Upfc thesis

The work presented in this thesis is concentrated on the modelling and control of the UPFC.

The overall aim is to provide effective tools for optimising the impact of the UPFC in the reinforcement of a transmission system.

Existing modelling techniques for the UPFC together with the associated control strategies have been systematically reviewed. An exact power injection model is proposed which is based on the polar representation of the UPFC parameters and includes the reactive power capability of the shunt inverter.

The influence of both the series and shunt inverters on this controlled area has been analysed. The impact of a change in the system short circuit level on the UPFC operation and the size of the feasible area has also been investigated. Three modern controllers have been designed and tested for controlling the UPFC in a power flow mode for the series part and a voltage control mode for the shunt part.

Follow us on FaceBook Due to the stress in the power system there is a chance of losing the stability following to the fault. When the fault occurs in the power system the whole system goes to severe transients.
Power system stability enhancment using UPFC damping controller - ethesis Voltage security is a crucial issue in power systems especially under heavily loaded condition.

For the former, the fuzzy rules are deduced from the relationship between the controlled power system parameters and the UPFC control variables.

The second is a simple RBFNN controller which is constructed from a single neuron and trained on-line by a gradient descent algorithm. The third controller is designed using the adaptive capabilities of neural networks to estimate and tune the fuzzy rules.

Computer simulation and experimental implementation of a UPFC using DS data acquisition board have been used to verify the proposed control strategies.The Unified Power Flow Controller (UPFC) is the versatile FACTS controller that can control up to three transmission system parameters individually or simultaneously in appropriate combinations.

The work presented in this thesis is concentrated on the modelling and control of the UPFC.

(UPFC) and Static VAr Compensator (SVC). In this thesis,the modeling and the developing of UPFC were studied in order to make better the steady state works of the power iridis-photo-restoration.com effect of UPFC on the power flow of transmission lines were analyzed mathematically and graphically. The research presented in this thesis was carried out at the Delft University of Technology (UPFC) is the most versatile device. However, the UPFC is not so-called Distributed Power Flow Controller (DPFC), is invented and presented in this thesis. The DPFC is a further development of the UPFC.
