The proposed multi-agent system consists of several facilitator-agents (FAGS), equipment-agents (EAGs) and switch-box-agents (SBAGs). FAG acts as a manager for negotiation process between agents. EAG corresponds to an equipment of the electric power system such as a bus, a transformer and a transmission line, while SBAG is a pseudo-object which consists of neighboring circuit breakers and disconnecting switches. The proposed multi-agent system realizes appropriate switching operations by interacting with neighboring agents. Computer tests on a model system show that the proposed approach is effective and promising.","PeriodicalId":289535,"journal":{"name":"IEEE/PES Transmission and Distribution Conference and Exhibition","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131871250","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}

China is a country with vast power supply area and population, deviation between locations of generations and loads, mountainous landforms, and limited quantity of right of way. More HVDC transmission projects with long distance, high voltage and large capacity will be constructed to meet the requirement of power transmission from the hydropower stations developed in the western area to the load centers in the east. The distance between two power grids is too long to adopt AC for interconnection. Back to back HVDC links will be used for interconnection.

These transactions must be monitored and restricted to a limit decided by the transmission network capability. However, due to large size of the present day power systems, it becomes very difficult to monitor feasibility of all the transactions, especially when performed online. A sensitivity based static network reduction technique has been proposed which reduces the system size, thereby allowing fast and easy power transaction assessment. The extent to which a network is to be reduced can be controlled. The proposed technique has been tested on a practical Indian system network.","PeriodicalId":289535,"journal":{"name":"IEEE/PES Transmission and Distribution Conference and Exhibition","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134157211","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}

Such an occurrence leads to freer customer choice and open market competition. This change will inevitably transform the meter reading market. No longer will manual reading of the energy consumption be adequate. A full-scale effort to automate the kilowatt-hour (kWh) meter reading will become a necessity. Of all available media used in the transmission of the meter reading, only power line communication medium is cost-effective to the energy suppliers since the infrastructure of the low-voltage (LV) power network can also be used as a telecommunication network. Remote meter reading through power line medium has rarely been implemented in high-rise, densely populated buildings. The large quantity of kWh meters in high-rise buildings, particularly of residential type, offers a potential business opportunity. Automating the kWh meter reading through the LV power line communication medium forms the basis of this work. However, the power line is a hostile communication medium and it is essential to know its characteristics. This paper describes a prototype automated meter reading system, using the power lines communication medium and frequency shift keying modulation, operating in the EN 50065-1 A Band. Its performance and reliability aspects are also presented.","PeriodicalId":289535,"journal":{"name":"IEEE/PES Transmission and Distribution Conference and Exhibition","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134334253","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 particularly concerns with developing a software-based tool for the simulation of logic blocks as applied to substation control systems. Several existing techniques used for testing substation control systems are described. A brief discussion illustrating the main requirements for the development of a simulator is given. This is followed by giving a summary of the most widely used simulation techniques, highlighting the reason behind the choice of the interpreted technique in this work. An extra attribute, i.e., status check, added on top of the traditional Boolean simulation is then given. Two different type of interfacing methods are then described in order to examine and determine which of them is most suitable for the simulation of substation control systems. These interfaces are based on command-driven and menu-driven approaches.","PeriodicalId":289535,"journal":{"name":"IEEE/PES Transmission and Distribution Conference and Exhibition","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115562993","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}

Due to increasing demands for the high reliability, the fast service restoration has been a hot issue with the fault tolerable distribution system. In order to ensure high reliability, the scope of service restoration should be extended to severer faults such as multi-feeder outages, bus outages and transformer outages at the substation, and out-of-services of a whole substation. In this panel session, the fast service restoration is discussed with the necessity of developing new approaches to be adapted to the distribution system under deregulation, mainly focusing on fast solution search algorithms, multi-switching strategies for severer fault occurrence, search for the fault section, and fast power flow calculation.","PeriodicalId":289535,"journal":{"name":"IEEE/PES Transmission and Distribution Conference and Exhibition","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115651081","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}

We investigated magnetic field distribution around 3-phase GIS (gas insulated switchgear) by comparing the measurement results with calculation using finite element method (FEM). By simultaneous measurement of conductor current, we could have very good agreement of calculation results with measurement one. Particularly, the drastic mitigation of magnetic field with distance from GIS was characterized and quantified by comparing the one in open-air substation. In addition, the magnetic field distribution in GIS was discussed by analyzing the influence of induced current distribution in GIS sheath.
