At present, voltage regulation of no load distribution transformer is not flexible and failure rate of mechanical on-load tap-changers is high. To solve these problems, a scheme of automatic on-load voltage regulation system designed via thyristor for distribution transformer was proposed. The system improved the existing topology of on-load voltage regulation system via power electronic device and...
Existing loop vectorization techniques can exploit either intra-or inter-iteration SIMD parallelism alone in a code region if one part of the region vectorized for one type of parallelism has data dependences (called mixed-parallelism-inhibiting dependences) on the other part of the region vectorized for the other type of parallelism. In this paper, we consider a class of loops that exhibit both types...
The present study analyzed the characteristics of switching overvoltage, and discussed in detail the main influencing factors and worst-case conditions of switching overvoltage in the 1100-kV ultra-high-voltage direct-current (UHVDC) converter station. The results showed that ac bus overvoltage was produced by oscillation, and would not be a threat to the equipment in the converter station....
PV Grid-connected is the development trend of solar system application, and grid-connected inverter is one of the key components in PV grid-connected systems. Based on DSP TMS320F2812, a 10 kW single-phase grid-connected inverter has been built in this paper. DC-DC Boost chopper structure circuit and full bridge inverter circuit are used in the system, with the functions of Maximum Power Point Tracking...
In this work, we consider a distributed link-weighted and distance-constrained channel assignment (DLDCA) algorithm for a multi-channel multi-hop mesh network, such as community wireless networks, to maximize its throughput. Efficient channel assignment could greatly reduce interference of each link from its neighboring links and subsequently improve the network throughput. In response to it, we introduce...
In this work, we study a link-weighted and distance-constrained channel assignment problem in multi-channel mesh networks with stationary router nodes, such as community wireless networks. A good channel assignment is given as the one which can minimize interference of each link from its neighboring links and subsequently improve the network throughput. In response to it, we introduce an interference...
In multihop wireless networks each node is equipped with multiple radio interfaces, and multiple channels are available for communication. One of the major problems in such networks is the capacity reduction due to the interference among multiple simultaneous transmissions. In order to effectively minimize interference, this paper proposes a QoS routing protocol CATR based on channel assignment and...
