In this paper, an interruption simulation model for 252kV Self-blast SF6 circuit breaker is built according to the MHD theory, using real gas model and dynamic mesh method. Aiming at acquiring the characteristics and the differences of interruption under different power frequency, the gas flow field at different power frequency 50Hz and 60Hz are simulated and compared. Seven analysis points at the...
In this study, we proposed a controller design method of a two wheeled self-balancing vehicle (TWSBV) based on a fuzzy T-S model (T-S Fuzzy) associated with a genetic algorithm (GA). To achieve the stable controller of TWSBV, we used GA to determine the proper state feedback gains and used the T-S Fuzzy formed by the heuristic experiment with two fuzzy membership functions: vehicle body angle and...
An indefinite region disaster simulation model is established, in which model, a computational grid simplification model is proposed, human-computer interaction and cellular automaton technologies are adopted to deal with the closing boundary problems, fine feasibility of the disaster simulation model is verified by experiments.
The 21st century is the information age, along with the development of network technology and e-commerce, online shopping gradually replacing the traditional mode of shopping and become a new channel. How to stand out in many sites, how to attract online consumers to produce buying behavior? All these requirements need the e-marketing support. Thus, social traditional and material marketing model...
The traditional power droop controllers are commonly used in distributed generation (DG) units to share the loads among the parallel inverters. However, the parameters of the power transmission and distribution line in microgrid are small and generally presented high resistance-to-inductance (R/X) ratio which will seriously influence the performance of the traditional power droop controller, even...
