Voltge & Reactive Power Control In Oman Transmission System, Omar H. Abdalla, Rashid Al-Badwawi, Hilal Al-Hadi, Hisham Al-Riyami, Ahmed Al-Nadabi, Karim Karoui, Ariadne Szekut
Voltge & Reactive Power Control In Oman Transmission System, Omar H. Abdalla, Rashid Al-Badwawi, Hilal Al-Hadi, Hisham Al-Riyami, Ahmed Al-Nadabi, Karim Karoui, Ariadne Szekut

The paper presents voltage and reactive power control in the Main Interconnected Transmission System (MITS) in the Sultanate of Oman. The objective is to improve voltage profile at substations supplying distribution companies and directly connected bulk customer. An objective function is used to maximize reactive power margin of generating units to maintain as much as possible reserves on different generators. The control parameters include existing voltage and reactive power control means, e.g. settings of generators’ excitation/AVR, transformer tap-changing, and capacitor bank switching. The constraints include operational limits of the above control devices in addition to allowable limits of busbar voltages, …
Weather-Based Ampacity Of Overhead Transmission Lines, Omar H. Abdalla, Rashid Al-Badwawi, Hilal Al-Hadi, Hisham Al-Riyami, Ahmed Al-Nadabi
Weather-Based Ampacity Of Overhead Transmission Lines, Omar H. Abdalla, Rashid Al-Badwawi, Hilal Al-Hadi, Hisham Al-Riyami, Ahmed Al-Nadabi
Omar H. Abdalla
The paper concerns with the determination of Weather-Based Ampacity (WBA) of overhead line conductors in the Main Interconnected Transmission System (MITS) of Oman. The objective is to exploit the available capacity of existing overhead transmission lines, thus reducing investments in replacing conductors or constructing new circuits. Conductor parameters and weather data are collected to calculate the thermal rating of the of transmission lines. The weather data collected from the Directorate General of Meteorology and Air Navigation includes hourly wind speed and temperature over several years and locations in Oman. Analysis of Oman weather data has shown that there is an …
