Types of SVC

• Centralized SVC
  Installed at the high-voltage busbar of a substation or distribution room, typically within the range of 6 kV–35 kV, to provide centralized reactive power compensation for the entire load. Currently, centralized SVC is widely adopted in domestic applications.
• Distributed SVC
  Installed close to large-scale impact or nonlinear loads (such as rectifiers or arc furnaces), providing localized compensation for specific loads. Distributed SVC reduces transformer burden, improves local voltage stability, and mitigates negative impacts of load fluctuations.

Key Features

• Fixed filter group design: Eliminates the need for switching with load variations, ensuring reliable filtering without additional switching losses.
• Automatic control: System parameters are adjusted automatically according to load variation, changing TCR trigger angles to regulate reactive power output.
• Fast response and high precision: Advanced DSP control technology ensures a response time of less than 10 ms with a regulation accuracy of ±0.1°.
• Optical fiber triggering: Centralized SVC uses advanced optical fiber triggering technology, reducing interference and improving anti-noise capability. With BOD (Break-Over Diode) tube technology, reliable triggering is achieved with rapid protection, ensuring safe operation under severe grid conditions.
• Flexible configuration: Capacitor and reactor groups can be flexibly configured to meet user-specific needs, ensuring stable and efficient operation.
• Improved power quality: Effectively suppresses voltage flicker, reduces harmonic distortion, balances three-phase loads, and enhances overall power factor.
