SVG Hybrid Active Power Factor Correction

YT-PQC-HPFC SVG Hybrid Active Power Factor Correction

YTPQC-HPFC Hybrid Active Power Factor Correction adopts the configuration scheme of combining YTPQC-ASVG Advanced Static var Generator and switching capacitor/reactor, and implements different reactive compensation schemes according to the actual needs of users on site, so as to achieve the best combination of price and effect.

YTPQC-HPFC Hybrid Active Power Factor Correction device consists of two parts: Static Var Generator and switching capacitor / reactor reactive compensation unit. In YTPQC-HPFC hybrid dynamic reactive power compensation device, each unit is designed and produced in the method of low power, small volume and low cost, and both of them are optional, and can be combined in the best and flexible way according to the actual reactive state of the site, so as to achieve the optimum ratio of operation effect and cost.

A united system of thyristor switched capacitor (TSC) and YTPQC-SVG static var generator was proposed to improve voltage regulation, stability, and power factor in ac transmission and distribution systems. The TSC is consisted of multi-groups binary-coded capacitors, which is mainly used for large capacity var compensation step by step. YTPQC-SVG compensates small capacity reactive power continuously, and filters harmonics generated by the nonlinear load.

When YTPQC-SVG compensates harmonics with traditional control method, it may run into oscillation if the YTPQC-SVG controller does not consider the interaction between TSC and YTPQC-SVG, so a selective harmonic compensation method is present to solve the problem. A predictive control algorithm for TSC is studied to have a correct compensation when the load changes rapidly. The proposed united compensation system can implement continuous reactive power and harmonic currents compensation cost-effectively.

Modular Design

YTPQC Static Var Generator has a advanced modular design. Usually YTPQC-SVG consists of one or severalVG S modules and an optional touched LCD Human Machine Interface. Each SVG module is an independent harmonic filtering system, and users can change the harmonic filtering system rating by adding or removing SVG modules.

According to the mounting type, YTPQC-SVG can  be divided into Rack Modular SVG,Wall-mounted SVG and free landing SVG.
