“…The presented study considers several typical synchronous generators which are connected to 500 kV EHV Jamali System, Indonesia. The study was carried out through the "hybrid" method by combination both unbalanced loadflow under EDSA 2000 to analyze the grid and to determine the inputs of the test generator and the rotor's qd0 reference frame of synchronous generator model to substitute the loadflow generator's model [16][17]. The verification of the proposed model was checked by comparing it with a Tecquiment NE9070 simulator.…”

The purpose of this study is to design and develop a synchronous generator virtual laboratory for undergraduate student courses, which can be treated as an accessorial tool for enhancing instruction. Firstly, the study reviews the general concept and algorithm of synchronous generator model. Secondly, the simulation method of this system is discussed. Finally, the paper introduces its example and analysis. One of the major objectives of this project is the dynamics of synchronous generators connected to the 500 kV EHV Jamali (Jawa-Madura-Bali) System under unbalanced steady state condition that could be modeled as a balanced synchronous generator’s model with unbalanced voltage inputs. The balanced synchronous generator model based on the rotor’s qd0 reference frame was chosen to substitute generator’s model embeded in loadflow analysis. The verification of the proposed generator’s model was checked by comparing it with a PSS Tecquiment NE9070 simulator. The unbalanced voltage inputs of generator were derived utilizing the loadflow analysis by determining the phase and sequence currents, and average bus voltages of the 500 kV EHV Jamali grid considering unbalanced portion variations. Meanwhile, the load locations having significant effect on the test generators are obtained by using the electricity tracing method. The developed virtual laboratory with a given example demonstrated the usefulness of the tool for studying synchronous generator under unbalanced steady-state operation.

This paper presents an analysis of the oscillations caused by unbalanced loads in salient pole synchronous generators that operate in isolation under steady state. The oscillatory disturbances, arising from the second-order harmonics, may have or have the potential to cause electromechanical damage to the salient pole synchronous generator. In this paper, the goal is to identify and quantify the magnitude of the electromagnetic torque, which assumes an oscillatory form due to the current component from the negative sequence, caused by unbalanced currents. The self-same analysis was included for second-harmonic voltage oscillations in the qd0 domain, the currents induced on the damper windings together with the oscillation of the load angle and on the field current. These oscillations situated on the synchronous generator are analyzed for a degree of voltage unbalance close to 2% which is an acceptable value according to international regulations for power supply from distribution networks, and this same degree of tolerated voltage unbalance will be used herein for isolated synchronous generators.

“…With the intention of helping to increase the knowledge about the dynamic behavior of synchronous generator after small disturbances, this study presents a thorough study concerning the dynamic behavior of unbalanced transient state synchronous generator model. The work is mainly carried out through nonlinear simulations under Matlab-Simulink [13][14][15][16][17][18], where the unbalanced power systems are calculated through the EDSA 2000 [19].…”

Modern maritime on-board communications have to be improved for safety and security. Current technology provides ease and expediency together to the crew and passengers with the help of ubiquitous technologies. Making use of Wireless Sensor Network (WSN) on board is a current custom of implementing ubiquitous technology for ships as it is important for an on-board communication system which provides reliability and flexibility for handling emergency situations. Two key phases of this scheme are: merging different on-board communiqué networks into a fusion system and enabling the cooperation between them; smoothly incorporating these networks with a consideration of backward compatibility, ease of deployment and association to shore via Internet. A combined integration move towards is selected based on comprehensive analysis.
