tailieunhanh - HARMONICS AND POWER SYSTEMS by Taylor & Francis Group

In a normal alternating current power system, the voltage varies sinusoidally at a specific frequency, usually 50 or 60 hertz. When a linear electrical load is connected to the system, it draws a sinusoidal current at the same frequency as the voltage (though usually not in phase with the voltage). When a non-linear load, such as a rectifier, is connected to the system, it draws a current that is not necessarily sinusoidal. The current waveform can become quite complex, depending on the type of load and its interaction with other components of the system. Regardless of how complex the current waveform. | HARMONICS AND POWER SYSTEMS Copyright 2006 by Taylor Francis Group LLC The ELECTRIC POWER ENGINEERING Series Series Editor Leo L.
