SOHO operations and ground system

Space Science Reviews, 1994
SORO is a joint ESA/NASA mission to study the sun from its interior to, and including, the solar wind in interplanetary space. It is currently scheduled for launch in 1995. After launch SORO will be operated from the Experiment Operations Facility (EOF) at Goddard Space Flight Center (GSFC). The EOF will consist of facilities for instrument commanding,

Globality levels of grounding systems

2014 IEEE/IAS 50th Industrial & Commercial Power Systems Technical Conference, 2014
IEC Standard 61936-1 “Power installations exceeding 1 kV a.c.” defines the “Global Grounding System” (GGS). It consists essentially in the interconnection of the MV/LV grounding systems, generally at least by means of the MV cables metal sheaths and/or of dedicated ground conductors buried along the MV cable lines.

Needs of Management of the Grounding Systems

IEEE Transactions on Industry Applications, 2015
This paper suggests an advanced approach in the verification of the adequacy of a grounding system (GS) located in a common zone of influence with other GSs, taking into account the mutual interferences between the GSs. In fact, the presence of other GSs can transfer inadmissible touch and step voltages on the testing GS, particularly sensitive for ...

TN-Grounding Systems for the Emerging Cold Ironing: Multiple Grounded System vs Island System

2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2018
The commercial routes interconnection in maritime world transport requires common criteria for the standardization of shore connection's rules in port areas. A brief focus on the part 1: High Voltage Shore Connection (HVSC) Systems (IEC-ISO-IEEE 80005–1) has been presented that is an example of global harmonization.

Ground Segment of Distributed Ground Station System

EUROCON 2007 - The International Conference on "Computer as a Tool", 2007
The article discusses an innovative method of data transmission between a satellite and the Earth. The authors suggest using a distributed network of ground stations, which simultaneously receive data from the satellite. The article presents new solutions, which allow improving the quality of receiving channel in comparison to an antenna array ...

On the Concept of Grounding Impedance of Multipoint Grounding Systems

IEEE Transactions on Electromagnetic Compatibility, 2014
An N-port equivalent circuit approach is adopted to model a multipoint grounding system, N being the number of injection points. A methodology is proposed to determine the parameters of the N-port equivalent circuit from either numerical simulations or experimental measurements.

Hybrid grounding of electrical systems

2016 Petroleum and Chemical Industry Technical Conference (PCIC), 2016
This paper will discuss the many different ways to ground medium voltage generators. Single source as well as multiple source units, either unit connected or bus connected, will be shown with preferred grounding schemes.

Grounding System Parameters and Expression of Ground Resistance

2016
In any electrical circuit network, the circuitry that provides a path between the parts of the circuit and the ground, is known as the grounding system. The grounding system is required for reliable operation of any electrical equipment including generator, transformer, power system tower, and other power system installation under fault conditions.

Ground-3D: A FEM CAD/CAE System for Ground Systems Analysis

Digest of the Fifth Biennial IEEE Conference on Electromagnetic Field Computation, 2005
A complete modelling of a grounding system made by ground meshes, connected or not in multilayer soil is presented. A 3D approach is used to model rods or wire conductors, grave layers and conductor plates that are commonly found in grounding systems.

Grounding systems research: re-establishing grounded theory

Proceedings of the 35th Annual Hawaii International Conference on System Sciences, 2003
In the field of information systems (IS) there has been a growing trend away from a technical view of systems (with the system literally seen primarily in terms of the physical devices), to one that seeks to account for nontangible aspects such as cognition, culture, motivation and so on.
