Product overview

L - HTS800A product is set reactive power compensation and harmonic management is a body comprehensive products. This product is focused on harmonic management, for 1 ~ 50 times harmonic have very good management effect.
Applicable occasions: the harmonic quality requirement strict place, but with L - HTS800S combination to use, in order to achieve a more cover restrain harmonic and dynamic reactive power compensation effect.

operating principle

Active Power Filter (APF: Active Power Filter) to parallel way off the grid, real-time monitoring of Power grids generated by nonlinear load current waveform, filtering the fundamental wave part, and the remaining part of the reverse phase, again through the IGBT converter will reverse phase current injection to Power grid, so as to realize inhibition harmonic, dynamic compensation reactive functions, is the electric Power side harmonic management of excellent solutions.

Product Features

Filtering current harmonic
Based on the instantaneous reactive power theory of the harmonic current detection technology, real-time detecting harmonic current. Can cover the effect the filtering load current in 2 ~ 25 times every harmonic, the cover can be up to 50 harmonics, meet the requirement of national standard for distribution network harmonic. Can automatic identification load overall change and load harmonic content change and rapid tracking compensation, 40 us response load change, 20 ms realize completely tracking compensation.
Inhibition grid resonance
Compensation performance from the influence of system impedance, can eliminate and system impedance resonance risk. Can also be used to inhibit power supply system for harmonic cause system resonance.
Improve system imbalance almost
Can eliminate skin because of the impact caused by the system in the equipment capacity most situations, we can according to customer set compensation system base wave negative sequence and zero sequence unbalanced component and moderate compensating reactive power. In ensure filter based on the harmonic function can improve the system imbalance.
DSP smart surveillance
DSP high speed detection and operation, ensure harmonic detection and compensation control precision effectively; Both intelligent monitoring function, the device control flexibility, operation parameters, work condition be clear at a glance, automatic fault diagnosis; With remote communication interface, which can be through the PC machine real-time monitoring.
