In some cases, voltage dip may lead to interruption of major advanced building facilities inside the building like tripping and sudden stoppage of chiller plant and lift. A number of analysis and tests were conducted to verify the ride-through capability for building facilities such as building management system (BMS) and lift in developing a practical and sustainable solution. The ride-through solution for BMS is a successful story that involves cost effective investment for improving the PQ compatibility of the susceptible equipment. Some lifts may also trip during voltage dip. Although most modern lifts are equipped with auto-restart, there were still cases where the feature was unable to function and resulted in shut-in-lift situation. Unless the lift was locked off by the operation of the safety gear in which attention by lift maintenance personnel was necessary, in most other cases the situation could be improved with suitable mitigation measures. These include remote alarm, post-voltage-dip-operation [1] and regenerative braking features. This paper describes the major initiatives formulated to meet this PQ challenge for advanced building facilities such as BMS and lift. The mitigation measures for BMS and lift combating voltage dip incident will also be presented.","PeriodicalId":330524,"journal":{"name":"2013 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131498993","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}

This may bring high vulnerability to the cyber-physical power system, which is becoming more dependent on the communication technologies deployed in the SCADA system. The reliability of the power system may be compromised by the worms spreading through the SCADA networks. In this paper, the impact of worm spreading attacks on power system reliability is analyzed. A forced outage rate (FOR) model is proposed considering the impacts of spreading worms on the reliability characteristics. The spreading and detection models of active worms through the network in the SCADA system lead to non-negligible effects on the FOR values. With different FOR values derived by the models of both worm spreading and detection, the loss of load probabilities (LOLP) in two reliability test systems are estimated. The simulation results demonstrated that the reliability of the power system is simultaneously influenced by both the spreading and detection intervals of active worms.","PeriodicalId":330524,"journal":{"name":"2013 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124131479","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, unipolar SPWM full-bridge inverter causes time varying common-mode voltage. The variable common-mode voltage excites leakage current through the parasitic capacitance between the PV array and the ground, which restricts its application in transformerless grid-connected photovoltaic (PV) inverter. In order to solve this problem, an optimized full-bridge topology is proposed in this paper. The topology uses an additional branch to be clamped the potential of the freewheeling path to the half of the input voltage in the freewheeling period, which guarantees no variable common-mode voltage in the unipolar SPWM full-bridge inverter. The proposed topology poses advantages such as higher efficiency, simple switching, and topological simplicity as compared to existing topologies. The proposed topology has been verified in MATLAB/Simulink environment with satisfactory results.","PeriodicalId":330524,"journal":{"name":"2013 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127113565","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}
