The utilization of a CHMI allows the system to reach high voltage without the use of transformers while fulfilling the pulse requirements for effective liquid food sterilization. By using the CHMI topology, no extra clamping diodes or voltage balancing capacitor is needed. In this work, the proposed CHMI circuit operation is simulated using MATLAB/Simulink where unipolar and bipolar square wave pulses with pulse width range of 1 µs to 1 ms are generated. A peak output voltage of 6 kV and peak output power of 3.6 kW have been obtained with both values meeting the pulse specifications for liquid food sterilization applications.","PeriodicalId":379868,"journal":{"name":"2010 4th International Power Engineering and Optimization Conference (PEOCO)","volume":" 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114051147","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}

DG installation in the distribution system is very useful in reducing the line losses, as well as improving the voltage profiles. The proposed method combines particle swarm optimization and the Newton-Raphson load flow method to determine the location and size of the DG. The objective function to be minimized in this problem is the total power losses of the system. The proposed approach has been tested on IEEE 69-bus distribution test system and the program was simulated using MATLAB software. Test results show the effectiveness of the developed algorithm.","PeriodicalId":379868,"journal":{"name":"2010 4th International Power Engineering and Optimization Conference (PEOCO)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130186947","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}

After reviewing the Petri nets theory, then, models of fault diagnosis based on PN are built, and their corresponding logical testifications are carried out. Finally, the validity and feasibility of this method is illustrated by simulation results. It is shown from several cases that the faulted system elements can be diagnosed correctly by use of these models. By proposed method, it is possible to reduce diagnosis time and increase correctness of results compared to traditional methods. It is also suitable to online applications.

Combined transmission line with cable line has considerable effects on power system reliability indices, because high voltage insulations are weak points in power systems in view of reliability that they are used in design of high voltage cables. On the other hand, in each power system with combined lines, optimum design of insulation system and considering suitable protection for cable lines by surge arrester against over voltage, increase power system reliability. Therefore in this study, reliability analysis of power system with combined line is done using event tree method. Also effect of location and number of surge arresters on the combined line reliability indices is studied and then variations the reliability indices have been analyzed by changing in length and age of cable line in the network. Results show that effect of length and age of cable and number of surge arresters in combined line on power system reliability indices is significant.","PeriodicalId":379868,"journal":{"name":"2010 4th International Power Engineering and Optimization Conference (PEOCO)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117130428","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}

In principle, the optimum level of security that a system provides is determined by the interaction between cost of providing extra security and value to consumers. Risks in energy system have to be quantified in order to identify the level of security. To make comparison between cost of providing energy security and level of security, the quantified risks have to be in similar common variable as the costs. Then, an optimum level of security and cost can be estimated using appropriate methods. The objective of this paper is to present the development of Non-delivery Probability Table (NdPT) for use in coal procurements in energy system. This table will provide the probabilities of non-delivery for every supplier involved in supplying fuel for the system. These probabilities then can be used to quantify the risks in energy systems.","PeriodicalId":379868,"journal":{"name":"2010 4th International Power Engineering and Optimization Conference (PEOCO)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122017400","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}
