This paper addresses the design procedure of a fuzzy logic-based adaptive approach for DFIGs to enhance automatic generation control (AGC) capabilities and provide better dynamic responses in multi-area power systems. In doing so, a proportional-integral (PI) controller is employed in DFIG structure to control the governor speed of wind turbine. At the first stage, the adjustable parameters of ...

In the XFLEX HYDRO Vogelgrun demonstrator, a run-of-river hydropower plant, hybridization of one turbine-generator unit with battery energy storage system is being investigated. This paper describes integration methodology hybrid control algorithm without replacing existing speed governor unit. Furthermore, comparison performances non-hybrid and discussed, first experiences gained during operat...

Previous panel papers have described testing for NERC and WSCC compliance [A] and testing and tuning of governors for compliance and island-mode performance [B]. This paper presents experience with testing of gas turbine plants for NERC and WSCC compliance. Testing has been performed on older analog-electronic and new digital-electronic units. The level of detail used in modeling and model avai...

In this paper, we propose a right-to-left dependency grammar parsing method for languages in which a governor appears after its modiier like Korean and Japanese. Unlike conventional left-to-right parsers, this parsing method can take advantage of the governor post-positioning property of such languages to reduce the size of search space by using the idea of a headable path. A headable path is a...

This paper presents a novel adaptive reference governor for robust tracking control in constrained linear systems with bounded disturbances. The proposed reference governor achieves a performance improvement over the existing reference governors by virtue of its added feature: adaptability. The design of such an adaptive reference governor involves a nonlinear non-deterministic polynomial time ...

The paper addresses the problem of vehicle rollover avoidance using reference governors applied to modify the driver steering input in vehicles with an active steering system. Several reference governor designs are presented and tested with a detailed nonlinear simulation model. The vehicle dynamics are highly nonlinear for large steering angles, including the conditions where the vehicle appro...

A new approach to manage actuator redundancy in the presence of faults is proposed based on reliability indicators and a reference governor. The aim is to preserve the health of the actuators and the availability of the system both in the nominal behavior and in the presence of actuator faults. The use of reference governor control allocation is a solution to distribute the control efforts amon...

The purpose of present paper was to examine the relationship between central bank independence and inflation rate in Iran over 1960-2008. First, central bank independence has been accomplished through three indices including legal and real CBI indices and turnover rate of central bank governor index. Then, Augmented Dickey-Fuller test for model stationary of variables has been done by applying ...

The purpose of this paper is to present an efficient converter circuit used to drive switched reluctance motors. It uses the C-dump topology in which the trapped energy in the phase windings is returned to the supply capacitor to be used in the following strokes. In addition to the C-dump topology, it uses two extra feedbacks. One comes from a governor mounted on the shaft of motor which contro...

This paper investigates governor design by reduced-order sliding mode for a hydropower plant with an upstream surge tank. The governing system is made up of a tunnel, a surge tank, a penstock, a wicket gate and servomechanism, a governor, a hydro-turbine and a grid. Concerning the components of the governing system, their mathematic models are established. Then, these models are interconnected ...
