| 1 | Power system low frequency oscillation monitoring and analysis based on multi-signal online identification显示文摘The advance in the wide-area measurement system (WAMS) is driving the power system to the trend of wide-area monitoring and control.The Prony method is usually used for low frequency oscillation online identification.However,the identified amplitude and phase information is not sufficiently used.In this paper,the amplitude is adopted to detect the occurrence of the oscillation and to obtain the mode observability of the sites.The phase is adopted to identify the oscillation generator grouping and to obtain the mode shapes.The time varying characteristics of low frequency oscillations are studied.The behaviors and the characters of low frequency oscillations are displayed by dynamic visual techniques.Demonstrations on the '11.9' low frequency oscillation of the Guizhou Power Grid substantiate the feasibility and the validation of the proposed methods. | YUAN Ye1,2,SUN YuanZhang2,CHENG Lin2,CHEN Gang2 & WANG Peng3 1 State Nuclear Electric Power Planning Design and Research Institute,Beijing 100032,China 2 State Key Laboratory of Power Systems,Deptment of Electrical Engineering,Tsinghua University,Beijing 100084,China 3 EEE School,Nanyang Technological University,Singapore | 2010 | Science China(Technological Sciences)2010，53，9： | 13 |
| 2 | THEORY AND NUMERICAL ANALYSIS OF THE INTERACTION BETWEEN TURBULENCE AND SUSPENDED SEDIMENT显示文摘The coupled hydrodynamical-ecological model for Regional and Shelf Seas Coherens was modified through introducing sediment model in order to simulate suspended sediment transport and account for the interaction between turbulence and sediment. To discuss the effects of sediment on vertical eddy viscosity and diffusion coefficients, the damping function of sediment on turbulence was introduced into one equation k-ε turbulence closure model. Moreover, it is assumed that local equilibrium among turbulence production, dissipation and buoyancy destruction exist near the bottom. The local equilibrium assumption is introduced into the one equation k-ε model and the specific formulation of local equilibrium for one equation k-ε was derived. The tidal current was calculated for Youngkwang Bay near the west coast of Korea. Meanwhile, the suspended sediment was also simulated with the local equilibrium assumption and damping function of sediment on turbulence. It is found that the damping function of sediment reduces vertical eddy viscosity and diffusion coefficients. The local equilibrium assumption changes obviously bottom layer turbulence intensity and sediment concentration. | LIANG Bing-chen EEE Dong-young LI Hua-jun LI Lei-yan | 2005 | Journal of Hydrodynamics2005，17，5： | 4 |
