The combined sections method overcomed the disadvantage of method only considering active or reactiveload and improved the accuracy.
这种组合分段的方法克服了仅按照有功或无功分段的缺陷,提高了控制的准确性。

The methods of using reserve excitation device, transferring reactiveload and dropping reactiveload are put into service for detecting polarity in Gezhouba Hydropower Plant.
Based on equivalent four-terminal networks of the longitudinal ultrasonic transformer, the resonant frequency equation and the amplitude magnification coefficient, with reactiveload, are studied.
