With interoperation and interconnectivity of intelligent electronic devices (IEDs) in smart substations increasing, switch networks in smart substations are gradually becoming difficult to manage and maintain. This paper presents a dynamic topology discovery method tailored for smart substation networks based on MAC address matching, which goes beyond topology discovery algorithms for conventional...
When two-phase earthing fault occurs in different sections of a feeder in a distribution system, part of section switches may have two phase fault current flowing through and part of section switches may have one phase fault current flowing through. So, fault current characteristic of this kind of fault is different from that of interphase short circuit fault. Then the traditional matrix algorithm...
This paper presents a distributed scheme to achieve the impact time consensus of multi-missile. The scheme is a combination of ITCG (Impact-Time-Control Guidance) law and multi-agent consensus strategy. Each missile updates its acceleration, which is perpendicular to missile velocity, based on its LOS (Line-of-Sight) rate and the neighbor missiles' maximal impact time estimation. We show that either...
We proposed a design and its implementation of digital multimeter module based on ARM. LTC2440 was employed to conduct high-precision A/D conversion, and S3C2440 was utilized as the master chip to control analog switch group to carry out function setting and range switching, and perform data processing and real-time measurement result displaying as well. It was proved that, the digital multimeter...
In this paper, the dynamically-allocated virtual channels (VCs) architecture with congestion awareness is introduced. All the buffers are shared among VCs whose structure varies with traffic condition. In low rate, this structure extends VC depth for continual transfers to reduce packet latencies. In high rate, it dispenses many VCs and avoids congestion situations to improve the throughput. We modify...
