The UPFC parameters in order to increase voltage level and decrease power losses are adjusted. Currently, she is an assistant professor of Sadjad Institute for Higher Education. Using this model, two virtual buses are added to the network. The maximum value of injected voltage amplitude p. Izadpanah Tous, and M. The studies are carried out with and without fault consideration in SMIB system.

The UPFC is the shunt-series device that provides power flow control together with separate voltage control. Figure 4, shows the proposed model for the UPFC. Each of input variables are classified by Input membership function consists of trapezoidalmembership function and triangular membership function, described in Fig. The shunt converter is mainly used to supply active power demand of the series converter via a common DC link. The parameters of CPSS convectional power systemstabilizer are calculated Based on the linearized model of the powersystem[1].

The model is simple and beneficial in understanding the UPFC impact on the power system. Computer simulation and experimental implementation of a UPFC using DS data acquisition board modelliing been used to verify the proposed control strategies.

The changes of power are shown in Table 1. Each component is explained as follows: The output membership function also consists of triangular membership function and rules described in Fig. You can help adding them by using this form. It is compulsory to analyze its effect of UPFC on power system network when the fault occurs in kpfc power system and therefore whole system goes to severe transients.


Test results using different power system models are presented throughout the thesis to illustrate the effectiveness of Unified Modelking Flow Controller.

Injection model of the UPFC [3]. In parliamentary law to providing stabilizer signal, the output of obtained model reference ofpower system is compared with output of the actual power system and the error signal is fed to afuzzy controller.

The work presented in this thesis is concentrated on the modelling and control of the UPFC. Search the history of over billion web pages on the Internet. See general information about how to correct material in RePEc.

Investigation of advanced control for the unified power flow controller UPFC. Reactive power is injected in sending bus order to achieve the specified voltage magnitude. The parameters of CPSS convectional power systemstabilizer uptc calculated Based on the linearized model of the powersystem[1].

Currently, he has worked at the Khavaran Nasr Company. Several papers can be found on development of UPFC steady state and dynamic models [5] – [8].
