This paper investigates factors which influence the power quality performance of the Dhofar Power Grid, based upon the first 50MW wind farm project connection. The wind farm consists of 20×2.5 MW wind turbines and will be integrated into the 132kV Dhofar network which is connected with the Maim Interconnected System via the Petroleum Development of Oman grid. As this is the first wind farm project...
The objective of this paper is to present the methodology, approach and results of the demand forecast analysis used in the Transmission Master Plan of Oman 2014–2030. Oman Electricity Transmission Company and Tractebel Engineering analyze the challenges and review the existing load demand forecast studies used in Oman. Different studies analyze load forecasting at short to medium term. A spatialization...
The paper presents dynamic assessment of voltage and reactive power control in the Main Interconnected Transmission System (MITS) in Oman. Two case studies are considered; namely the MITS with and without temporary diesel generators. Voltage and reactive power control is achieved by optimization process to maximize reactive power margin of generating units to maintain as much as possible reserves...
This paper presents small-disturbance stability studies of the interconnected power systems of the Sultanate of Oman and the State of the United Arab Emirates. The two systems are interconnected through the existing 220 kV double circuit transmission line between Oman and Abu Dhabi leading to a rather longitudinal structure power system. The objective of the paper is to assess the inter-area oscillation...
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...
The paper presents steady-state and transient studies to assess the impact of a 200 MW Central Receiver Solar Power Plant (CRSPP) connection on the Main Interconnected Transmission System (MITS) of Oman. The CRSPP consists mainly of a central solar receiver, power tower, thousands of heliostats, molten salt storage tanks, heat exchangers, steam generator, steam turbine, synchronous generator, and...
The paper presents steady-state and transient studies to assess the impact of a 200 MW Photovoltaic Power plant (PVPP) connection on the Main Interconnected Transmission System (MITS) of Oman. The PVPP consists mainly of a large number of solar arrays, DC/DC converters, DC/AC inverters, filters, and step-up transformers. Two proposed locations are considered to connect the PVPP plant to MITS: Manah...
This paper describes the development of a digital computer model representing the main electric transmission system in Oman. A commercially available DIgSILENT power system computation package is employed. A brief description of system is given, which includes generating units, transformers, transmission lines and loads. The system is connected with a number of internal industrial plants to exchange...
The aim of this paper is to present a simulation model to predict the thermal behavior of power transformers. The model equations are established to calculate the top oil and hot spot temperatures. A simulation tool is designed to predict a transformer top oil and hot spot temperature based on the transformer manufacturer data and loading. The top oil model equation and hot spot model equation is...
