The Study of SVC in Power System and Its Impact on Voltage Stability
A long-standing problem of our power grid construction and operation is lack of reactive power compensation capacity and is equipped with an unreasonable, especially the adjustable reactive power capacity, rapid response of less reactive power conditioning equipment. With the rapid development of power industry, high pressure, ultra high voltage power grids have been put into [...]
The Research on Property of Air-inflated Membrane Structure Based on the Fluid-structure Method
After nearly ten years of development, the basic theories of the tension structure have been available for a number of scientists, but for the air-inflated membrane structure there are some problems having not been resolved yet, such as static analysis, dynamic analysis and solid-fluid interaction analysis under wind load, the first two of which are [...]
Dynamic Analysis Methods of Large-sized Centrifugal Compressor Impeller
Impeller is the most important part of centrifugal compressor.It is not enough for the reliability design of impeller that only the centrifugal load is considered in the static analysis.The flow-solid interaction and the special dynamic behavior must be considered during the impeller analysis process.It is the key issue for the safety and reliability design of [...]
Numerical Simulation on Stability Analysis of Underground Caverns Surrounding Rock Mass
With the shortage of petroleum, the reserves for national strategic become more and more important. As a superior performance method underground water-sealed rock storage caverns must be common application in future. The excavation of large-scale underground rock storage caverns will be effect underground stress field. Researching and monitoring the stress and displacement of the caverns [...]
Research on Improved Calculation Method of Elasticity Factor of Highway Transportation Based on Dynamic Analysis of Transportation and Economy
Transportation is a foundational and service industry in national economy, and it is a key factor of the whole economic society. Meanwhile, as a crucial component of transportation, highway transportation holds the balance of it. Elasticity factor of highway transportation reflects the dependent relationship between the growth of highway transportation and economic society development. Accurate [...]
