For the power quality improvement of the system FACTS devices like static synchronous compensator (STATCOM), static synchronous series compensator(SSSC), interline power flow controller (IPFC), and unified power flow controller (UPFC) etc. are introduced. These devices are used for the transmission system. But now a day’s these FACTS devices are used for distribution system and called as custom...

The Quality of the output power from the utilities has become a major concern of the modern industries. These power quality associated problems are voltage sag, surge, flicker, voltage imbalance, interruptions and harmonic problems. These power quality problems may cause problems to the industries ranging from malfunctioning of equipment to complete plant shut down. It has been identified that ...

The project deals with Minimum VA rating handled by a Unified Power Quality Conditioner, which consists of Series and Shunt Active Power Filter. The Series Active Filter is Dynamic Voltage Restorer (DVR), which regulates the voltage at the point of common coupling with minimum VA loading. The Shunt Active Filter is Distribution Static Compensator (DSTATCOM) which compensates the reactive power ...

This paper presents an advanced dynamic voltage restorer with integrated energy optimal compensation (EOC-DVR), which combines the advantages of pre-sag and minimization compensation. The performance parameters EOC-DVR, such as compensatory capability, loss energy, duration compensation, can be balanced by this strategy. Additionally, impact on load is further reduced proposed method. By analyz...
