YT Hybrid Power Factor Correction: Section 3

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 change and small range, use small-capacity SVG to increase Rongxing TSC; for applications with fast reactive power change and large range, use larger capacity SVG plus appropriate Capacity TSC scheme.

Five functional areas of intelligent hybrid reactive power compensation device

1. Fast reactive power calculation module, which can realize power factor calculation, Static Var Generator power calculation and other functions;
2. Reactive power optimization distribution module, which can realize the functions of determining the switching control of the capacitor bank and determining the reactive power output of the reactive power generator;
3. SVG module, which can realize feedback control of output voltage and current, PWM control selection and other modules;
4. Human-machine interface module, which can realize the interface access function of LCD panel;
5. DSP control module, which can realize the functions of signal acquisition, PWM output, man-machine interface function and external communication.

During site operation, TSC compensates large-capacity or fixed reactive power; while for small-capacity and fast-changing reactive power, Static Var Generator compensate the reactive power quickly, achieving fast reactive power compensation response (less than 5 milliseconds) and high performance. Power factor compensation (greater than or equal to 0.98).
