Improvement of Power System Oscillation by using Coordinated Control Plan for PSS and STATCOM Devices

This thesis work introduces the control of the coordinates of PSS and STATCOM to damp the inter field oscillations of the multi machine system. In previous eras, PSS was used as a local controller in multi machine systems to dampen such oscillations between fields. Reactive FACTS devices, such as synchronous static compensators STATCOM are taken into account and evaluated for their design of a damping controller. STATCOM is a reactive power compensator based on a voltage source converter that uses electronic power devices with stop capacity as switching devices. Its main function is to support the voltage of the bus from which it is connected to the system by providing a quick response to the delivery or absorption of reactive power. In order to dampen the power oscillations, the power oscillation damping function POD must be used, in which its output is summed with the voltage reference at the input of STATCOM.
