Fresh photoelectron self-developed low-voltage dynamic reactive power compensation and harmonic treatment devices (hereinafter referred to as the SVG), using intelligent control algorithm, can fast reactive power compensation, harmonic filtering, suppress voltage fluctuation and flicker, and can effectively restrain three-phase imbalance, can very good to solve power quality problems of the power supply system.
Low-voltage dynamic reactive power compensation and harmonic control device (hereinafter referred to as SVG), using intelligent algorithm for control, can quickly compensate reactive power, filter out harmonics, inhibit voltage fluctuation and flicker, and can effectively suppress three-phase imbalance, can well solve the power quality problems existing in the power supply system.
Working principle: FGSVG series products of basic principle is to use can be shut off power electronics device (IGBT) since the commutation bridge type circuit, through the transformer or reactor in parallel to the grid, properly adjust the bridge circuit of ac output voltage amplitude and phase, or direct control of the ac current, make the circuit absorption or meet the requirements of reactive current, achieve the goal of dynamic reactive power compensation.
● Using three level structure, can reduce the voltage stress of single IGBT, reduce du/dt, improve the quality of output waveform.
● Using LCL filter circuit, can effectively absorb high frequency harmonics.
● Quick response speed, full response time is about 10ms.
● The use of international well-known manufacturers devices to build hardware platform, effectively ensure product quality.
● Analog sampling design accuracy is high, higher than 0.5%.
● Modular design, easy to install and debug.
● Rainproof and dustproof design, to meet the outdoor installation requirements.
● Can realize remote monitoring, real-time monitoring of power quality of power supply system.
● Safe and stable operation.
● With fault elimination and self-start function.
● Some models use puncture clip and open type outdoor CT, allowing electric installation.
