The newest generation of computers uses parallelism to enhance processing rates. This new technology makes possible speed improvements of a factor of 10 to 50 over even the fastest of the serial computers. However, these high processing rates are achieved only when the full capacity of the computer to perform operations in parallel is utilized. EPRI research project RP-670 includes several tasks that investigate the degree to which the computations of dynamic stability analysis can be performed in parallel. Both transient stability and small signal stability are considered. The transient stability problem is studied in significantly greater detail than the small signal stability problem. After a preliminary feasibility study produced positive results, the most computationally intensive part of a (simplified) transient stability program was coded and tested on the Floating Point Systems AP-120B. The code ran 82 times faster than a similar code running on an IBM 370/168.
