With the growing number of severe system disturbances and blackouts around world, controlled separation is becoming an increasingly important integrity protection scheme (SIPS) to save electric power from a complete or partial disintegration. A successful splitting approach should at least tackle following two well-known interrelated problems: “when split?” “where split?”. Multiple previous pub...

This paper investigates the preliminary sizing of generator set to design electrical system at the early phase of a project, dynamic behavior of generator-unit, as well as induction motors, during start-up of the induction motor drives fed from emergency generator unit. The information in this paper simplifies generator set selection and eliminates common errors in selection. It covers load est...

This paper presents the application of the Linear Quadretic Gaussian (LQG) controller for voltage and frequency regulation of an isolated hybrid wind-diesel scheme. The scheme essentially consists of a vertical axis wind turbine driving a self-excited induction generator connected via an asynchronous (AC-DC-AC) link to a synchronous generator driven by a diesel engine. The synchronous generator...

A Bessel generator multiplier for a unitary system is a bounded linear operator that sends Bessel generator vectors to Bessel generator vectors. We characterize some special (but useful) Bessel generator multipliers for the unitary systems that are ordered products of two unitary groups. These include the wavelet and the Gabor unitary systems. We also provide a detailed exposition of some of th...

—This document presents an introduction of two commonly used power system differential algebraic equations for studying electromechanical oscillation and transient stability. Two types of generator models are used to formulate the power system model, respectively: the second-order classical model and the fourth-order generator model. An example is provided on the IEEE 9-bus system.

We introduce the architecture and organizational principles of a system capable of analyzing and composing arguments that are persuasive for particular interlocutors. The main components of this system are an Argument Generator, Analyzer and Strategist. The Generator produces arguments that aim to convince a user of the correctness of a goal proposition. Since the generated arguments are tailor...

In this paper we address two important issues in generating spoken language within a multimedia system: the design of a speech generator to facilitate coordination between media, and extensions to the functionality of a written language generation system to produce natural speech output. We demonstrate how a speech generator can produce information that allows for temporal coordination between ...

In this paper a variable speed generating unit is considered, equipped with permanent magnet generator. The system analysis involves appropriate models for the generator, the static converter and the grid. Moreover, an asynchronous generator mounted on the same rotor with dump loads ensures braking actions and management of the active power produced. The modelling of the generator and power ele...

Plug-in hybrid electric vehicles (PHEVs) have been promoted as a potential technology to reduce emissions of greenhouse gases and other pollutants by using electricity instead of petroleum, and byimproving electric system efficiency by providing vehicle-to-grid (V2G) services. We use an electric power system model to explicitly evaluate the change in generator dispatches resulting from PHEV dep...
