High-voltage reactive power compensation devices are widely used to improve power quality countermeasures, including reactive power compensation, suppression of pulse current, reduction of operating voltage fluctuations and flicker, and processing of three-phase unbalance.

Equipment for reactive power compensation and harmonic control, such as passive power engineering filters, which have both reactive power compensation and voltage transformation, usually based on the main parameters of the pulse current source and the electrical equipment at the installation point. Features and customer-specified professional design scheme; static passive reactive power compensation device (SVC) equipment is the key machine equipment for such environmental rectification work voltage fluctuation and flicker, pulse current and its working voltage imbalance. Active Power Engineering Filter (APF), APF is a new type of power engineering electronic device that suppresses pulse current and compensates reactive power. It can measure pulse current and reactive current with large changes in frequency and amplitude. The compensation is implemented and the key is applied to the power distribution room system software.

In the development trend of reactive power compensation technology, I personally experienced the movement from the same camera to the power switch to the fixed fixed capacitor → static passive reactive power compensator (SVC) → attention to the static and reactive reactive ultrasonic waves SVG (STATCOM) is a lot of different links.

According to the basic principle of construction, SVC technology is divided into: self-saturated reactor type (SSR), thyristor phase-controlled reactor type (TCR), thyristor switching capacitor type (TSC), high-impedance impedance change. Reactor type (AR) operated by electrical type (TCT) and excitation regulator.

With the power electronics technology, the technical development trend of power-off components is very perfect, and countries around the world must develop, develop and design such a better high-voltage reactive power compensation device static passive power generation device (SVG). Although they are still in the process of development design and trial operation, and have not been technicalized, SVG will become more and more popular in power supply systems due to its excellent characteristics.
