Study on Optimization of Dynamic Characteristics of Turbo Generator Foundation

Article Preview

Abstract:

The dynamic characteristics of turbo generator foundation have an important impact on safe operation of power plant. The study first used the vibration mode superposition method to solve the structural vibration response and sensitivity through establishing the dynamic equations and optimization model of the foundation, and then determined the optimization variables, constraints and objectives according to the process conditions, and at last undertook multivariate optimization research on a 1000MW turbo-generator foundation. Finally, an optimization scheme which reduces both the linear displacement of foundation vibration and the amount of concrete used was obtained. The analysis results showed that the optimization method adopted in this study had higher efficiency and could achieve better technical and economic benefits.
