The European Organisation for Experimental Photogrammetric Research (OEEPE) and the International Society for Photogrammetry and Remote Sensing (ISPRS) have carried out a test on the performance of tie point extraction in automatic aerial triangulation (AAT). The aims of the test were to investigate the geometrical block stability, the accuracy of the tie points and the derived orientation para...

This paper describes the sensor modeling and the photogrammetric triangulation procedure for the TLS (Three-Line-Scanner) system. This system is a new airborne digital sensor developed by STARLABO, Tokyo, jointly with the Institute of Industrial Science, University of Tokyo. It utilizes the Three-Line-Scanner principle to capture digital image triplets in along-strip mode. The imaging system co...

Aerial multi-camera platforms typically incorporate a nadir-looking camera accompanied by further cameras that provide oblique views, potentially resulting in utmost coverage, redundancy, and accuracy even on vertical surfaces. However, issues have remained unresolved with the orientation and calibration of the resulting imagery, to two of which we present feasible solutions. First, as standard...

This paper present the analysis of load frequency control problem for interconnected power system using the PID controller. Any small sudden load change in any of the areas causes the fluctuation of the frequencies of each and every area and also there is fluctuation of power in tie line of interconnected power system. Frequency should remain nearly constant for satisfactory operation of a powe...

For the continuous evaluation of the performance of the power system, power flow solutions are essential for exhibiting suitable control actions in case of requirement. This case study presents analysis of the electrical power system of continuous process plant having its own captive generation along with the provision of the Grid connectivity. The different power system elements are modeled as...

The purpose of the paper is to analyze the transient stability of an industrial cogeneration system in Hsin-Chu Science-Based Industrial Park using ETAP software. The cogeneration system is installed two 161kV/161kV high-impendence transformers with tap-changer to connect with TPC for decreasing the short-circuit fault current and increasing the fault critical clearing time. The transient stabi...

Automatic generation control (AGC) of a power system provides power demand signals for power generators to control frequency and tie-line power flow due to the large load changes or other disturbances. Occurrence of large real power imbalance causes large frequency deviations from its nominal value which may be a threat to secure operation of power system. To avoid such situation, emergency con...
