Development and Application of Power Flow and Stability Analysis Platform Based on PSD-BPA

PSD-BPA calculation software is an essential tool for electric power planners.With the rapid development of China's power grid,the advance of smart grid and construction of UHV AC/DC transmission network,the setup of national network architecture has gradually formed.Owing to the single integrated application environment,low degree of intelligence,inefficient result application and other shortages of traditional PSD-BPA software,the efficiency of electric power planning and design is affected.In order to enhance computational tools and improve work efficiency,PSD-BPA based stability calculation of the power flow analysis platform using the RD results of the online pre-decision system is developed.A platform based on PSD-BPA is developed for grid power flow stability calculation and analysis with such new functions as the advanced power grid analyzing function to off-line platform,friendly man-machine interface,highly efficient power modeling,automatic multi-core parallel calculation,and intelligent auxiliary analysis of decision-making integrated into an organic whole.Wide engineering application shows that the analysis platform is user-friendly,intelligent and efficient with fast calculation and correct and effective decision support.
