Eigenvalue and frequency-domain analysis of the intermountain power project and the wscc network
The Western Systems Coordinating Council (WSCC) has several interarea modes of oscillation in the range of 0.3 to 0.8 Hz. The results of an investigation of how various network parameters and operating conditions affect the stability of those modes are presented. Eigenvalue and frequency-domain techniques are used. The study results show that numerous system parameters can have a significant impact on overall network stability. These parameters can include control settings, such as those in HVDC systems or power system stabilizers, or operational parameters, such as scheduled tie-line flows. The results show that careful analysis and tuning of all significant controls in a large network are necessary to ensure overall system stability and satisfactory performance. >
Dynamic oscillations predicted by computer studies
During the latter part of 1988, a study was begun to review the dynamic stability performance of Georgia Power Company's Plant Scherer. The scope of the study was to identify any operating conditions that might contribute to system oscillations and to examine alternative solutions that would control these oscillations. The study was performed in several phases. The authors briefly discuss the study process which utilized two different software packages for the analysis: dynamic stability studies using time-domain software and eigenvalue analysis using frequency-domain software.<<ETX>>
