Introduction

  • LSVG Static Var Generator is used as comprehensive power quality improvement for power distribution system transformers side, which have the functions of power compensation, harmonic control and three phase unbalance governance simultaneously. Compared with conventional capacitor compensation scheme, it is precise, two-way, fast reactive power compensation capabilities, and to eliminate the risk of capacitive system harmonics; Compared with the traditional SVG program, it can resolve the problem of harmonic and reactive power. It is equipped with high quality power factor controller SGC .

Feature

  • maintain receiving end voltage, strengthen system voltage stability
  • compensate system reactive power, improve power factor, reduce line loss, save energy and reduce cost
  • suppress voltage fluctuation and flicker
  • suppress three phase unbalance
  • compensate both inductive and capacitive loads to achieve PF0.99 and avoid less and over compensation Fast Response
  • Fast response is implemented by SVG modules.
  • The SVGs in the SVGC show the advantage of the electronic power switch. In the legacy SVC, the thyristor only serves as a fast switch, but cannot implement high-frequency
  • Optimal solution to reactive compensation and three-phase unbalanced compensation
  • Integrating general LC compensation with the latest SVG compensation technology
  • Integrated Control & Monitoring System (ICMS)with 18 I/O ports to implement flexible LC and SVG applications PF= 0.99, avoiding over-compensation and under-compensation

Model Selection Guide

  • The rated voltage and rated capacity of the device should be reflected in the order model, and other special requirements must be noted;
  • LSVG series static var generators have two structural modes: integrated cabinet type and modular combined cabinet type, which can be combined with all mainstream switch cabinet types of low voltage, and are suitable for different busbar fixing positions and methods
  • The device configuration and structure size can be negotiated according to user requirements.

Example:

  • If the rated voltage of a system is 0.4kV and it needs to compensate ±400kvar reactive power compensation, it is recommended to use a static var generator of model LSVG-0.4-400/4, using 4 100kvar modules, consisting of a cabinet, The size is 800×1000×2200mm.
