Fast Transient Hybrid Neuro Fuzzy Controller for STATCOM During Unbalanced Voltage Sags
A static synchronous compensator (STATCOM) is generally used to regulate voltage and improve transient stability in transmission and distribution networks. This is achieved by controlling reactive power exchange between STATCOM and the grid. Unbalanced sags are the most common type of voltage sags in distribution networks. A static synchronous compensator (STATCOM) is generally used to maintain...
متن کاملUnbalanced Voltages and Electric Motors: Causes and Consequences
Unbalanced voltages are unequal voltage values on 3-phase circuits that can exist anywhere in a power distribution system. Unbalanced voltages can cause serious problems, particularly to motors and other inductive devices. Perfectly voltage-balanced circuits are not possible in the real world. However, assuming perfectly balanced voltages are possible, branch circuit voltages on a 480/277V supp...
متن کاملModelling and Analysis of STATCOM Based Voltage Regulator for Self-Excited Induction Generator with Unbalanced Loads
This paper presents an analysis of the three-phase self-excited induction generator (SEIG) with staticcompensator {STATCOM) as a voltage regulator. Current controlled voltage source inverter (CC-VSI) is used as STATCOM, which provides fast dynamic response to maintain constant voltage at SEIG terminals during severe load perturbations and acts as a source and sink of reactive power. The perform...
متن کاملActive Filter Control Method Based on Direct Power Control for Compensating Reactive Powers due to Unbalanced Voltages and Nonlinear Loads
Active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. This paper proposes a control scheme based on the instantaneous active and reactive power. The inverter of this active filter is a three-phase, two-level converter. Space vector technique is used as modulators and pattern genera...
متن کاملOperation of Stand Alone PV Generating System for Supplying Unbalanced AC Loads
This paper describes a DC isolated network which is fed with Distributed Generation (DG) from photovoltaic (PV) renewable sources for supplying unbalanced AC loads. The battery energy storage bank has been connected to the DC network via DC/DC converter to control the voltage of the network and optimize the operation of the PV generation units. The PV arrays are connected to the DC network ...
