Active series compensated voltage regulator AVR series

Product Overview:

The AVR series active series compensation AC voltage regulator adopts the current new AC voltage regulator circuit topology, which has no mechanical contacts, stepless continuous adjustment, fast and high-precision

The characteristics of stable voltage output. It is an ideal alternative product for upgrading and replacing commonly used mechanical voltage regulators and thyristor regulated voltage regulators. Can be based on the customer

Personalized special design and manufacturing are required. The overall protection level of the outdoor fully sealed anti-corrosion active series compensation stabilized power supply device reaches IP65, meeting any harsh usage environment

Environmental requirements and certification.

Product Features:

Adopting current power electronic inverter technology to achieve fast and high-precision voltage stabilization control of output voltage. The power capacity of an active inverter system is only the power capacity of the compensating voltage,

The power capacity of the Wenle power supply can easily achieve a super large power capacity of ten megawatts, and can meet the high voltage regulation power supply requirements of any voltage level above 10KV. supplement

The compensation transformer is connected in series between the dry input power supply and the electrical load, and there will be no power outage when the inverter system fails, which can achieve continuous and uninterrupted power supply for angular loads. To lose weight

Compensate for the impact of transformer series voltage drop in the event of a few inverter failures, and bypass the bidirectional thyristor in parallel with the compensating transformer to quickly bypass when the inverter system fails

Compensation transformer, bypass conduction time ≤ 10us, while the bypass switch is closed within 30ms, and the inverter switch QF and KM contactor are also disconnected within 30ms, achieving seamless operation

The conversion between new stabilized power supply and bypass power supply.

By optimizing the design of the inverter system, it is possible to achieve rapid compensation and adjustment of the comprehensive power quality such as reactive power density and harmonics of the input power supply, in addition to the backup voltage regulator power supply

In addition, it can also achieve comprehensive power quality control functions such as fast reactive power compensation and harmonic control. It is currently a high-performance and fully functional stabilized power supply circuit topology

Structure. Output voltage stabilization accuracy<1V (phase voltage), output voltage stabilization response time<30ms: output voltage waveform and other dry input voltage waveforms; (No additional waveform generated)

Distortion and slight sinusoidal improvement in the output voltage waveform compared to the input voltage waveform. ）Efficiency of stabilized power supply: ≥ 98% (100% load); Each phase can carry 100% unbalanced angular load,

The voltage imbalance of the parallel three-phase line is less than 2%: when the angular load suddenly increases or decreases by 100%, the stable time of the output voltage is less than 2 fundamental cycles, and the transient change range of the output voltage is ≤ ± 3%.
