Annotation: There are various types of electrical equipment used in the extraction of oil at the Rumaila field, with an average voltage of 11 kV and a low voltage of 0.4 kV. The most common elements in this class are transformers and reactors, engines and gas discharge lamps. All of this equipment consumes reactive power and reduces the value of the power factor. (Power factor is the ratio of kW to kVA). The closer the power factor to the maximum possible value of 1, the greater the benefit for the consumer and supplier. In case of low power factor, the current will be increased, and this high current will lead to (large line losses, an increase in the nominal total power of kVA and overhaul dimensions of electrical equipment, deterioration in voltage regulation process and an increase in voltage drop, a decrease in efficiency).Power factor improvement allows the use of smaller transformers, switchgear and cables, etc. as well as reducing power losses and voltage drop in an installation. Improving the power factor of an installation requires a bank of capacitors which acts as a source of reactive energy. These arrangements provide reactive energy compensation. In Rumila, An improvement of the power factor of an installation presents several technical and economic advantages, notably in the reduction of electricity bills, we save (685.854.007 Iraqi Dinar= 550.000 $) for one month . All this work takes 6 to 12 month. . Optimize the performance of electrical equipment in gas separation stations (degassing station DS) and electrical submersible pumps of oil equipment for oil Rumaila field.

This paper deals with modeling and simulation of current Source Inverter (CSI) based Static Series Compensator (SSC). Series compensation is the basic foundation for power electronics based compensators. Its highly effective in controlling the desired voltage profile along the transmission line interconnecting two buses of the ac system. An eight bus system is chosen as the test system. The system is modeled and simulated using MATLAB/SIMULINK. Voltage sag is created by increase in load. Generally voltage source inverter(VSI) is used as a Static Shunt Compensators or STATCOM to compensate for voltage deviations at a bus. This paper presents the investigations into application of a CSI as a Series Compensator in a multi-machine system to compensate for voltage deviations. The performance of CSI is compared with that of a VSI and a Push Pull converter connected in series. The results are presented for an eight bus system.
