Recent，The academic monographs of Ye Hua and Professor Liu Yutian at the School of Electrical Engineering "Large -scale Small Power System Features Calculation (Second Edition)" was published by Science Press。Supreme Monaste by Academician Cheng Shijie Preface，Basic Chapter、Method Article、Test and Application Articles，A total of more than 700,000 words。

Time stasis generally exists in the circuit、optical、neural network、Biological Environment、Dynamic system in the fields of machinery and other fields，The power system as the most complicated artificial system on the earth is no exception。Time stagnation in the power system，The introduction of the measuring element and the inherent characteristics of the control and execution components，It is an important factor that causes the performance of the controller to deteriorate and the system is unstable。But，8173_8185，Accurate modeling and efficient stability analysis of it faces huge challenges。At the same time，The application scenario of the power system makes the adaptability at scale、The accuracy of calculation and the efficiency of analysis are proposed.。

For this，Spense Focus on the accurate and efficient calculation of key science issues of the characteristics of the post -time stagnation system，systematically discussed the theory of characteristic value calculation of the eigencies of stagnation based on the large -scale when spectrum and dispersing,、Key technology and series algorithms，Including spectrum mapping、spectrum separation、spectrum change、Estimation of spectrum estimation and quadruple parts，Solving the feasibility problem of accurate calculation of the characteristic value of the time stagnation power system，Breaking the computing efficiency bottleneck of the characteristics of the characteristics of the stagnation power system when the large -scale large -scale large -scale large -scale level is large -scale。Relying on monographs，Developed the first international stagnation power system feature value calculation commercial software SSAP-Peigd，Processing scale、accuracy、Efficiency and other indicators internationally lead，The basic tool for becoming the stability analysis of the power system; support the "key technologies and applications and applications of control analysis and control of the stagnation power system" in 2021, the second prize of scientific and technological progress in Shandong Province。
