Detailed Solution
Download Solution PDF- The critical clearance time of a fault is related to maximal fault duration for which the system remains transiently stable.
- Transient stability means the ability of a power system to experience a sudden change in generation, load, or system characteristics without a prolonged loss of synchronism.
- To maintain transient stability, a power system fault must be cleared quickly enough so that the fault on transient remains inside the stability boundary.
- The critical clearing time exceeds, stability is lost by generators using synchronism.
