Description
Overview
GAOTek Comprehensive Power Quality Management directly connects the three-phase bridge inverter circuit to the power grid through a reactor, and appropriately adjusts the phase and amplitude of the output voltage on the AC side of the bridge circuit or directly control its AC side. The current can make the circuit emit reactive current that meets the requirements to meet the purpose of system reactive power compensation. Real-time tracking of system reactive power changes, linear compensation, to ensure that the system power factor is always maintained at 0.99, capacitive and sensitive two-way reactive power compensation range, according to the system reactive power changes, real-time adjustment, to ensure that the system does not appear over and under compensation problems Active compensation output to avoid problems such as resonance, harmonic amplification, and low voltage compensation efficiency that are common in traditional reactive power compensation equipment. It adopts modular design, simple expansion and maintenance, convenient wiring, flexible configuration, and convenient installation. It supports wall-mounted and rack-mounted installation, which can adapt to different site requirements.
Features
- Wide compensation range, (+1) to (-1)
- Fast response speed, full compensation response speed ≤ 10 ms
- Low-order harmonic compensation capability, can perform 3 to 13th harmonic compensation
- Three-phase unbalance compensation capability, which can adjust the three-phase imbalance of the system
- Flexible configuration, according to the actual power quality status of the system, set governance priorities to maximize module utilization
- Connected to the system in parallel, with 16 kinds of protection functions at the same time, comprehensive protection of equipment security and system security
- Flexible expansion, combined with common reactive compensation capacitor cabinet for hybrid compensation
