A Complete Analysis for Detection and Localization of Partial Discharges in XLPE Cables, Power Transformers and Generators

مهندسی مخابرات جنوب
The failures of the power system are caused by insulation damages of HV apparatus including transformers, HV cables and generators. They are expensive. In the beginning, insulation failures occure in limited regions of insulation, which is called partial

Primary Frequency Reserve Providing Strategy of Doubly-Fed Induction Generator Wind Generation Using Rotor Inertia Characteristics

IEEE Access
For power grids with a high penetration level of wind power generation, stochastic wind speed variation adversely affects the frequency stability. A variable-speed wind turbine generator would deloads its output by shifting the power operating point to ...

A novel directional pilot protection method for EHV transmission lines based on S-transform and SVM

Discover Applied Sciences
To address the issues of insufficient reliability and low sensitivity of traveling-wave (TW)-based protection caused by fault condition attributes, i.e., fault resistance and fault angle, this paper proposes a novel directional pilot protection method ...
