Distributed Voltage and Current Control of Multi-terminal High-voltage Direct Current Transmission Systems

High-voltage direct current (HVDC) is a commonly used technology for long-distance power transmission, due to its low resistive losses and low costs. In this paper, a novel distributed controller for multi-terminal HVDC (MTDC) systems is proposed. Under certain conditions on the controller gains, it is shown to stabilize the MTDC system. The controller is shown to always keep the voltages close...

Fault Locating in High Voltage Transmission Lines Based on Harmonic Components of One-end Voltage Using Random Forests

In this paper, an approach is proposed for accurate locating of single phase faults in transmission lines using voltage signals measured at one-end. In this method, harmonic components of the voltage signals are extracted through Discrete Fourier Transform (DFT) and are normalized by a transformation. The proposed fault locator, which is designed based on Random Forests (RF) algorithm, is train...

Risks of leukaemia among residents close to high voltage transmission electric lines.

OBJECTIVES To reassess the risk of leukaemia associated with residential exposure near high voltage transmission electric lines of 49 kV and above in view of the recent publications. METHODS Through a review of papers considering the risk of leukaemia among people living near high voltage transmission lines, the combined risks of leukaemia were calculated for distances < or = 50 m and < or = ...

Implementing a GIS Methodology for Siting High Voltage Electric Transmission Lines

Standardization of high voltage electric transmission line siting methodologies, by using GIS spatial analysis tools, has great potential in helping predict and defend new optimal route corridors. A standard methodology that incorporates multiple weighted perspectives of influence can aid in the route approval by the governmental and regulating permitting entities and the support of the affecte...
