The main job for this year is to discuss the low-frequency oscillation situation of Taiwan power system in year 2003 and 2006 and propose appropriate advice and improvement methods. Now the discussion of that portion of year 2003 has been completed and that of year 2006 is expected to be finished until the end of this study year. The software needed includes PSS/E of PTI and SSSP of EPRI. If there is any kind of equipment model that is required but not included in the software package, the user-defined model such as the exciter user-defined model must be created. After solving all the modeling problems, observe the low-frequency oscillation situation of the system with and without power system stabilizers (PSSs) between 0 and 3 Hz first. Then use eigenvalues and right eigenvectors to determine the oscillation modes and examine the participation factors of those participating units with power system stabilizers to see if it is necessary to install PSSs on those participating units. The above analysis results need to be verified by time-domain analysis. If any oscillation mode with damping ratio not larger than 0.05 is discovered, solution will be addressed according to the specific situation of each mode, involving the decision of whether it’s necessary to install new PSSs or not to make the dynamic stability of the entire Taiwan power system meet the requirements. |
