Electrical Generation Fundamentals Training System
Model Number: 490-000
A realistic power generation simulator for teaching generator operation, grid interaction, and load sharing.
Overview
Industrial facilities know how important electrical skills are to ensuring that things run smoothly and safely. What many people don’t know, however, is how diverse electrical skills can be. While basic electrical skills, such as wiring a circuit or troubleshooting a transformer, are extremely valuable and quite common, some facilities require specialized advanced electrical skills, such as those relating to power generation and managing multiple power plants on an electrical grid.
DAC Worldwide’s Electrical Generation Fundamentals Training System (490-000) represents a true simulator depicting multiple power plants on a grid. The unit basically acts as the control center for a generating station and simulates four separate generating units. The system demonstrates the principles of generator operation and represents the relationships that an operator must master in order to confidently operate generators.
Practice in paralleling machines of various sizes is easily accomplished without tying up the plant simulator. The synchroscope display includes a phase angle display, representing the phase difference between running and incoming.
A graphic representation of how load is shared, by two machines of various sizes, is shown by a house curve. The relationship between real load and reactive load is displayed by meters and by a pictorial diagram of the power triangle on the graphic display. Inductive, resistive, and capacitive loads can be turned on and off reinforcing the effects of reactive load and demonstrating how power factor can be changed.
