Energy distribution companies have to reconnect areas affected by an outage within a very short time, and observe operational constraints, to avoid the possibility of severe financial penalties by regulatory bodies. Distribution networks are often operated with a radial topology, but, ideally, should have more than one route to deliver energy to any node of the network. Switches in the network are opened to create the radial topology used in normal operation, and, in the case of an outage, alternate routes are activated by opening or closing switches located at specific points of the network. Given an outage situation (in our case represented by te disconnection of a single branch), the choice of which switches should change their state is a combinatorial optimisation problem, with a search space of 2k, where k is the number of switches. Because of the exponential complexity, exact methods are prohibitively time-consuming. This work presents a genetic algorithm that provides a rapid answer to network managers in terms of a switching strategy to reconnect the affected area. The method takes into account the radial topology of the power flow and the operational limits of voltage and cable load. Computational tests were conducted on a real network with 96 buses and 16 switches, located within the operational area of Energy Australia. This paper describes the genetic algorithm in detail, presents thorough computational tests, and a complete contingency plan for the test network.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133009425","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 solution utilizes commercial digital relays for a local bay control using copper wiring, as well as the IEC 61850 in a communication network. From the result tests, one can observe the reliability of the implemented logic using IEC 61850. From the developed application, it can be seen that the use of the process bus is very beneficial because it replaces the functional circuit, implying in a considerable reduction of the electrical connections involved. Another aspect shown in the paper is a critical view concerning the comparison of using copper wiring and IEC 61850 for the bay control.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133357955","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 the state space, the control strategy is the states feedback and the most used techniques are the LQR and the LQG. In despite of the good results obtained from these methods, the control design is not a straightforward task due to the trial and error method involved in the definition of weight matrices. In such cases, may be hard tuning the controller parameters in order to obtain the optimal behavior of the system. In this work, it proposes a states feedback technique in which there are no trial and error processes involved and the control design is carried out to fulfill specifications, for maximum overshoot and accommodation time. The proposed technique is based on the modification of the states transition matrix and uses genetic algorithms. The obtained results show that is possible to design controllers which fulfill design specifications.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133175424","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 order to study the impact of a wind farm on the dynamics of the power system, a major issue is to develop adequate equivalent models that allow characterizing the dynamics of all individual WTGs. In this sense, with the advance of power electronics, direct-driven permanent magnet synchronous generators (PMSGs) have drawn increased interest to wind turbine manufacturers due to its advantages over other variable-speed WTGs. This paper presents a comprehensive dynamic equivalent model of a wind farm with direct-driven PMSG wind turbines and its control scheme. The proposed simplified modeling is developed using the state-space averaging technique and is implemented in the MATLAB/Simulink environment. The dynamic performance of the wind farm and its impact on the power system operation is fully evaluated using the phasor simulation method.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122863498","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 information is obtained from real measurements taken from power quality monitors in distribution substations. The proposed methodology makes use of a fault location algorithm (FLA) in radial networks, which deals with the waveforms acquired whenever a behavior alteration is detected. In this case an event is generated to obtain: i) the voltage and currents waveform prior and during the fault, ii) the type of fault and iii) the fault duration. The FLA uses voltage and current values to obtain the possible fault location and impedance. Different events in a real distribution network are evaluated during the monitoring period, which allows for the evaluation of probability functions for each studied variable, thus showing the adequate statistic parameters for short circuit and power quality studies.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"362 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124552477","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}

As part of the project it was developed a system for the analytical interpretation of the protection in order to generate tripping diagnosis of protection relays in power distribution substations. The system was designed to be suitable to different relays technologies (from electromechanical to digital), to different manufacturers and also to different communication protocols. The system get local information from the substation and data from protection relays, using a rule-based expert system (CLIPS). The purpose of the system is to analyze and interpret protection equipment tripping in a distribution substation. The system may be an important tool to assist in analyzing tripping protection events. It can provide diagnosis for proper parameterization of protection relays tripping curves. The system also recognize which function of the protection relay was activated as well as other characteristics such as the operating time, fault type with its currents, voltages and phases involved. The system may also analyze if the circuit breaker responded properly to trip commands. The laboratory results presented were obtained from different protection relays of different types, different manufacturers and different communication protocols. In addition, to simulate faults, it was used a relay testing equipment. The protection relays were arranged to simulate a feeder bay of a distribution substation, thus allowing the configuration of different power system faults for different types of relays.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116886817","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}
