TSF Dynamic Harmonic Filters
INTRODUCTION：
With the development of science and technology, the variety and quality of non-linear electric facilities in industrial enterprises are increasing rapidly. These facilities produces large amount of harmonic at working, which increases the system loss and damage of the system. So how to eliminate this harmonic pollution has become an important international subject.
TSF-dynamic harmonic filters adopt the SCR auto-switch harmonic filters cooperating with the harmonic load, filtrate dynamic harmonic waveform and compensate dynamically the reactive power. This technique fills the national gap, has internationally advanced level.。
MAIN HAMONIC SOURCES：
◆Frequency converter, soft switch device
◆Arc stove, SCR rectification device
◆Electrified railway
◆Economic light, housekeeping appliance
◆Welding machine
HARMONIC HARM：
◆Reduce power generating, transmitting, and efficiency of the equipments
◆Threat the electrification equipment regular working
◆Cause local series and parallel resonance at the power grids
◆Cause the reactive compensating capacitor over-load
◆Cause the relay safeguard and automatic equipment error
◆Disturb the communicating system
◆Cause data loss and model burning down in the data controlling equipments
BASIC THEORY OF TSF DYNAMIC HARMONIC FILTERS：
Usually the harmonic current is proportional to the working current of the harmonic sources. TSF-dynamic harmonic filter measures the load harmonic currents through the controller and makes the bi-directional triode thyristor trigger at zero without shock, fluctuating current, and transitional process in the actuation process.
Additionally, TSF+TSC can consist into dynamic harmonic, reactive power multi-compensator, suitable to high-harmonic loads, low power factor and high fluctuating loads. It can effectively eliminate the dynamic harmonic and compensate the reactive power. TSF+TSC is an important innovation in the field of harmonic eliminating and reactive power compensating.
