How does Static var generator reduce kva demand?

A Static Var Generator (SVG) reduces kVA demand through the following mechanisms:

1. Dynamic Reactive Power Compensation

• Real-Time Adjustment: SVG provide real-time reactive power support by injecting or absorbing reactive power (kVAR) as needed. This dynamic response helps maintain voltage levels, reducing the overall kVA demand.

2. Improved Power Factor

• Higher Power Factor: By compensating for reactive power, SVGs enhance the power factor of the electrical system. A higher power factor means that less apparent power (kVA) is needed to supply the same amount of active power (kW), effectively lowering kVA demand.

3. Minimized Reactive Power Draw

• Reduction in Utility Charges: By supplying reactive power locally, Static Var Generator decrease the amount of reactive power drawn from the grid. This reduces the kVA demand on the utility, which can lead to lower demand charges on electricity bills.

4. Stabilization of Voltage Levels

• Voltage Control: By stabilizing voltage, SVGs prevent voltage drops that can lead to increased current draw from the source. This stabilization helps maintain efficient operation and reduces unnecessary increases in kVA demand.

5. Mitigation of Harmonics

• Cleaner Power Quality: SVGs also help mitigate harmonic distortion, which can increase current and, consequently, kVA demand. By ensuring cleaner power, SVGs maintain lower kVA requirements.

By providing dynamic reactive power compensation, improving power factor, and stabilizing voltage, Static Var Generators effectively reduce kVA demand in electrical systems, leading to enhanced efficiency and cost savings.
