The paper analyses a kind of technology and products of ideal and normal non-contact electromagnetism tap changer, poses the calculating formula of circulating current. It is easy to control with the project of normal tap changer technology, but in this case the transition resistances and reactors need to be used, and the circulating current will appear when the tap position is changed. It will lead...
The Internet traffic analysis is important to network management, and extracting the baseline traffic patterns is especially helpful for some significant network applications. In this paper, we study on the baseline problem of the traffic matrix satisfying a refined traffic matrix decomposition model, since this model extends the assumption of the baseline traffic component to characterize its smoothness,...
Due to the transmission speed limitation of MIL-STD-1553B, no support for large data transmission especially, many departments have tried to improve the MIL-STD-1553B protocol. On this background, it is a necessity to develop a flexible and scalable simulation system to meet the demands of validating the improved protocol. Based on multi-thread technique, this paper designs an integrated MIL-STD-1553B...
The purpose of this research is study inverter simulation design for small wind power system. Through the comparative analysis, the main circuit choose high-frequency transformer form and using instantaneous voltage feedback control as control circuit. Using MATLAB software established a wind turbine inverter system circuit model, and gives out the circuit based on SPWM voltage feedback control system...
On the basis of the basic research in cognitive informatics, particularly the development of concept algebra, real-time process algebra (RTPA), the layered reference model of the brain (LRMB), and the object-attribute-relation (OAR) model for internal knowledge representation, the revilement of the cognitive process of learning and formal knowledge manipulation are enabled. This paper presents an...
