Three-section current protections will no longer be applicable. Therefore, a new protection scheme which is suitable for the distribution network contained DG be proposed, which is that the protections lying on the downstream lines of DG need to have new setting value, and the protections with the directional components need to be installed on the line between the power and DG. Based on the qualitative analysis of the influence of DG combined into the network on the traditional current protection of distribution network, this paper proposed a new directional current protection on the basis of the positive- sequence fault component. The scheme using fault component principle analyzed the phase angle difference of the positive- sequence current in one period just before the fault and that just after the fault, worked out the protection criterion of the positive and negative fault, and thereby realized the fault location.","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"87 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":"132889740","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}

Bus angles and the angle differences between buses are important for the study of power flow, stability, protective relaying, etc. This paper shows the magnitude of voltage angles for some meaningful buses. Magnitudes of the real and imaginary part of the complex voltage angles of the buses are compared.

Accordance with the State Grid Corporation of the “three sets five” management requirement, a real-time comprehensive data collection monitoring system was built which formatted a integrated distribution network data center in county power supply company, in order to provide technical support for great marketing system. With “SG186” engineering, a integrated enterprise information management system was built, which formatted a non-real-time systems integration data center, in order to achieve the application system data integration for enterprise production and management.

The frequency characteristics of lumped parameters circuits are analyzed and compared with the distributed parameters circuit. From characteristic analysis, the effective frequency band that the lumped parameters circuit can be taken as the equivalent of transmission line was obtained. Considering effective frequency band and model complexity, the selection pinciple for application is proposed. The research results showed that Γ section has the best approximation and Γ section has the simplest model equation.

The scheme, referred to as the Back-up Protection Decision System (RBDS), is implemented by using three relevant matrixes SF, TF and DE, and three action factors α, β and γ. The RBDS provides optimal fault clearance for faults located anywhere on the protected network. To achieve an optimal response, the RBDS needs to know the topology of the network and the operating information of back-up relays. Based on this information, the Back-up Protection Decision System will try to identify the line which contains a fault. The relaying protection N-1 operation statuses are analyzed. The results of case studies show that this scheme based on the union back-up protection information is simple and convenient for fault determination, and the results are exact against N-1 operation statuses that can improve the performance of the back-up protection system.","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"36 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":"123382192","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 dedicated particle encoding with the mesh information of the distribution network can effectively avoid producing a large amount of invalid solutions.
