Impact of High Voltage Direct Current Link on Transmission Line in Kurdistan Power System

open access: yesJournal of Engineering, 2022
Kurdistan power system is expanded along years ago. The electrical power is transmitted through long transmission lines. The main problem of transmission lines is active and reactive power losses. It is important to solve this issue, unless, the most of electrical energy will lost over transmission system.

Prediction of radio interference from HVDC transmission lines based on corona discharge characteristics

open access: yesHigh Voltage, 2020
Many research works have proved that it is viable to predict the radio interference (RI) of high-voltage alternating current transmission lines by corona cage test. However, it is uncertain whether the same method can be adopted for RI prediction of high-
