Aiming at the requirement for monitoring and controlling information in Smart Grid, the applications of ZigBee technology for Smart Grid were analyzed. After ZigBee technology and its features for Smart Grid were introduced, the prospects of ZigBee applications for Smart Grid were discussed in the cases of ZigBee applications in Smart Grid HAN, fault(More)
How to design a efficient routing among a set of mobile hosts (also called nodes) is one of the most important functions in ad hoc wireless networks. Routing based on a minimum connected dominating set (MCDS) is a promising approach, where the search space for a route is reduced to nodes in the set (also called gateway nodes). So, to determine this set is a(More)
Two kinds of BMA (Blind Mate A) connector for RFID (Radio Frequency Identification) system, which works at 5.8GHz, is investigated in this paper. The BMA connectors are modeled and simulated in HFSS (High Frequency Structure Simulator). By analyzing the simulation results, three specific steps are adopted to optimize and improve the performance of the RF(More)
Dynamic event region detection is an important application of wireless sensor networks. The position of event region should be transmitted to the base station in good time. A routing scheme based on gradient field and cluster is advised to track dynamic event region. The gradient field is set up after sensors are deployed. Only the event sensors are(More)
A novel approach for adaptive estimation of instantaneous harmonic currents in the power system is proposed in this paper. The signal processing technique based on Hopfield neural network (HNN) optimum theory is applied for the detection of harmonic components generated by nonlinear current loads. Instead of training the network, the basic principle of(More)
A shunt hybrid active power filter (APF) as harmonic generator taken to the DC link of the inverter eliminates harmonic wave generated by the inverter in this paper. Control is mixed by fuzzy logic control and hysteresis control and uses the digital signal processor. The value of DC-link inductance in the APF kept invariableness by this method, which made(More)
