抽水蓄能电站具有水头高、水头变幅大、工况转换频繁和输水系统中存在双向水流等特性,使得蓄能机组在低水头下运行时,空载稳定性不好,难以并网。目前较为有效的方法是采用异步开导叶方法,但是通常会加剧机组的振动,给机组的长期运行带来不利影响。文中描述了异步开导叶方法在惠州蓄能水电厂机组的应用,并对比分析了相应的振动数据。
Pumped storage power station has the characteristics of high water head, large head amplitude, frequent changeover of working conditions and bi-directional flow in the water delivery system. When the accumulator is running at low water head, the no-load stability is poor and it is difficult to connect to the grid. At present, the more effective method is to use the asynchronous guide vane method, but it usually aggravates the vibration of the unit and adversely affects the long-term operation of the unit. The paper describes the application of asynchronous open vane method in Huizhou Pumped Storage Power Station and compares the corresponding vibration data.
