Case study
One of the challenges to the operation of a large, interconnected power system is to ensure that the generators will remain in synchronism with one another following a large system disturbance such as the loss of a large generator or transmission line. Traditionally, such a stability assessment has been done by engineers performing lots of off-line studies using a variety of assumed system operating conditions.
But the actual system operating point never exactly matches the assumed system conditions. The following article discusses a newer method for doing such an assessment in near real-time using the actual system operating conditions.
CASE STUDY QUESTIONS
A. How is dynamic security assessment (DSA) software used in actual power system operations?
B. What techniques are used to decrease the time required to solve the DSA problem?
