A Novel Protection Strategy for Single Pole-to-Ground Fault in Multi-Terminal DC Distribution Network

Energies, 2023
The single pole-to-ground (SPG) fault is one of critical failures which will have a serious impact on the stable operation of the multi-terminal DC distribution network based on the modular multilevel converter (MMC).

Accurately and Efficiently Interpreting Human-Robot Instructions of Varying Granularities

, 2017
Humans can ground natural language commands to tasks at both abstract and fine-grained levels of specificity. For instance, a human forklift operator can be instructed to perform a high-level action, like "grab a pallet" or a low-level action like "tilt ...

Ground Fault Detection of Small Resistance Grounding System Based on Improved Phase Current Abrupt Variable Method

Journal of Physics: Conference Series, 2023
Abstract When a high fault resistance happens in a small resistance ground system, the protection device is simple to be unsuccessful to manage. By analyzing the characteristics of positive, negative currents in the additional state of fault, it is found that the fault detection method constructed only by the phase current increment ...

Constraints, Lazy Constraints, or Propagators in ASP Solving: An Empirical Analysis

, 2017
Answer Set Programming (ASP) is a well-established declarative paradigm. One of the successes of ASP is the availability of efficient systems. State-of-the-art systems are based on the ground+solve approach.
