System for providing a high-fidelity visual display coordinated with a full-scope simulation of a complex system and method of using same for training and practice

Abstract: Control panels of a simulated complex system are displayed as a texture mask over a three-dimensional visual representation of an environment in which the complex system is operating. The three-dimensional visual representation is displayed in an inactive window to a user practicing or training on the simulated system. An active window underlying the visual display is used to track user inputs to the control panels. Smart graphics translate the user inputs into data elements that are sent to a full-scope simulation, and simulation conditions are returned and used to update the display of the control panels and the visual representation of the environment.

Compressor with intercooling

Abstract: A gas turbine has a mainly axial-flow two-stage compressor (1A,1B), with an intercooler (5). It also has at least one combustion chamber (7,8), one or more turbines (2A,2B), and a recuperator (6) in which the compressor air is heated to the inlet temperature in the combustion chamber (7). At least a first compressor component (1A) has water injectors (12), and the intercooler has equipment for water recuperation (13). The latter is connected to the injectors via a delivery pump (14). The injectors may be arranged in the compressor in the plane of the stator blades, and may also be arranged over the entire height of the compressor duct.

Object-oriented system for monitoring from the work-station to the boardroom

Abstract: Systems and methods for visually displaying real-time enterprise management information over all levels of a corporate organizational structure of an enterprise An application integration platform receives plural types of data from manufacturing and information systems within the enterprise and analyzes the plural types of data to determine key performance indicators A process control server receives manufacturing data from at least one work center and forwards the manufacturing data to the application integration platform A database contains information related to manufacturing processes performed at the at least one work center A graphical user interface that interfaces with the application integration platform to provide a visual display of the key performance indicators in accordance with the class of user interacting therewith The levels of the corporate organizational structure are modeled as objects having methods and variables In addition, the objects may be created using an organizational hierarchical structure of the enterprise to be monitored together with respective states and behaviors of components within each level of the corporate structure

A Novel Approach to Interarea Oscillation Damping by Unified Power Flow Controllers Utilizing Ultracapacitors

Abstract: This paper discusses a novel approach for damping interarea oscillations in a bulk power network using multiple unified power flow controllers (UPFCs) utilizing ultracapacitors, also known more generally as electrochemical capacitors (ECs). In this paper, a new control is introduced to mitigate interarea oscillations by directly controlling the UPFCs' sending and receiving bus voltages that better utilizes the stored energy in the ECs. The results of this controller are compared with and without ECs. The proposed control provides better interarea oscillation mitigation when applied to multiple UPFCs in the 118-bus IEEE test system.

Method and device for calibration of movement axes of an industrial robot

Abstract: In a calibration method for an industrial robot (2-6), a calibration tool (8) supported by the robot hand (6) is brought into contact a spherical calibration body (7) with a known radius. Thereafter, the output signals from the position transducers of the robot axes are read and stored. This method is repeated a plurality of times with different robot configurations. Thereafter, the calibration parameters of the robot are calculated starting from the kinematic equations of the robot, a model of the relationship between axial position and position transducer signal, the known radius of the calibration body, and the read and stored position transducer signals.
