In this paper, the first system of the IEEE second benchmark model (SBM) for subsynchronous resonance (SSR) studies is analyzed using the bifurcation theory. A nonlinear model for the SBM which consists of a synchronous generator connected to an infinite busbar through two parallel transmission lines, one of which is equipped with a series capacitor, has been developed in MATLAB. Generator damp...

This paper investigates performance of Fuzzy Supervisory Controller (FSC) in control of power converters. A FSC module is added to conventional narrow bandwidth voltage regulator in Power Factor Corrected (PFC), Voltage Source Converter (VSC) to improve DC bus voltage regulation. PFC converter is selected for this work as conventional design of the PFC converter requires narrow bandwidth DC bus...

This paper describes the transient behaviour of a doubly-fed induction generator (DFIG) driven by wind turbine after its disconnection from the grid. The induction machine runs at a specific speed with the stator disconnected from the grid (Is=0), the rotor is suddenly excited with slip-frequency voltages derived from voltage regulators so as to produce commended open-circuit stator terminal vo...

This paper presents a simple class AB buffer which is suitable for low-voltage (1.5 V) applications. The proposed buffer uses an adaptive load to reduce the sensitivity of the quiescent current to the process variation. The main feature of this scheme is its simplicity. The circuit was fabricated in a 2.0 m digital CMOS process. Experimental results demonstrate that the buffer can operate with ...

This paper deals with the performance analysis of static compensator (STATCOM) based voltage regulator for self excited induction generators (SEIGs) supplying balanced/unbalanced and linear/non linear loads. A threephase insulated gate bipolar transistor (IGBT) based current controlled voltage source inverter (CC-VSI) known as STATCOM is used for harmonic elimination. It also provides the requi...

In Spain, electrical industries do not charge the energy bill directly to the nal user, but they share the ownership of an enterprise (called R.E.E., Red El ectrica de Espa~ na) which gets all payments and then distributes them according to some complex criteria (amount of power generation of every company, number of customers, etc.) Recently, some of these companies have asked to redistribute ...

Pelepasan beban secara tiba-tiba seperti saat terjadi hubung singkat dapat menghasilkan osilasi pada sistem tenaga listrik. Oleh karena itu, diperlukan suatu peralatan untuk mempercepat redaman tersebut. Salah satunya adalah dengan menggunakan PSS. Dalam melakukan pengaturan parameter dari PSS tersebut,diperlukan metode sehingga beroperasi optimal dalam menstabilkan sistem. penelitian ini, Part...

Abstract A novel control strategy of synchronous compensators and converters is proposed to increase the ability line commutated converter (LCC) based HVDC systems successfully recover from commutation failures (CFs). The dynamic var support one most important factors, which impact process. Many have been implemented enhance transient voltage stability for improving CF recovery performance. How...
