在温汤地热试验电站中,由于汽轮机进汽汽压很低(仅数公斤/厘米~2),影响了汽轮机的效率。为了减少进汽压力损失,提高汽轮机效率,在电站设计就考虑到不在汽轮机进汽管道上装设调速汽门,而使在汽轮发电机组正常运行时的转速稳定,依靠调节发电机的内负荷来实现。这不同于通常电站所采用的调速方法。温汤电站在自动调速器未安装前,是由人工频繁地操作开关、闸刀来改变内负荷(电炉丝、灯泡),以使发电机组转速保持稳定,但当
In Wen Tang geothermal test station, due to the steam turbine steam pressure is very low (only a few kg / cm ~ 2), affecting the turbine efficiency. In order to reduce the intake pressure loss and improve turbine efficiency, taking into account the design of the power plant steam turbine inlet pipe is not installed on the speed control valve, leaving Turbine Generator Unit normal operation of the speed stability, by adjusting the generator load to fulfill. This is different from the speed control method commonly used in power plants. Wen Tang power plant in the automatic governor is not installed before the manual is frequently operated by the switch, the knife to change the internal load (electric wire, light bulb), so that the speed of the generator set to maintain stability, but when
