Intermediate pressure dynamic var compensation (DSHT-TSC)
Purpose: DSHT series dynamic reactive power compensation device uses world advanced thyristor technology. According to the system and load changes, use thyristor to constitute contactless AC switch to drive multi-capacitor for rapid and frequent switching and achieve no transition adjustment of the capacitor. Since the over-voltage and over-current in the process of switching are greatly reduced, the capacitor life is also greatly improved, and it is conducive to stable running of the system. The capacitor branch of DSHT series intermediate pressure dynamic reactive power compensation device is also connected to tuning reactor in series, which can effectively prevent harmonic amplification, absorb part of the harmonic currents, and suppress the harmonic.
DSHT is widely used in various industrial environments, with strong environmental adaptability and stability to meet the rapid changes in load, large impact, low power factor and other reactive power compensation requirements.
Features:
Short response time: quick switching speed, capacitor switching within 20ms
Superior compensation performance: automatically compensate and regulate reactive power according to the reactive power of the grid and voltage control requirements, improve system power factor and keep it higher than 0.95.
Advanced contactless electronic switch: use bi-directional inverting-parallel thyristor technology to achieve contactless electronic switch, zero voltage switching, no impact, no inrush current or overvoltage, no transients or harmonics, which will increase system stability and greatly extend the switch life.
Harmonic absorption and suppression: filter reactor in series ensures that not only harmonics is prevented, but also prevents harmonic amplification and absorbs some harmonic currents while compensating reactive power.
Voltage level: suitable for reactive power compensation for 3kV, 6kV, 10kV
Capacity: single intermediate pressure set up to 1350kvar
