CoEpower Active Voltage Conditioner Overview

Voltage sag is a typical power quality problem that troublesindustrial enterprises. It may cause the malfunction of the deviceor tripping. For a voltage sag event, depth and duration are usedto describe it.

AVC is a solution designed by CoEpower for voltage sags and swells of up to 30% The AVC isconnected in series between the load and the power grid, and is responsible for stabilizing thevoltage downstream.

The CoEpower AVC Active Voltage Conditioner is an inverter-based system that protects sensitive industrial and commercial loads from voltage disturbances. يوفر بسرعة, دقة الجهد التراك وتصحيح الطفرة, وكذلك تنظيم الجهد المستمر وتعويض الجهد الحمل.

Application Cases of CoEpower Active Voltage Conditioner

Hospital Power Distribution

Medical imaging equipment in hospitals requires a continuous and stable power supply to ensure accurate and reliable operation. CoEpower AVC effectively stabilizes input voltage, protecting sensitive equipment and preventing interruptions that could impact diagnosis and patient care.

Production Line Power Distribution

Production lines rely on uninterrupted operation to maintain efficiency and product quality. CoEpower AVC ensures stable voltage supply, preventing equipment shutdowns, malfunctions, or collisions caused by voltage fluctuations, thereby improving overall productivity and safety.

Key Advantages and Features of CoEpower Active Voltage Conditioner

1. +30% Sag and Swell Continuous Compensation

The system provides continuous voltage regulation with a compensation range of up to ±30%, effectively mitigating voltage sags and swells in real time. This ensures a stable power supply for sensitive equipment such as PLCs, محركات الأقراص, and precision instruments, reducing the risk of unexpected shutdowns, data loss, or equipment damage. It is especially valuable in environments with unstable grid conditions or frequent load fluctuations.

2. Remote Monitoring and Controlling

Equipped with intelligent communication capabilities, the conditioner supports remote monitoring and control via SCADA systems or cloud-based platforms. Users can access real-time data, alarms, historical records, and system diagnostics from anywhere. This feature significantly improves operational visibility, enables faster troubleshooting, and reduces the need for on-site maintenance.

3. Harmonic Compensation

The device actively detects and suppresses harmonic distortions generated by non-linear loads such as inverters, أنظمة UPS, and variable frequency drives (VFDs). By reducing total harmonic distortion (THD), it improves overall power quality, prevents overheating of equipment, and extends the lifespan of transformers, الكابلات, والمكثفات.

4. Indoor and Outdoor Installation Flexibility

Designed with robust enclosure options, the system is suitable for both indoor and outdoor installations. Outdoor models are built to withstand harsh environmental conditions such as dust, رطوبة, and temperature variations, ensuring reliable performance in industrial plants, substations, and remote locations.

5. تعويض الطاقة التفاعلية

The conditioner dynamically compensates reactive power, improving the overall power factor of the system. This reduces energy losses, enhances electrical efficiency, and helps users avoid utility penalties associated with low power factor. It also contributes to better voltage stability across the network.

6. Current Unbalance Compensation

The system continuously monitors three-phase current conditions and automatically corrects unbalanced loads. By redistributing current evenly across phases, it minimizes neutral current, reduces equipment stress, and improves the overall reliability and efficiency of the power distribution system.

How Does an AVC Active Voltage Conditioner Work?

The working principle of an AVC Active Voltage Conditioner is based on real-time voltage compensation using advanced power electronics.

1. Continuous Voltage Monitoring

The AVC continuously monitors the incoming supply voltage using high-speed sensors. It detects any deviation from the preset nominal voltage.

2. Control System Analysis

A digital controller (typically DSP-based) analyzes the voltage deviation in milliseconds and determines the required correction.

3. Series Injection Transformer

The AVC uses a series injection transformer to add or subtract voltage from the supply line. This allows it to compensate for voltage sags or swells.

4. Power Electronics Converter

A high-speed inverter or converter generates the compensating voltage, which is then injected into the system.

5. Real-Time Compensation

The system responds within milliseconds, ensuring that the output voltage remains stable and within acceptable limits.
