Its optimum performance is related to the quality of electrical supply. In this sense, when there are variations in the quality of electricity supply, the induction motor can operate in conditions that can affect its performance and shorten its life. In this paper we propose a monitoring of the voltage condition of the supply voltage in induction motors, through a classification using Support Vector Machines (SVM) to detect and classify these events. The necessary data for defining the events associated with the supply voltage are obtained with the use of ATP software, simulating these different conditions in a low voltage motor and the event classification is carried out with the use of SVM. With the use of this mathematical tool, defined areas of disturbs in the voltage will be established from measurements obtained in the simulation of each of the events, which are considered as perturbations in voltage, such as: overvoltage, undervoltage, voltage unbalance, distortion of the voltage wave, voltage sags and simultaneous combinations of some of these events. Assigning tags to each type of disturbance or disturbance combinations allows us to detect and classify the condition of energy supply in induction motors through the SVM. The results show perfect accuracy in the classification of events in the condition of voltage supply of the induction motor, which represents an alternative to the monitoring of these machines in the industry.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"6 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79694263","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}

First, methodology and results of a voltage stability analysis is presented to determine the required rating of the SVC to assure acceptable system dynamic performance. Both SVC and Static Synchronous Compensator (STATCOM) Flexible AC Transmission System (FACTS) technologies were considered and evaluated for this application.

The North American Electric Reliability Corporation (NERC) has adopted standards for generator model validation requiring periodic validation of generator, exciter, governor, and stabilizer models. Using synchrophasor data provides a unique opportunity for generator owners to verify their dynamic models while the units are on-line, avoiding time-consuming and costly off-line tests. This paper describes the tool that uses PMU data at the generator terminals to validate the models without taking them offline and also presents test results. This work is built on the research done by University of Texas Arlington. A two-step process of validation and calibration is used to identify whether the model is valid and then calibrate the model parameters if needed. The validation process has been tested with simulated data and field data.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"1 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88690216","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 proposed market structure enables the integration of microgrids, which provide energy and ancillary services in distribution networks. In the proposed hierarchical structure, microgrids participate in the energy market at the distribution networks settled by the distribution network operator (DNO), and load aggregators (LAs) interact with microgrids and generation companies (GENCOs) to import/export energy to/from the distribution network electricity markets from/to the wholesale electricity market. The proposed approach addressed the synergy of energy markets by introducing dynamic game with complete information for GENCOs, microgrids, and LAs. The proposed hierarchical competition is composed of bi-level optimization problems in which the respective upper-level problems maximize the individual market participants' payoff, and the lower-level problems represent the market settlement accomplished by the DNO or the independent system operator. The bi-level problems are solved by developing sensitivity functions for market participants' payoff with respect to their bidding strategies. A case study is employed to illustrate the effectiveness of the proposed approach.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"31 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87268471","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 principle of duality between the electric and magnetic equivalent circuits is concisely explained. The magnetic equivalent circuit of a two-winding, shell-type, single-phase transformer is extended to the magnetic circuit of a transformer with an inter-turn fault. The model is implemented in the electromagnetic transients program using built-in component models. The model is verified against results published for a 150kVA three-phase transformer and experimental testing on 55kVA three-phase transformer constructed for internal fault testing. While the developed model is for single-phase transformers, extending it to a topology-based model for three-phase, three-legged and five-legged transformers is straight forward. This model may find usage in transformer relay protection studies.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"45 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90749524","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}

Meanwhile work on implementation of best practice on compact SF6 Instrument transformer design to lower its impact to environment and reduce SF6 footprint. The latest Fiber-optical Current Sensor (FOCS) integrated with Disconnect Circuit Breaker (DCB) provide not only a substation footprint reduction over 50% but also an environmental friendly design and improved operation safety for its explosion proof.
