Research on adaptive protection based on integrated protection

2011 International Conference on Advanced Power System Automation and Protection, 2011
Generally, the three-stage current protection and the instantaneous under voltage protection with current supervision are set to protect the low-voltage distribution system. The protection range of adaptive current instantaneous protection, irrelevant to the fault type of the power system, will be affected by the different operating mode of the system.

Adaptive Protection Systems

2019
Sustainable resources would replace traditional energy production solutions in the near future. There are determinant factors that force to adopt the changes in actual power system: environmental protection, and the increasing price of natural gas, coal and oil. The chapter provides a short overview of protection functions in adaptive systems. Nowadays,

Adaptive Zonal Protection for Ring Microgrids

IEEE Transactions on Smart Grid, 2017
In a fault situation on a microgrid with multiple sources, a ring distribution architecture permits healthy parts of the power distribution network to remain operational while isolating a fault. However, fault localization in a multi-ring power distribution system can be considerably more complex than for a radially distributed network.

Reconfigurable ECC for adaptive protection of memory

2013 IEEE 56th International Midwest Symposium on Circuits and Systems (MWSCAS), 2013
Post-silicon healing techniques that rely on built-in redundancy (e.g. row/column redundancy) remain effective in healing manufacturing defects and process variation induced failures in nanoscale memory. They are, however, not effective in improving robustness under various run-time failures. Increasing run-time failures in memory, specifically in case

Adaptive Protection for Preserving Microgrid Security

IEEE Transactions on Smart Grid, 2019
The low inertia renders renewable-based microgrids ( $\mu$ Gs) more susceptible to incipient faults and makes it more difficult for distributed systems to maintain a reasonable margin for dynamic security. This paper studies the $\mu\text{G}$ security using a three-stage approach to the power system protection.

Adaptive protection scheme for smart grids

12th IET International Conference on Developments in Power System Protection (DPSP 2014), 2014
The amount of distributed generation (DG) connected to distribution networks is increasing. This can cause challenges for traditional protection of distribution networks due to bidirectional power flows, fault current contribution of DG units and grid code fault-ride-through (FRT) requirements.

Adaptive data protection in distributed systems

Proceedings of the third ACM conference on Data and application security and privacy, 2013
Security is an important barrier to wide adoption of distributed systems for sensitive data storage and management. In particular, one unsolved problem is to ensure that customers data protection policies are honored, regardless of where the data is physically stored and how often it is accessed, modified, and duplicated.

An Adaptive Approach in Digital Distance Protection

IEEE Power Engineering Review, 1991
Adaptive distance protection can be obtained by forming an adaptive control system, and rules about information, functions, and time sequence must followed in its design. Three adaptive methods are suggested to deal with the following problems: (1) the effect of frequency variation, (2) the effect of fault resistance in single-phase-to-ground faults ...

Protective Adaptation of Brain to Water Intoxication

Archives of Neurology, 1973
An animal model of inappropriate antidiuretic hormone secretion was used to study changes in water and electrolytes in water intoxication. As the serum became hypotonic, brain and muscle initially reacted by swelling and decreasing sodium content. Subsequently, muscle continued to swell and maintained normal potassium levels.
