【Abstract】 The influences of model parameters based on actual measurement of excitation systems and generator model with constant E’q on Stability Calculation of Shandong Power Grid are researched,namely the influence of these factors on static stability,transient stability and dynamic stability of Shandong Power Grid.Taking the heavy load mode of Shandong Power Grid in the summer of the year 2008 as the base of calculation,the PSD-BPA stability calculation software and PSD-SSAP small signal calculation software developed by China Electric Power Research Institute are adopted in this research.Research results show that,the stability limit of Shandong Power Grid can be evidently heightened under the calculation using the model parameters based on actual measurements of excitation systems than that under the calculation using the generator model with constant E’q.The research finding shows that the operating economy of Shandong Power Grid can be effectively improved by rationally referring to the stability calculation results in which the model parameters based on actual measurements of excitation systems are utilized.更多还原
