Considerations for the application of series capacitors to radial power distribution circuits

This paper summarizes many of the considerations in the application of series capacitors on radial distribution circuits. The effects of series capacitors on receiving end voltages are illustrated via phasor diagrams and power-voltage characteristics. The unique voltage profile of the compensated distribution circuit is presented. Discussed are the various types of distribution circuit problems that series capacitors typically used to solve. Application guidelines are presented to help minimize oscillatory interactions with transformers and motors. The various protection schemes used in practical series capacitor banks are discussed. The information required to specify distribution series capacitor banks is outlined.

Effects of a Series Capacitor on the Energy Consumption in Piezoelectric Transducers at High Vibration Amplitude Level

In this paper, a driving method for low-loss generation in piezoelectric transducers at a high vibration amplitude level is presented. First, we analyze the power consumption of several loss mechanisms of piezoelectric transducers using an electrical equivalent circuit model. In this model, loss due to piezoelectric effect is explicitly represented by a series resistor, and pure dielectric loss is separately denoted by a parallel resistor. Mechanical loss is represented by a series resistor in the mechanical arm. The reason for the high efficiency at the anti resonance frequency is explained by this analysis. Next, the effect of an external series capacitor is discussed by comparing the experiment with the calculation, based on the equivalent circuit model for the high vibration amplitude level. By using the external series capacitor, the loss generated at the high vibration amplitude was significantly reduced without a large increase in electrical impedance.

Effects of series capacitors in transmission lines

THE LOAD capability and performance of high-voltage transmission lines can be improved by the installation of series capacitors. Some reasons for the application of series capacitors to transmission circuits are: 1. To effect the desired load division between parallel circuits. 2. To increase the load capacity of a transmission line by a nominal amount (0 to 50 per cent). 3. To provide increased line capacity so that the system can handle short-time emergency loads. 4. To increase the transient stability limits of a system. 5. To improve voltage regulation and power factor for a given load condition by reducing the operating angle of the line.
