Frequency deviation transducer for power system applications
暂无分享,去创建一个
A frequency deviation transducer using solid-state circuitry has been developed. The device is based on digital - analogue technique and is suitable for continuous record of power system frequencies and governor application with a high order of accuracy. No initial adjustments are required and no reset problems are faced. Depending on application requirements, the transducer may be used alone for direct measurement or in combination with other control equipment for automatic load frequency control, excitation control, load shedding and in acceleration relay applications etc.
