Multi-objective Optimization of Capacitor Bank Considering the Parasitic Parameters of Capacitors
8th Renewable Power Generation Conference (RPG 2019), 2019For the applications where a single capacitor is incapable to meet the needs, different types, behaviors and specifications of capacitors can be packaged as a capacitor bank to fulfill the requirements of the systems. Even though some commercial capacitor bank products have already existed in the market, most of them are the experienced based design ...

Capacitor control relaying for switched capacitor banks
1988. Rural Electric Power Conference, Papers Presented at the 32nd Annual Conference, 1988The development of an advanced capacitor bank control relay, its measurement techniques, its control parameters, and the applications for which it is suitable are described. The use of the relay in automated distribution systems, typical distribution loss improvements due to an increase in the number of switched capacitor locations, and the need for ...

A study of capacitor element failures in high voltage Shunt Capacitor Banks
2017 IEEE 30th Canadian Conference on Electrical and Computer Engineering (CCECE), 2017Internal failures in Shunt Capacitor Bank (SCB) units render trips from unbalance protection to prevent from further damage to the equipment. Fuseless and internally fused capacitor cans are the dominant technologies in power capacitor design, which do not provide external indication for units with failed elements.

Switching High-Voltage Shunt Capacitor Banks
Transactions of the American Institute of Electrical Engineers, 1951ONE OF THE first 34.5-kv capacitor banks in this country was installed recently on the Indianapolis Power and Light Company system. This capacitor bank, totaling 7,290 kva, was part of a system program of adding reactive generation close to reactive load in the most practical and economical manner. See Figures 1 and 2.

Switched-Capacitor Power Converters With Soft Charging via Auxiliary Capacitor Bank
2019 IEEE 62nd International Midwest Symposium on Circuits and Systems (MWSCAS), 2019This paper presents a circuit solution for increasing the efficiency of switched-capacitor power converters utilizing a soft charging technique. The technique is based on an auxiliary capacitor bank that reduces the energy losses associated with parasitic capacitances.

Influence of Harmonic on the Protections of Capacitor Bank
Applied Mechanics and Materials, 2013This paper introduces the capacitor bank equipped with overvoltage protection and overcurrent protection. Then with a group of capacitor for reactive power compensation as the research object, this paper analyses the influence of harmonic to the two protection modes when the electromagnetic, static or microcomputer relay are applied.

Reliability Evaluation and Optimization of Capacitor Bank
2018 IEEE Energy Conversion Congress and Exposition (ECCE), 2018Capacitors are widely used in power electronic converters to buffer the pulsation power, filter the harmonics and support voltage for stable operation. For these applications where single capacitor can not fulfill the voltage rating or capacitance requirements, capacitor bank is always used as the energy buffer by connecting several capacitors in ...

High Voltage Charging of a Capacitor Bank
IEEE Transactions on Plasma Science, 2008We have demonstrated the feasibility of charging a capacitor bank to a high voltage using an autonomous ultra-compact explosively driven source of prime power. The prime power source is a longitudinally driven shock wave depolarization of a ferroelectric ceramic.

Control of Overvoltages on Energizing Capacitor Banks
IEEE Transactions on Power Apparatus and Systems, 1973Transient voltage phenomena occurring during the energization of shunt capacitor banks, due to prestrike and temporary interruption in the switching device of inrush currents have been considered. An analysis is made of a generalized capacitance circuit and energization transient voltage pattems are shown for a range of circuit permutations.
