The relay uses the magnitude of the positive-sequence component in the fault current to detect a fault on a parallel WTG, connected to the same power collection feeder, or a fault on an adjacent feeder; but for these faults, the relay remains stable and inoperative. A fault on the power collection feeder or a fault on the collection bus, both of which require an instantaneous tripping response, are distinguished from an inter-tie fault or a grid fault, which require a delayed tripping, using the magnitude of the positive-sequence component in the fault current. The fault type is first evaluated using the relationships between the positive- and negative-sequence fault components depending on type of fault. Then the magnitude of the positive-sequence component in the fault current is used to decide on either instantaneous or delayed operation. The operating performance of the relay is then verified using various fault scenarios modelled using EMTP-RV. The scenarios involve changes in the position and type of fault, and the faulted phases. Results confirm that the relay can successfully distinguish between faults that require an instantaneous, delayed or non-operation response.","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123409447","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}

A variety of SG functions affect the power system, and as the number of these functions increases, the influence of the SG in a power system increases as well. Therefore, SSAS will become increasingly important for the application of SG in power systems. Most reported work on this subject has been on the implementation of conventional protection and automation schemes in the IEC 61850 environment. However, these studies did not indicate the importance of a SSAS or define a SSAS in the context of a SG; a conceptually ambiguously SSAS formed the basis on which their algorithms and systems were proposed. In order to clarify this ambiguity, this paper proposes both a definition and a concept of SSAS. This paper proposes the concept from two perspectives; the first perspective addresses the change required in a powerful new system environment that considers SG. The second perspective involves the use of smart functions that enhance the operational efficiency of a SSAS. The concept of the system environment takes into consideration the type of communication network, network topology, protocol, cyber security, IEDs and other automation devices, and the influence of Distributed Generation (DG). In addition, the concept of smart functions takes into account optimized operation, protection, restoration, a distributed control operation, and microgrid operation.","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"788 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120876895","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 is hard to regulate the voltage and reactive power of Guizhou power grid by manual operation. In this paper, adopting to the successful experiences in automatic voltage control (AVC) system of several power companies in Europe and China, a new decomposition and coordination method is presented for multivariable coordinated control between generators, shunt capacitors, shunt reactors and adjustable reactive loads. Firstly, the method utilizes the primal-dual interior point algorithm to solve an large-scale discrete and mixing optimal reactive power flow (ROPF) calculation, which gives an optimal voltage profile of the whole power grid; Then the method utilizes the extended coordinated secondary voltage control to optimize the regional reactive power distribution with discrete and mixing variables coordination based on the local balance of reactive power, whilst satisfying the optimal voltage profile. The substation of district power network is equivalent to the adjustable reactive loads with coordination between provincial and district AVC systems. The paper also presents a new method of main and auxiliary dual instructions, which is used to control the plant voltage by master station. The newly developed AVC system has been put into practical operation in Guizhou power grid, and the results show that the AVC system is remarkably effective.","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124835283","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}
