In this paper, SDH-SLOTOE is expanded to a PTN-SLOTOE platform. The Ethernet Synchronization Messaging Channel (ESMC) defined in ITU-T G.8264 is supported, and multi-standby synchronous links are also supported. This platform has three main functions-testing, optimizing and evaluating. In testing step, the mistakes and potential mistakes are found out according to the rules. In optimizing step, optimizing strategies are selectable, and the mistakes and potential mistakes are corrected to the best of their abilities under selected strategies. In evaluating step, the entire topology is evaluated. The most significant node and link can be found. At last, a demonstration and its optimized result are presented. The result shows that the PTN-SLOTOE platform can optimize the topology perfectly.","PeriodicalId":169553,"journal":{"name":"2010 International Conference on Power System Technology","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125766300","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}

It firstly extracts a weak damping component strongly associated with objective mode from each tie-line active power signal came from WAMS(Wide Area Measurement System), through a low-pass or band-pass filter which is designed by a priori modal knowledge obtained from off-line calculation. Then the self-correlation and cross-correlation coefficients resulted from CA of these time-domain signals are used to determine a inter-area mode shape of tie-line power deviation and equivalent speed deviation which is always able to correspond to a mode. Finally, the results about IAO features are checked with the modal form(MF) from off-line calculation and on-line correction in order to confirm the dominant mode and its mode shape at current state. Two pairs of stationary and non-stationary synthetic signals are utilized to verify the applicability of CA. The case studies have been carried out on a 4-area and 9-bus system and a planning case in East China Power Grid(ECPG), and the results show that the proposed algorithm is efficient and effective, and also indicate the potential practicability for WAMS of bulk power system.","PeriodicalId":169553,"journal":{"name":"2010 International Conference on Power System Technology","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127956711","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}

It proposed a fast algorithm to estimate dynamic load shedding amount based on the transient energy margin sensitivity and the power flow distribution factor. The transient energy margin sensitivities are highly significant in quick determination of stability limits. The power flow distribution factors can be used for fast computation of line flow limits. The method calculated load shedding amount by means of comparing interface on-line flows and interface flow limits in an emergency in real-time monitoring. Tests on power systems had proven that this method yielded dynamic load shedding amounts rapidly and efficiently.

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.
