Power system monitoring and source control of the Space Station Freedom DC power system testbed [PDF]

Unlike a terrestrial electric utility which can purchase power from a neighboring utility, the Space Station Freedom (SSF) has strictly limited energy resources; as a result, source control, system monitoring, system protection, and load management are ...

Transient stability emergency control of power systems employing UFLS combined with generator tripping method [PDF]

, 2010
This paper concerns with transient stability control which is part of transient stability assessment which needs to be considered so that the power systems remained intact when failures originating from faults occurred in power systems. Conventional UFLS

An overview of out-of-step protection in power systems [PDF]

, 2017
Power system is subjected to an extensive variety of little or bigger disturbance to the system during the operation. The power system that designed as one of the main requirement is to survive from the larger type of disturbances like faults.

Modeling and Recognition of Smart Grid Faults by a Combined Approach of Dissimilarity Learning and One-Class Classification

, 2014
Detecting faults in electrical power grids is of paramount importance, either from the electricity operator and consumer viewpoints. Modern electric power grids (smart grids) are equipped with smart sensors that allow to gather real-time information ...

Update of an early warning fault detection method using artificial intelligence techniques [PDF]

, 1997
This presentation describes a research investigation to access the feasibility of using an Artificial Intelligence (AI) method to predict and detect faults at an early stage in power systems. An AI based detector has been developed to monitor and predict

Parent Quality of Life at Two Years Following Their Child's Completion of Acute Lymphoblastic Leukemia Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Parents of children treated for acute lymphoblastic leukemia (ALL) often experience significant caregiver burden and disruption to their well‐being. While parent quality of life (QoL) during treatment is well characterized, little is known about outcomes during early survivorship.

Dynamic reactive power reserve assessment method for hybrid AC/DC networks based on a reduced equivalent model of an LCC‐HVDC converter process

IET Renewable Power Generation
LCC‐HVDC technology has been widely applied. Commutation failure is a common disturbance in converter stations. In the absence of an adequate and rapid dynamic reactive power supply, the system is prone to trigger DC blocking.
