dc.description.abstractPOWER SYSTEMS ARE COMPLEX AND OFTEN SUBJECT TO FAULTS, REQUIRING ACCURATE MATHEMATICAL MODELS FOR A THOROUGH ANALYSIS. TRADITIONAL TIME-DOMAIN MODELS ARE EMPLOYED TO EVALUATE THE DYNAMIC RESPONSE OF POWER SYSTEM ELEMENTS DURING TRANSMISSION SYSTEM FAULTS. HOWEVER, ONLY THE POSITIVE SEQUENCE COMPONENTS ARE CONSIDERED FOR UNBALANCED FAULTS, SO THE SMALL-SIGNAL STABILITY ANALYSIS IS NO LONGER ACCURATE WHEN ASSUMING BALANCED CONDITIONS FOR ASYMMETRICAL FAULTS. THE DYNAMIC PHASOR APPROACH EXTENDS TRADITIONAL MODELS BY REPRESENTING SYNCHRONOUS MACHINES WITH HARMONIC SEQUENCE COMPONENTS, MAKING IT SUITABLE FOR AN UNBALANCED CONDITION ANALYSIS AND REVEALING DYNAMIC COUPLINGS NOT EVIDENT IN CONVENTIONAL METHODS. BY MODELING ELECTRICAL AND MECHANICAL EQUATIONS WITH HARMONIC SEQUENCE COMPONENTS, THE STUDY IMPLEMENTS AN EIGENVALUE SENSITIVITY ANALYSIS AND PARTICIPATION FACTOR ANALYSIS TO IDENTIFY THE VARIABLE WITH SIGNIFICANT PARTICIPATION IN THE CRITICAL MODES AND CONSEQUENTLY IN THE DYNAMIC RESPONSE OF SYNCHRONOUS MACHINES DURING ASYMMETRIC FAULTS, THEREBY CONTROL STRATEGIES CAN BE PROPOSED TO IMPROVE SYSTEM STABILITY. THE ARTICLE VALIDATES THE DYNAMIC PHASOR MODEL THROUGH SIMULATIONS OF A SINGLE-PHASE SHORT CIRCUIT, DEMONSTRATING ITS ACCURACY AND EFFECTIVENESS IN REPRESENTING THE TRANSIENT AND DYNAMIC BEHAVIOR OF SYNCHRONOUS MACHINES, AND CORRECTLY IDENTIFIES THE HARMONIC SEQUENCE COMPONENT WITH SIGNIFICANT PARTICIPATION IN THE CRITICAL MODES IDENTIFIED BY THE EIGENVALUE SENSITIVITY TO THE ROTOR ANGULAR VELOCITY AND ROTOR ANGLE.
