Mitigation of Voltage Sags/swells Using Dynamic Voltage Restorer (dvr)
This paper describes the effectiveness of using dynamic voltage restorer (DVR) in order to mitigate voltage sags and swells in low voltage distribution systems. A dynamic voltage restorer based on the dqo algorithm is discussed. The proposed control scheme is very effective to detect any disturbance in low voltage distribution systems. Simulation results using Matlab/Simulink are presented to v...
متن کاملStochastic Assessment of Voltage Sags in Distribution Networks
This paper compares fault position and Monte Carlo methods as the most common methods in stochastic assessment of voltage sags. To compare their abilities, symmetrical and unsymmetrical faults with different probability distribution of fault positions along the lines are applied in a test system. The voltage sag magnitude in different nodes of test system is calculated. The problem with the...
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 Sags/Swells Mitigation Using a Dynamic Voltage Restorer Controlled by Neural Network
In this paper the effectiveness of a Dynamic Voltage Restorer controlled by neural network for voltage sags/swells mitigation is shown. A typical configuration of DVR is implemented by using MATLAB Simulink®, which is controlled using backpropagation neural networks. The good performance for voltage sags/swells mitigation of the DVR controlled with neural networks can be observed by means of se...
