in Liujiaxia Hydropower Plant when I started to work, so I participated in the whole rehabilitation. The article expatiates the feasibility and the materiality of the rehabilitation of generator sets in Liujiaxia Hydropower Plant. It mainly analyses the practical significance of the rehabilitation, so as to give old hydropower enterprises some precious experience.
