This paper presents a synthetic evaluation method for power quality based on fuzzy cluster analysis (FCA). First of all, with the membership function, the degree of membership of the different indices for different monitoring places was obtained and the fuzzy similar matrix was established. After a series of conversions for fuzzy similar matrix and operations, different clustering of power quality can be obtained. With the dynamic clustering diagram, the power qualities of different monitoring places were sorted and evaluated. Some typical example analysis shows that the FCA is practicable for the synthetic evaluation of power quality, and it is also a new idea. As a matter of fact, the FCA overcomes evaluation standard limitation too definitely on evaluation results, takes into the effect of general elements on power quality and ensures objective and precision. The FCA offers a scientific basis for customers to select power suppliers and price according to power quality.","PeriodicalId":181574,"journal":{"name":"2006 International Conference on Power System Technology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125549104","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}

Simulation studies in the article make use of the EPOCHS (Electric Power and Communication Synchronizing Simulator) platform, which enables the simultaneous study of substation data flows according to both electric power, using PSCAD/EMTDC, and communication network, using NS2, perspectives. EPOCHS allows users to see how faults in the power network, modeled in PSCAD/EMTDC, impact communication traffic levels, within NS2, within and between substations and other power data sources. EPOCHS can be used to strictly simulate the time field characteristics of emergent events such as relay actions and breaker trips. At present, the network-103 protocol is often adopted in conjunction with the 104protocol/TCP communication protocol. This paper creates a 104protocol/UDP scheme, and compares its real-time performance with that of the 104protocol/TCP scheme within a simulated substation using the EPOCHS platform.","PeriodicalId":181574,"journal":{"name":"2006 International Conference on Power System Technology","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126523990","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}

The underlying idea is to train an artificial neural network ANN to learn the behaviour of an external power system. After training, the ANN can be attached to the study system at its boundary buses, replacing the external power system and reproducing its behaviour. The equivalent model proposed in the article expresses the relationship between the power flows in the interconnection lines and the phase and voltage of the boundary buses. Thus, no external system information is required for constructing the equivalent. The model is functional in both directions, i.e using power flows as inputs and phasor voltages as outputs or using phasor voltages as inputs and power flows as outputs. The method was implemented and evaluated on the IEEE-30 bus system and on the Chinese Jiangxi province power system containing 294 buses. The results show that, given appropriate training, the ANN can serve as a model for a power system in an accurate and robust manner. Contrary to the classical methods, the non-linear character of the ANN enables it to accurately model the functioning of the external system also after major operating condition changes such as branch and generator outages.","PeriodicalId":181574,"journal":{"name":"2006 International Conference on Power System Technology","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126274075","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}
