Dynamic Voltage Regulator

Dynamic voltage regulator in series with the power distribution system is equivalent to a dynamically controlled voltage source, the use of appropriate control method can make the output offset voltage source power system disturbances such as voltage sags, voltage unbalance and harmonics of the load voltage caused by adverse effects.
When the DC side of the rectifier to obtain energy through from the system when the system side even in the event of single-phase fault, the other two phases can still provide  mcb circuit breaker to maintain the dynamic voltage regulator for normal operation, the voltage drop compensation for the long-term is also possible. If the DC capacitor in parallel across the battery, or the use of large-capacity energy storage capacitors, the device can also play the role of dynamic voltage regulator, circuit breakers  on the system side short-term failures can provide some time to load power. The use of appropriate topology, dynamic voltage regulator in the comprehensive management of the distribution system quality issues, such as dynamic voltage drops, surges and steady-state voltage quality problems (harmonics, fluctuation, phase imbalance, etc.), is a multi-objective voltage quality comprehensive management devices.
In addition, the distribution system power quality control technology and  mcb circuit breaker power supply, unified power quality controllers, solid state switches, distributed generation systems.
With the development of high-tech industries, information technology applications in all areas of society, power quality problem has aroused wide concern. Achieve power generation, transmission, distribution, consumption, customer, sales of electricity grid hierarchical scheduling, and comprehensive services the whole process of intelligent power industry, information technology, classification of the interaction will be the future grid management to improve the quality trends.
