八盘峡电站的瑞典FRVV-103-2电液调速器的鉴频器采用逻辑电路和集成块元件。国产电液调速器鉴频器也有采用类似原理的。现将FRVV-103-2电液调速器鉴频器的原理分析如下。
The frequency discriminator of Sweden FRVV-103-2 electro-hydraulic governor of Bapanxia power station adopts logic circuit and integrated block components. Domestic electro-hydraulic governor frequency also have a similar principle. Now FRVV-103-2 electro-hydraulic governor frequency analysis principle is as follows.
