Engineering Reports, Volume 8, Issue 6, June 2026.Due to complex wind farm conditions, a coordinated control system was designed. It manages DC power surges during AC faults by temporarily storing excess energy and regulating voltages. This strategy optimizes unbalanced power and enables effective fault recovery, resulting in minimal voltage fluctuations and superior performance.

HVDC-Transmission Line Model for Transient Simulation Purposes
IFAC Proceedings Volumes, 1992 Abstract A lumped bipolair HVDC-transmission line model, based on least squares fitting of orthogonal polynomials, which are space dependent, and have time dependent coefficients, is presented and examined in this paper. The model enables the line voltage and current to be approximately determined for arbitrary points along the line and at arbitrary ...

Engineering Reports, Volume 8, Issue 6, June 2026.Typical configuration of Huangshan Scenic Area. ABSTRACT To cope with the supply and demand imbalance challenge caused by the surge in energy demand in tourism‐intensive areas and the high volatility of renewable energy, this paper aims to construct a collaborative scheduling optimization model based on graph neural networks (GNNs). The model abstracts

Ann based Shortcoming Area in HVDC Transmission Line
International Journal of Innovative Technology and Exploring Engineering, 2019 This paper is to ponder the use of Neural systems for shortcoming discovery and area in HVDC framework. The proposed Neural system learns examples and relationship on transient information. The Back-propagation algorithm has the ability to match map complex and nonlinear input - output behavior.

High Voltage, Volume 11, Issue 3, Page 646-655, June 2026.ABSTRACT The harmonic current and vibration of a converter transformer are effective pieces of information for detecting mechanical faults in the winding. In this paper, the ratio of vibration acceleration to the current squared is defined as the vibration frequency response function (VFRF) of the winding, and then, a novel online vibration frequency ...
