In the optimal distribution module of reactive power, the device adopts Staitc Var Generator and TSC hybrid mode of reactive power compensation. SVG detects the reactive power of the system, controls the switching of capacitors, and determines the capacity and timing of its own reactive power generation. The capacity ratio of SVG and TSC can be configured; for applications with slow reactive power...
In modern industrial processes, the number of nonlinear loads - known to be a major source of current harmonics - is constantly growing. At the same time, the number of reactive-power compensators operating in these networks is growing too. Though the compensators are not the source of harmonic distortions, they may cause high amplifications of harmonics by creating resonance conditions. This can ...
Introduction To Capacitors And Reactors Reactance includes inductive reactance and capacitive reactance, and reactor includes inductive reactance (inductor) and capacitive reactance (capacitor). Inductance has the function of "blocking AC and blocking DC", that is, in the AC circuit, the characteristics of inductive reactance are used to "pass low-frequency DC and block high-frequency AC". The cap...
Power Factor Correction Power Factor Correction improves the phase angle between the supply voltage and current while the real power consumption in watts remains the same, because as we have seen a pure reactance does not consume any real power. Adding an impedance in the form of capacitve reactance in parallel with the coil above will decrease Θ and thus increases the power f...
Site conditions The site is located in Hangzhou Asian Games Village.The project has more than 20 power distribution rooms. Due to the main load being fire-fighting facilities, which are generally not started, the transformers almost all operate without load, and the cable length is long, resulting in capacitive reactive power at both the high and low voltage sides, which cannot be compensated by t...
SVG (Static Var Generator) and conventional capacitor bank are both devices used in power systems for reactive power compensation, but they have significant differences in terms of operation, performance, and flexibility. Here's a comparison between SVG and conventional capacitor bank: 1. Operation: - SVG: SVG uses power electronics-based technology to dynamically control and r...
The relationship between capacitors and harmonics is very close, especially in power systems. The use of capacitors can affect the generation and propagation of harmonics, and are also easily affected by harmonics, leading to reduced performance or damage. Harmonic amplification In the power system, capacitors have a lower impedance to harmonics, so harmonic currents tend to flow through th...
The harm of harmonics to power capacitors mainly includes the following aspects 1. Overcurrent and Overload -Harmonics can cause distortion of voltage and current at the capacitor terminals, especially at specific harmonic frequencies, where capacitors resonate with inductive components in the system, resulting in significant amplification of harmonic currents. Excessive harmonic current causes th...
