A propos de cet article

nach der Bestellung gedruckt Neuware - Printed after ordering - Adistribution system suffers from current as well as voltage-related power-quality (PQ) problems, which include poor power factor, distorted source current, and voltage disturbances. A DSTATCOM, connected at the point of common coupling (PCC), has been utilized to mitigate both types of PQ problems. When operating in current control mode (CCM), it injects reactive and harmonic components of load currents to make source currents balanced, sinusoidal, and in phase with the PCC voltages. In voltage-control mode (VCM), the DSTATCOM regulates PCCvoltage at a reference value to protect critical loads from voltagedisturbances, such as sag, swell, and unbalances. However, the advantages of CCM and VCM cannot be achieved simultaneously with one active filter device, since two modes are independent of each other. In CCM operation, the DSTATCOM cannot compensate for voltage disturbances. Hence, CCMoperation of DSTATCOMisnot useful under voltage disturbances, which is a major disadvantage of this mode of operation.

Synopsis

Adistribution system suffers from current as well as voltage-related power-quality (PQ) problems, which include poor power factor, distorted source current, and voltage disturbances. A DSTATCOM, connected at the point of common coupling (PCC), has been utilized to mitigate both types of PQ problems. When operating in current control mode (CCM), it injects reactive and harmonic components of load currents to make source currents balanced, sinusoidal, and in phase with the PCC voltages. In voltage-control mode (VCM), the DSTATCOM regulates PCCvoltage at a reference value to protect critical loads from voltagedisturbances, such as sag, swell, and unbalances. However, the advantages of CCM and VCM cannot be achieved simultaneously with one active filter device, since two modes are independent of each other. In CCM operation, the DSTATCOM cannot compensate for voltage disturbances. Hence, CCMoperation of DSTATCOMisnot useful under voltage disturbances, which is a major disadvantage of this mode of operation.
