多媒体系统是近年来国际上出现的一种新的信息传播系统。它除了传播一般的文字和数据信息外,还可以传播音像信息。多媒体系统用于水电站的运行监测有很多好处。它除了一般的水位、流量、电压、频率、出力等数据信息以外,还可以监测到机组的整体形象和机器运行的声音,包括振动的声音、发电机的转子和定子之间的间隙、水轮机转轮与其周围部件之间的裕度。通过远距离传播,出现在控制中心的显示屏幕和音响终端上,极大地提高了水电站运行监测的质量。这一先进监测系统可以及早发现水电站运行中的异常现象,
Multimedia system is a new information dissemination system appearing in the world in recent years. In addition to disseminating general text and data information, it can also spread audiovisual information. Multi-media systems have many advantages for the operation monitoring of hydropower stations. In addition to general information on water level, flow rate, voltage, frequency, output and other data, it can also monitor the overall image of the unit and the sound of machine operation, including the sound of vibration, the gap between the rotor and stator of the generator, Margin between the wheel and its surrounding components. Through long-distance transmission, appeared in the control center of the display screen and audio terminal, which greatly improved the quality of operation monitoring of hydropower stations. This advanced monitoring system can detect anomalies in the operation of hydropower stations early,
