Operating Principle

static var compensator circuit diagram

The basic principle of the FGSVG dynamic var compensator is to use a power-off electronic circuit device that can be turned off to form a self-commutated bridge circuit. The transformer or reactor is connected in parallel to the power grid, and the amplitude and phase of the output voltage of the bridge circuit are properly adjusted, or directly Control the output current, so that the circuit absorbs or emits reactive current that meets the requirements of the power grid, and achieves the purpose of dynamic Reactive Power Compensation.

Zero load operation: U1=Us,IL=0,SVG neither absorbs nor generates reactive power.

Characteristics of FGSVG Static Var Generator

1. Voltage source inverter --- the reactive power output can be dynamically and continuously adjusted to meet the power factor compensation requirements to the maximum, and the power factor at any time reaches 0.98~1.0.

2. Inductive / capacitive two-way adjustable --- Static Var Generator (SVG) does not need to configure a filter branch. Since no filtering is required, the SVG capacitor bank can be expanded or modified at any time to meet the new demands of possible operating conditions.

3. It does not need to increase the filter branch, it has the function of filtering harmonics --- STATCOM has the ability to control background harmonics of 19 times and below without increasing the filter branch.

4. Dynamic compensator has the smallest footprint.

5. Controllable current source--- SVG grid generator is a direct current control, the current output can be limited, no resonance occurs, and safety is high. TSC and TCR are impedance type devices. During long-term operation, system operation changes, reactors, and capacitor parameters change, which can easily lead to harmonic amplification and affect system safety.

6. Responding speed is 5ms --- The fastest response, with super reactive power compensation and harmonic filtering. Power SVG uses a new power electronics IGBT with a break time of less than 2us. The TSC and TCR are controlled by a thyristor with a switching time of 10ms, which is approximately 5,000 times that of an IGBT.

7. Loss is 0.5~0.8% --- The SVG grid generator has low operating loss, mainly due to the connection of reactors and IGBT losses, and the operating loss of the complete unit does not exceed 0.8%. In SVC, only the phase-controlled reactor has a loss of 0.9~1%, plus the thyristor and filter branch losses, the total loss is at least 1.2%.

8. Direct control of output current stepless regulation --- The generator SVG output reactive power compensation current does not decrease with the bus voltage drop, so that the dynamic compensation and voltage stability control capability of the same capacity SVG is 1.2 times or more of the same capacity TSC or TCR.

9. There are no phase-controlled reactors and magnetron reactors, and the harmonic characteristics are good. The noise of static device is smaller than TSC and TCR.

10. STATCOM in power system has high reliability and low maintenance.
