Voltage Quality Improvement using Dynamic Voltage Restorer
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...
متن کاملOptimized Fuzzy Controller Design in Unbalanced Voltage Drop Mode for Dynamic Voltage Restorer
The loss of balanced voltages involves a voltage drop due to symmetric three-phase errors, or the initiation of high-power three-phase loads or symmetric three-phase switches. While these events in an unbalanced way lead to asymmetric voltage drops. Voltage drops can cause asymmetric load on the power grid, the occurrence of volatility, and even network power outage. One of the most common ways...
متن کاملDynamic Voltage Restorer for Voltage Sag Compensation Using Fuzzy Pi Controller
One of the major concerns in electricity industry today is power quality. It becomes especially important with the introduction of advanced and complicated devices, whose performance is very sensitive to the quality of power supply. The electronic devices are very sensitive to disturbances and thus industrial loads become less tolerant to power quality problems such as voltage dips, voltage sag...
متن کاملMitigation Of Voltage Sags/Swells By Dynamic Voltage Restorer Using Pi And Fuzzy Logic Controller
Dynamic Voltage Restorer can provide the most cost effective solution to mitigate voltage sags and swells by establishing the proper voltage quality level that is required by customer. This device is connected in series with the distribution feeder at medium voltage. The PI controller is very common in the control of DVRs. However, one disadvantage of this conventional controller is the fact th...
متن کاملVoltage profile improvement through online dynamic voltage restorer controlled by chaos-based genetic algorithm
Improving reliability indices, increasing the grid production capacity, reducing power loss during peak periods and fuel cost, and economic and environmental considerations on the one hand, and the progresses made in the field of semiconductor devices on the other hand, are some of the factors that increase the penetration of the renewable energy sources to the distributed network. When the pho...
