Study on Sharing Earth Electrode of UHVDC

2006 International Conference on Power System Technology, 2006
This paper analyzes the different operation modes of the UHVDC system sharing earth electrode from the aspect of power system stable operation. Two UHVDC system rectifiers and inverters sharing earth electrode were studied respectively by electromagnetic transient analysis software EMTP-RV based on the main parameters of Xiang jiaba to Nan hui ...

Study on Xiluodu and Xiangjiaba UHVDC Earth Electrodes

2006 International Conference on Power System Technology, 2006
Grounding characteristics of linear, star-type and toroidal electrodes are discussed in this paper. Based on the analysis of the performance of double-ring in uniform and horizontal two-layer soils, an electrode model of standard triple concentric rings buried with different depth is presented for plusmn800 kV Xiluodu and Xiangjiaba converter stations ...

Earth-electrode systems for large electric stations

Proceedings of the IEE Part A: Power Engineering, 1957
Interconnected systems have increased considerably in recent years, and the large possible earth-fault currents resulting require further thought being given to earth system design, especially in areas of high soil resistivity. The paper discusses the special practical problems of the design, construction and testing of earth electrode systems for ...

Grounding resistance of a single earthing electrode

Modern Problems of Telecommunications - 2024. Proceedings of Russian Scientific and Technical Conference
On traditional (copper) and fiber-optic communication lines, grounding is installed to protect the lives of workers and subscribers, as well as equipment and communication cables. For better protection, the grounding resistance should be low. Therefore, grounding is performed by a multi-electrode circuit of parallel connected single earth electrodes ...

Optimal Safety Earthing – Earth Electrode Sizing Using A Deterministic Approach

2013
In this paper a deterministic approach in the sizing of earth electrode using the permissible touch voltage criteria is presented. The deterministic approach is effectively applied in the sizing of the length of earth rod required for the safe earthing of residential and facility buildings.
