Resumo: | In this dissertation, we present a detailed study of techniques for islanding detection of distribution systems in the presence of distributed generators in various forms of access and connection. The aim is to set up protection system solutions capable of ensuring the detection of the islanding based on local passive techniques, which have lower costs with respect to remote techniques, for example, the transfer trip. The objective of this work is to achieve through the association of several islanding detection techniques in order to achieve adequate reliability of distributed synchronous generators protection system. Among the existing techniques, the protection functions studied were the overfrequency and underfrequency (ANSI 81 o/u), rate of change of frequency (ROCOF or ANSI 81 df/dt), vector jump (ANSI 78) and directional reactive power (ANSI 32Q). It was found that the 32Q function for loads with inductive power factor less than one complements the functions based on frequency precisely in the range where these are insensitive to islanding, wherein the threshold for operation of this relay depends on the equivalent load power consumed locally. For cases of islanding caused the intentional opening of the distribution feeder, the islanding detection for loads with a inductive power factor can be guaranteed with the use of passive local techniques without the need to burden the installation of synchronous generators protection systems distributed. Although in practice it is very unlikely a distribution circuit has a unity power factor, the association of these protective functions arises as a good solution for the detection of islanding of distributed synchronous generators. |

Visa definir soluções de composição de sistemas de proteção capazes de garantir a detecção do ilhamento baseados em técnicas locais passivas, que apresentam custos mais reduzidos com relação às técnicas remotas, como por exemplo, a teleproteção. O objetivo deste trabalho é alcançar, por meio de associação de várias técnicas de detecção de ilhamento, um grau de confiabilidade adequado do sistema de proteção de geradores síncronos distribuídos. Dentre as técnicas existentes, foram estudadas as funções de proteção de sub e sobrefrequência (ANSI 81 o/u), taxa de variação de frequência (ROCOF ou ANSI 81 df/dt), salto de vetor (ANSI 78) e direcional de potência reativa (ANSI 32Q). Constatouse que a função 32Q, para cargas com fator de potência indutivo e menor que um, complementa as funções baseadas em frequência justamente na faixa onde estas são insensíveis a ilhamentos, sendo que o limite para a operação deste relé depende da potência equivalente da carga consumida localmente. Para os casos de ilhamento provocado pela abertura intencional do alimentador de distribuição, a detecção de ilhamento para cargas com fator de potência indutivo poderá ser garantida com a utilização das técnicas locais passivas sem a necessidade de se onerar a instalação dos sistemas de proteção de geradores síncronos distribuídos. Apesar de que na prática é muito improvável um circuito de distribuição possuir um fator de potência unitário, a associação das referidas funções de proteção surge como uma boa solução para a detecção de ilhamentos de geradores síncronos distribuídos.Submitted by JÚLIO HEBER SILVA (julioheber@yahoo.com.br) on 2017-03-24T19:57:30Z No. of bitstreams: 2 Dissertação - Igor Lopes Mota - 2015.pdf: 2620143 bytes, checksum: c895dad8e571f14172d9b7e9506f3d94 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2017-03-28T11:35:07Z (GMT) No. of bitstreams: 2 Dissertação - Igor Lopes Mota - 2015.pdf: 2620143 bytes, checksum: c895dad8e571f14172d9b7e9506f3d94 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2017-03-28T11:35:07Z (GMT).

In this dissertation, we present a detailed study of techniques for islanding detection of distribution systems in the presence of distributed generators in various forms of access and connection. The aim is to set up protection system solutions capable of ensuring the detection of the islanding based on local passive techniques, which have lower costs with respect to remote techniques, for example, the transfer trip. The objective of this work is to achieve through the association of several islanding detection techniques in order to achieve adequate reliability of distributed synchronous generators protection system. Among the existing techniques, the protection functions studied were the overfrequency and underfrequency (ANSI 81 o/u), rate of change of frequency (ROCOF or ANSI 81 df/dt), vector jump (ANSI 78) and directional reactive power (ANSI 32Q). It was found that the 32Q function for loads with inductive power factor less than one complements the functions based on frequency precisely in the range where these are insensitive to islanding, wherein the threshold for operation of this relay depends on the equivalent load power consumed locally. For cases of islanding caused the intentional opening of the distribution feeder, the islanding detection for loads with a inductive power factor can be guaranteed with the use of passive local techniques without the need to burden the installation of synchronous generators protection systems distributed. Although in practice it is very unlikely a distribution circuit has a unity power factor, the association of these protective functions arises as a good solution for the detection of islanding of distributed synchronous generators. |
