The role of the SVG compensator in the static reactive power compensation scheme
Aug 14, 2025| In the power system, the SVG static var compensator, as a modern var power compensation device, plays a crucial role in the static var compensation scheme. And due to its dynamic response capability and high efficiency, the SVG compensator has become the preferred solution for many industrial and commercial applications. So, what is the role of the SVG compensator in the static var compensation scheme?

I. The Role of SVG Compensators in Static Reactive Power Compensation
In the static reactive power compensation scheme, the main function of the SVG compensator is to stabilize the voltage, improve the power factor, reduce the transmission of reactive power, and enhance the efficiency of the power system. The following are several key functions of the SVG compensator in static reactive power compensation:
Ⅰ.Improve power factor
1. Power factor is an important indicator in the power system. A low power factor will cause an increase in the burden on the power grid, lead to more energy waste, and may result in fines being imposed by the power company. The SVG compensator helps the power system maintain a higher power factor by dynamically adjusting reactive power, thereby improving the efficiency of energy usage.
2. Stabilize voltage fluctuations
Voltage fluctuations often occur when industrial loads undergo significant changes, especially in cases where high-power equipment is used. SVG compensators can quickly respond to changes in the load and adjust the compensation amount in real time to maintain the stability of the power system voltage and prevent equipment from malfunctioning or being damaged due to voltage fluctuations.
3. Reduce reactive power transmission
Traditional reactive power compensation devices such as capacitor banks can provide reactive power compensation, but their compensation capacity is usually fixed and cannot adapt to changes in load. SVG compensators, on the other hand, can flexibly adjust the compensation capacity according to the actual load requirements, reduce the transmission of reactive power, and thereby alleviate the burden on the power grid.
II. Working Principle of SVG Compensator
The working principle of the SVG compensator is based on power electronic technology. It achieves reactive power compensation by using a converter and a control system. During operation, the SVG compensator continuously detects the voltage and current waveforms in the power system, calculates the required reactive power to be compensated, and precisely controls the compensation amount by adjusting the on-off states of capacitors and reactors according to the system requirements. Its main advantages are fast response speed, real-time adjustment capability, and no need for pre-set compensation capacity.
Jinneng SVG Series Static Var Generator, as a crucial device in modern power systems, plays a significant role in static reactive power compensation schemes. It not only enhances the power factor, stabilizes the voltage, reduces the transmission of reactive power, but also responds in real time to load changes, ensuring the efficient and stable operation of the power system.
