Product Name : AVC SET DVR 150kVA 208V
Description
Optional: AVC SET DVR 300kVA 208V
AVC SET DVR: Advance Voltage Conditioner SET - Dynamic Voltage Restorer
Immunize industrial process from sag, overvoltage and regulation problems
Product Description and Advantage
The AVC SET DVR is an innovating system designed to mitigate sags or dips and overvoltage as well as regulations problems. The AVC SET DVR guarantees the quality of the grid, meeting the demands of industrial production processes, keeping stable and constant the output voltage regardless of input voltage variations. The AVC SET DVR is a flexible voltage compensator, injecting and absorbing energy, capable of correcting sags of 40% of input voltage, to offer a highly stable voltage (± 0.5 %) with immediate response (<3msec).It consists of a booster transformer, a reversible rectifier unit, plus an inverter. The aim of the AVC SET DVR is to offset disturbances, voltage imbalances, and to regulate them in case of possible fluctuations and overvoltage. The system also supervises controls and logs sag events. The output voltage stabilization is assured both for balanced (three phases) and unbalanced voltage variations. The AVC SET DVR offers an important advantage which is the lack of energy storage components leading to very low maintenance cost and maximum power supply availability. The following figure graphically illustrates its compensation method:
Because the energy flow could be reversed throughout the (booster) transformer in series with the line, the AVC SET DVR equipment achieves high efficiency as well some other advantages, namely:
Free of any energy storage components.
Longer time frame for repetitive dips events (10 to 15 seconds)
Allow continuous operation to offer very high voltage regulation accuracy.
Allow bi-directional energy flow.
Improve time response to allow permanent voltage distortion filtering.
The dynamic response of the AVC SET DVR is summarized in the following table:
Product Features and Technical Specifications
As mentioned before, the AVC SET DVR has been designed to immunize process and equipment requiring complying with SEMI F47 and is available in power capacities of 50 kVA to 4.2 MVA.
The Zigor Dynamic Voltage Restorer offers the following disturbances compensation capabilities:
Voltage dips and swells
Voltage variations
Voltage distortion
Voltage flicker
Voltage unbalance
Some level of transient over voltages
Complementary the AVC SET DVR system has the following main features:
- No battery or alternative energy storage required, minimizing maintenance cost and increasing reliability.
- Continuous voltage regulation within the ± 0.5%.
Compensation of deep long lasting dips (-50% up to 15 sec).
Avoids relays and brushes.
Time response less than 3 milliseconds.
Capable to operate with industrial regenerative loads (e.g. four-quadrant converter).
Improves the voltage distortion.
Non-stop of process operation in case of failure.
Easy to parallel additional equipment.
Independent phase compensation.
Balanced and unbalanced dip compensation.
Automatic Bypass
Efficiency 97.5% for LV and 98.5% for MV.
Overload capacity: 150% during 1 second.
Dips logging and system monitoring.
Due to the independent phase compensation capability as well as the bidirectional energy flow control operation, this equipment can balance and equalize three phase unbalanced systems, both during transients and continuously.
Its capability to respond for 2 to 3 m sec sub-cycle transients together with complementary TVSS equipped as standard offers a high level of overvoltage protection both for very fast and fast transients (e.g. capacitor’s bank switching).
The specs shown bellow correspond to the general specs for all the models. Low voltages models are designed for indoor use and medium voltage models could be build in steel or concrete containers for outdoor usage.
Different topologies for maintenance and redundancy are possible depending on the customer requirements. The size for the different models is presented in the next table (for model with nominal Voltage 400V).
Standard equipment does not include maintenance bypass nor protection elements that are normally defined by the customer on the project by project basis.
Low voltage models 208 to 480Vac are offered in an all-in-one cabinet with the booster transformer included. For MV systems, two options are available: full equipped container with and without the MV transformer and switchgears.
