JL-TSVCG Series Hybrid Static Var Compensation System-Jiangsu Laibao Electric Power Co., Ltd.

JL-TSVCG Series Hybrid Static Var Compensation System

Product Overview

The JL-TSVCG series hybrid static var generator is a composite system comprising the JL2000-ST hybrid static var controller, Thyristor Switched Capacitors (TSC), and a Static Var Generator (SVG) developed in-house. The TSC unit consists of a dynamic compensation controller, reactors, and fixed capacitors, while the SVG is a fast-response static var compensation device centered on a power converter; together, they provide dynamic reactive power compensation and targeted harmonic filtering. The JL-TSVCG device combines the respective strengths of TSC and SVG technologies—an innovation independently developed by Jiangsu Laibao. It simultaneously addresses common power quality issues in distribution networks—such as substandard power factor, current imbalance, voltage flicker, and current harmonics—thereby improving power supply quality, ensuring the safe operation of user equipment, and enhancing energy efficiency.

Performance Features

By integrating the advantages of TSC dynamic compensation and SVG static var generation, the JL-TSVCG hybrid device achieves significantly optimized compensation precision and response speed while substantially reducing system costs. The JL-TSVCG provides smooth, dynamic, and rapid reactive power compensation across the full inductive-to-capacitive range. It features comprehensive harmonic suppression capabilities, a user-friendly Chinese-language touchscreen interface, and robust protection functions. With its stable performance, it is ideally suited for comprehensive power quality optimization in industrial environments.
