Model-Based Design and Optimization of Hybrid DC-Link Capacitor Banks [PDF]

IEEE Transactions on Power Electronics, 2020
For the applications where a single capacitor is incapable to meet the needs, multiple capacitors are connected in series or in parallel as a bank to fulfill the capacitance and voltage rating requirements.

Continuous monitoring of a capacitor bank

IEEE Instrumentation & Measurement Magazine, 2001
We have developed a prototype system for safety assurance of a capacitor bank by combining application-specific and off-the-shelf surveillance technology for remote monitoring. Traditional surveillance technology passively records facility operations, waiting for an event to trigger a physical audit of the collected information.

Thermal Modeling of an Electrolytic Capacitor Bank

2020 IEEE 21st Workshop on Control and Modeling for Power Electronics (COMPEL), 2020
This paper proposes a capacitor bank thermal impedance model considering the coupling between capacitors. FEM simulations and experimental characterizations are performed on 450 V/5.3 mF electrolytic capacitors. The comparative results verify the effectiveness of the proposed thermal model.

A primer on capacitor bank protection

IEEE Transactions on Industry Applications, 2001
Capacitor banks are applied in power systems to provide reactive power. The reactive power results in lower current in lines upstream of the bank improving system voltage and power factor and reducing line losses. Capacitor banks can be configured as filters for harmonic reduction.

Protection of large capacitor banks

Review of Scientific Instruments, 1983
Large capacitor banks, as used in many pulsed plasma experiments, are subject to catastrophic failure in the event of a short in the output or in an individual capacitor. Methods are described for minimizing the damage and down time caused by such a failure.

A study of capacitor element failures in high voltage Shunt Capacitor Banks

2017 IEEE 30th Canadian Conference on Electrical and Computer Engineering (CCECE), 2017
Internal 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, 1951
ONE 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.
