This work demonstrates the use of digital simulation for analyzing protection
system performance. For studies of complex, multi-relay protection systems, digital simulation provides utility engineers with an attractive alternative to relay testing techniques. The cost of digital simulation facilities can be lower than the cost of comparable testing facilities; relay hardware does not have to be made available for the test laboratory.
Digital simulation would ordinarily be impractical for security and dependability studies, due to the thousands of individual simulations involved. The number of simulations needed can be greatly reduced by using a technique called "numerical logic replacement" for implementing the protection scheme logic. This unconventional technique makes near-misoperation visible from individual simulations.
The likelihood of overlooking potential misoperation is thus much lower than with the usual direct (Boolean) implementations. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate
