International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing (IMIS)

作者： Qin Xin Xiaolan Yao Wei He State Key Laboratory of Power Transmission Equipment & System Security and New Technology College of Electrical Engineering Chongqing University China Department of Applied Mathematics Universite Catholique de Louvain Louvain-la-Neuve Belgium School of Computer Science National University of Defense Technology Changsha China

In a Wireless Sensor Networks (WSN), there are normally one or several sensor nodes working as Access Points (AP), which are able to provide a relay for other sensors to an external Internet connection. Since WSNs are resource constrained, the selection of APs is very crucial in economizing power usage. In this paper, we study the optimal selection of APs to maximize the WSN lifetime. This issue is closely related to routing protocols in WSN. We propose a new adaptive multi-path routing protocol to reduce the energy consumption and guarantee QoS requirements with respect to transmission delay. In this paper, we formulate the issues we mentioned above as a non-linear NP-hard optimization problem. Due to the high computation complexity of this problem, we proposed two polynomial-time approximation algorithms to optimally select APs in the WSN that based on the framework in. Combining with our new adaptive multi-path routing protocol, our preliminary simulation results show that our schemes can save more than 20% energy compared with the existing APs selection schemes with single path routing protocols.

The effort of "Smart Grid" is to modernize grid infrastructure and build-in intelligence to power grids and delivery systems, and their interfaces to customer premises. However, the perspectives range from an emphasis on infrastructure to an emphasis on new paradigm-shifting applications. Alternatively, the smart grid can be thought of as the advanced information technologies that enable the desired analytical applications. As a general understanding, we believe that Smart Grid needs to integrate power system analysis, computing and economics to enhance grid reliability, efficiency, and security, and contributes to the climate change strategic goal. In this Supersession, the analytics that empowers smart grid applications is discussed;and the practical implementation and integration challenges will be presented.

This paper adjusts decentralized OPF optimization to the AC power flow problem in power systems with interconnected areas operated by diferent transmission system operators (TSO). The proposed methodology allows finding the operation point of a particular area without explicit knowledge of network data of the other interconnected areas, being only necessary to exchange border information related to the tie-lines between areas. The methodology is based on the decomposition of the first-order optimality conditions of the AC power flow, which is formulated as a nonlinear programming problem. To allow better visualization of the concept of independent operation of each TSO, an artificial neural network have been used for computing border information of the interconnected TSOs. A multi-area power Flow tool can be seen as a basic building block able to address a large number of problems under a multi-TSO competitive market philosophy. The IEEE RTS-96 power system is used in order to show the operation and effectiveness of the decentralized AC power Flow. ©2010 IEEE.

This paper presented a novel approach to recognize ultra-high-frequency (UHF) signals of partial discharges (PDs). Four artificial insulation defect models were designed to generate PD UHF signals, which were detected by a Peano fractal antenna in experiments. Wavelet packet (WP) decomposition was used to decompose PD UHF signals into multiple scales. A group of energy parameters and fractal dimensions of PD UHF signals were computed and used as the input parameters of a support vector machine (SVM), which was used as the PD pattern classifier. For verifying the results of this approach, a back-propagation neural network (BPNN) was also used for pattern recognition of PD UHF signals. The recognition results showed that the SVM and the proposed parameters were qualified for PD pattern recognition and the SVM had advantages over the BPNN for the purpose. ©2010 IEEE.

This paper presented a novel polydimethylsiloxane/nano-silica (PDMS/nano-silica) hybrid super-hydrophobic coating for anti-icing on insulators. Average water contact angle on the super-hydrophobic PDMS/nano-silica hybrid coating reached 161°. The super-hydrophobic PDMS/nano-silica hybrid coating had a rough surface with micro/nanometer dual-size structure. Icing experiment was carried out to investigate the anti-icing properties of the super-hydrophobic coating on insulator strings. AC icing flashover voltages of the two types of insulator strings were investigated. Results showed that the super-hydrophobic PDMS/nano-silica hybrid super-hydrophobic coating excellently restrained the icing on insulator strings. The AC flashover voltage of the ice coated insulator string with the super-hydrophobic PDMS/nano-silica hybrid coating was 100 kV which was higher than that of the ice coated insulator string with RTV silicone rubber coating. ©2010 IEEE.

Oil-impregnated paper is a major type of insulation in oil-filled power transformers. In converter transformers, windings connected with converter valves have to withstand AC and DC combined voltages. This paper presented the experimental research on electrical breakdown properties of oilpaper insulation under AC-DC combined voltages. electrical breakdown strength of oil-paper insulation specimens was measured through short-time tests under AC, DC, and AC-DC combined voltages. The combined voltages consisted of two different ratios of the AC to DC voltages. Through the constant-stress tests, the times-to-breakdown of oil-paper specimens were measured. Weibull parameters of the times-to-breakdown of specimens were estimated and the inverse power and exponential failure models of the specimens were presented. © 2010 IEEE.

Multicore simulation of an AC-radial Shipboard power system

Multicore simulation of an AC-radial Shipboard Power System

IEEE General Meeting power& Energy Society

作者： F. M. Uriarte K. L. Butler-Purry Power System Automation Lab of the Electrical and Computer Engineering Department Texas A and M University College Station TX USA

This work presents an approach to parallelize the simulation of AC-Radial Shipboard power systems (SPSs) on multicore computers. Time domain simulations of SPSs are notoriously slow due to the order of SPSs and the presence of time-varying component models. A common approach to reduce simulation run-time is to partition power systems using Bergeron's travelling-wave model and to simulate the subsystems on a distributed computer. In this work a SPS is partitioned along cable capacitor loops using a diakoptics-based approach and the simulation conducted on a quad-core computer. A case study is presented that empirically determines a good number of SPS partitions for a multithreaded simulation, such that the speed gain is maximal and accuracy is preserved.

This paper proposes a systematic gain setting method for the positive feedback anti-islanding scheme which is designed to protect the interconnected inverter-based distributed generators (DGs) from islanding operation. Two main factors affecting the performance of the anti-islanding scheme are investigated when the positive feedback gain is tuned. One is the stability impact of the anti-islanding control on distributed generation (DG) systems and the other is the islanding detection time of the anti-islanding scheme. The small-signal model and the electromagnetic transient simulation model of an inverter-based DG system are developed to facilitate the realization of the proposed gain setting method. This method provides a practical and reliable tool for DG planning engineers. ©2010 IEEE.
