Designing a composite deep learning based differential protection scheme of power transformers

Applied Soft Computing, 2020
This paper proposes a novel differential protection scheme based on deep neural networks (DNN). The goal is to propose a fast, reliable, and independent protection scheme in distinguishing inrush current from internal fault in power transformers, as the ...

Path-based Protection in WDM Networks with Differentiated Quality-of-Protection

2006 IEEE International Conference on Communications, 2006
The design of a survivable network with path-protection involves the provisioning of a primary and a backup path for every connection request. To optimize bandwidth usage under path-based protection, backup paths are allowed to share bandwidth under single failure model.

An enhanced sub-cycle statistical algorithm for inrush and fault currents classification in differential protection schemes

International Journal of Electrical Power & Energy Systems, 2020
Differential protection is a widely-used approach for power transformer protection, the performance of which may be, at times, challenged due to the inrush current and current transformer (CT) saturation.

Adaptive differential protection scheme for wind farm integrated power network

Electric power systems research, 2020
In this paper, an adaptive differential protection scheme is proposed for wind farm integrated power network. Any fixed threshold setting based protection scheme is not always suitable for the different operating conditions of power system.

Protection of Transformer by Using Differential Protection Scheme

2023
Differential protection is provided in the electrical power transformer which are higher rated. This type of protection can detect internal faults in the transformer. However, it cannot prevent external faults from occurring in the transformer. If a short circuit is detected in the bushings, then the Buchholz relay cannot effectively cover it.

Discrete Fréchet distance algorithm based criterion of transformer differential protection with the immunity to saturation of current transformer

, 2020
The saturation of current transformers (CTs) has adverse impact on the reliability of the transformer differential protection. However, the overall phase information of currents are less affected by CT saturations.

Differential protection of converter transformers

2016 17th International Scientific Conference on Electric Power Engineering (EPE), 2016
In this paper, development of the special converter transformer model (with 5 windings) and testing results of its differential protection is presented. The special converter transformer is mainly used for supply of rectifiers or converters, FACTS devices etc. This type of transformer can introduce non-standard fixed phase angle shifts such as 20o, 15o,

Swarm intelligence-based differential protection scheme for wind integrated transmission system

Computers & electrical engineering, 2020
Conventional differential protection scheme considers a fixed threshold to detect the fault in a transmission system. In a wind integrated transmission system, any fixed threshold-based protection function is not reliable always due to the dynamic ...
