This paper builds a reasonable and brief system model, which can be used for the power system stability simulation. This system model consists of the mathematical models of power units, their sub-control systems, the load and grid. Moreover, this paper established two Coordinated Control System (CCS) models with different logical configuration of the actual CCS and connected these CCS models to the...
Model simulations are becoming more important in dynamic power system analyses as our increasing dependence on electricity supply. However, the general steam models often show some disadvantages in dynamical cases. No enough attention is paid to the non-linear relationships between flow rate and pressure differences. The paper puts forwards a new nonlinear turbine model taking the nonlinearities into...
Fossil-fueled steam-electric power plants have many outstanding advantages and are still one of the main power types in the world especially for non-European countries. The classic mathematic models are designed for traditional hydraulic governing steam turbine units. Single turbine and its control system models are used wildly for dynamic analysis in power system. Digital electro-hydraulic (DEH)...
This paper presented a novel network model for dynamic stray capacitance calculation of planar inductor with matrix structure, of which the nanocrystal magnetic material was used to consist of its magnetic core. The magnetic core was taken into account to be one part of this dynamic capacitance network model in high frequency, and its electric potential was considered to be suspended. To calculate...
A social network consists of events and individuals, in which the events denote the activities happening in the system and the individuals denotes the peoples who are attracted into the activities. A memory feature exists in a dynamic social network which leads to the decay of the event attraction, and further influences the structure and the dynamics of the network. In the paper, an agent model for...
