4 SIGUARD PSA - Protection Security Assessment Use Case and Workflow for Check of Protection Selectivity Optimized system-wide protection coordination Increased system security Higher system utilization Adherence to technical, safety and regulatory standards The high degree of automation enables the efficient handling of complex tasks, and helps saving time and resources SIGUARD PSA protection security assessment software and consulting services help ensuring reliable protection operation and system security Scenario builder Automated systemwide protection simulation In-depth fault clearing sequence evaluation Concise result visualization Weak spot identification by traffic light colors Selectivity and impact analysis Page 4

5 SIGUARD WAPC Wide Area Protection and Control Example of Recent Blackout in May 22, 2013, Vietnam Allows for fast detection of faults via PMU streaming analysis and consequently fast response in case blackout is expected. Response time of lower than one second are only possible with automation. Coordinated response however requires central knowledge. Combining the extreme high speed streaming analysis with the precalculated central stability assessment allows for punctual remedial actions like exact load shedding in the first second after the fault May 22, 2013, 14:00 High load situation 19,800 MW 1 major 500 kv line lost About 9.4 GW, 22 provinces and 8 million customers lost Nine hours until system restoration Frequency dependent load shedding too slow Dynamic process irreversible Point of no return reached 1.5 sec Blackout area Page 5
