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...

This paper presents the custom power devices to improve the power quality by using a Distribution Static Compensator (DSTATCOM). Custom power is a technology driven product and service solution which embraces a family devices such as DSTATCOM. It describes the techniques of correcting the supply voltage sag in a distribution system by DSTATCOM. The steady state performance of system with or wit...

The typical loads in the commercial buildings comprise of many single phase and three phase loads which includes non-linear loads. These loads are highly sensitive for any input variations in voltage. The performance of the electrical equipment gets worsened if they are supplied with polluted or distorted voltage. This paper presents modeling and analysis of custom power devices. SAPF based UPQ...

Power quality is one of major problems in the presence era. It has become importance especially, with the introduction of sophisticated devices, whose performance is very sensitive to quality of power supply. power quality problem is an occurrence manifested as a nonstandard voltage,current,or frequency that results in a failure of end use euipement.One of the major problem deal here is the vol...

Custom power is a technology driven product and service solution which embraces a family devices such as Dynamic Voltage Restorer (DVR), Distributed Shunt Compensator (DSTATCOM), Solid State Breaker (SSB) etc which will provide power quality functions at distribution voltages. The rapid response of these devices enables them to operate in real time, providing continuous and dynamic control of t...
