SYNCHRONIZED MEASUREMENT MESSAGE RATE AFFECTS THE AGSS OPERATING TIME. MESSAGE RATES OF 10 OR 20 MESSAGES PER SECOND IS STILL VERY GOOD TO AVOID TRANSIENT STABILITY PROBLEMS IN THE REGION. CONCLUSIONS RECORDS OF ANGLE DIFFERENCE MEASUREMENTS FOR SINGLE LINE CONTINGENCIES VALIDATE MEASUREMENTS AND SIMULATION MODELS. AGSS MUST OPERATE ONLY WHEN TWO PARALLEL LINES ARE LOST IN SIMULTANEOUS OR SEQUENTIAL FORM
