The measured soil resistivity data are then used into the CYME GRD software to calculate the soil resistivity and is found to be 63.8 ohm-m. Rectangular grid with the dimension of 50 m by 32 m is considered for the simulation of ground resistance, ground potential rise, touch and step potentials based on the IEEE 80-2000 standard. The simulation result of ground resistance, ground potential rise, tolerable touch and step potentials are found to be 0.66 ohm, 11061.2 V, 1171.3 V, 4193.10 V respectively.

In this paper, we investigated the multiclass classification of mental task using EEG signal. Higuchi Fractal Dimension and 10-Statistic Parameters were used as feature extraction method. The 10-statistic parameters are central tendency type that is, maximum value, minimum value, mean, standard deviation, median, mode, variance, first-quartile, third-quartile, interchange quartile. Multiclass Support Vector Machine with One-against-All strategy is applied to classify EEG signal related to the mental task. The result shows that the Multiclass SVM classifier with 1-against-All strategy using 10-Statistic Parameters has a higher accuracy when compared to Higuchi Fractal Dimension-SVM, Extreme Learning Machine, Back Propagation Neural Network, both of Support Vector Machine 1-versus-1 strategy and 1-versus-All strategy.

The impulse characteristics of grounding grids are studied through simulating corrosion, breakage and sealing-off. Meanwhile, the impact of different impulse points and lightning impulse are also analyzed. The result shows that, with the same current injection point, the impulse grounding resistance rises with the front time of lightning impulse declines. With the same lightning current, when the lightning impulse is injected through the corner of grounding grids, the impulse grounding resistance is bigger than that when the lightning impulse is injected through the center of grounding grids. If the grounding grids has fault, the impulse grounding resistance will increase, but the growing rate has close relation with fault type and lightning current. The study may provide a basis for grounding grids design and evaluation.","PeriodicalId":22200,"journal":{"name":"TENCON 2015 - 2015 IEEE Region 10 Conference","volume":"42 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77071115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is facing a power crisis where there is a continuous increases in an already huge demand in electricity given the limited and scare supply from different power sectors. Consumers are called to be aware of their power consumption and make necessary efforts towards the smart and efficient use of it. As a response, the proponents developed an appliance-level system that monitors and analyzes power consumption. The monitoring subsystem was implemented through a portable hardware black box which includes the power meter sensor, an Arduino microcontroller clone board and a ZigBee shield for wireless transmission to a microcomputer. The Raspberry Pi microcomputer served as a temporary local server for the sync node and the gateway for the data to be stored in an online database. From this, the analysis subsystem retrieves the consolidated data to undergo both retrospective and Winter's forecasting technique. All necessary information, figures and graphs will be presented to the user for interpretation through a simple web application. Overall, the study fulfills its vision of giving people the power over their utility bills by being a tool for raising awareness towards responsibly reducing power consumption to a more efficient use.","PeriodicalId":22200,"journal":{"name":"TENCON 2015 - 2015 IEEE Region 10 Conference","volume":"1 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82401965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Battery modules usually are utilized to generate HV and large currents to drive motors of electric vehicle (EV). The battery modules are controlled and monitored by a system to protect the modules from possible hazards, e.g., battery management systems (BMS). However, since the BMS needs to deal with HV signals, it is very difficult to be implemented using logic integrated circuits (ICs). The proposed design, by contrast, is implemented using a typical 0.25 μm 1P3M 60V BCD process and field programmable gate array (FPGA) to resolve this issue.

When faults of receiving network occur, HVDC recovery characteristics are analyzed, which have an important effect on voltage stability of receiving network. The model of active power and reactive power time series responding to the recovery characteristics is built for simplicity, which is applied to replace HVDC systems for transient simulation. Based on simulating results, at each of time frames, Q-V sensitivity and modal analysis can be utilized, and the moment when the reactive power consumed by the HVDC systems rising to high values is the main concern to investigate voltage stability. Bus participation factors are calculated by modal analysis and weak voltage area is found out.
