Shunt capacitors are commonly used in distribution system for reactive power compensation. Different analytical, numerical programming, heuristic and artificial intelligent based techniques have been proposed in the literature for optimum shunt capacitor bank (SCB) placement. This paper will present a very detailed overview of optimum SCB placement techniques. Six different approaches of optimu...

These models are suitable for analysis in the time domain, which is especially useful for load transient simulations. Linear models that can be transformed to the frequency domain for analysis are derived from the Hamiltonian models. The duty cycle is included in the input signal vector, enabling full system analysis with respect to the system’s transfer functions: audio susceptibility, output ...

This paper gives recent results of experiments with a coaxial Plasma-Pulse-Accelerator (PPA). Discharging a capacitor bank into the PPA more than 80 % of the stored energy could be transferred from the electrical circuit into the plasma. Accelerating masses of 10 g to velocities of 1020 m/s overall efficiencies of 22 % were achieved. A 3 g mass could be accelerated in the same PPA to 2000 m/s; ...

We have developed a repeating pulsed magnet system which generates magnetic fields of about 10 T in a direction transverse to an incident beam over a length of 0.8 m with a repetition rate of 0.2 Hz. Its repetition rate is by two orders of magnitude higher than usual pulsed magnets. It is composed of four low resistance racetrack coils and a 30 kJ transportable capacitor bank as a power supply....

Dynamic security assessment (DSA) or transient security assessment (TSA) determines a system’s ability to survive contingencies with a safety factor (margin). To ensure that a system remains dynamically secure, preventive or corrective remedial actions are designed. Preventive actions are applied in the pre-contingency system so that after any credible contingency the system remains secure. Exa...

In this paper, simultaneous placement of distributed generation, capacitor bank and protective devices are utilized to improve the efficiency of the distribution network. The objectives of the problem are reduction of active and reactive power losses, improvement of voltage profile and reliability indices and increasing distribution companies’ profit. The combination of firefly algorithm, parti...

It is shown that self-heating of electrolytic capacitors causes the output current of a capacitor bank to increase with successive shots even though the charge voltage is held constant. Self heating of only 10 °C can cause a near tripling in the gas output of the gas puffing valves commonly used in spheromak research. By using metallized polypropylene film capacitors instead of electrolytic cap...

The design of a 500 MHz oscillator in a 65 nm CMOS process using a 2 GHz bulk acoustic wave (BAW) resonator is presented. A digital frequency control is implemented using a switched capacitor bank in parallel to the resonator. The tuning range is up to 500 kHz with a minimum step of 200 Hz. The oscillator core uses a differential topology and is designed for low phase noise (2128 dBc/Hz at 100 ...

Photovoltaic power plants usually do not provide reactive output; hence the application of large photovoltaics in systems will decrease voltage stability level system. Capacitor banks can to compensate photovoltaic plants; therefore, capacitor overcome deficiency plants. However, effect bank installation on system’s is unknown. Therefore, research aims investigate whether installing a capacitor...
