This training simulator is designed to demonstrate the principles of electrical power generation that, until now, have been taught using only classroom discussion or paper-based learning. The Electrical Generation Fundamentals Trainer depicts the relationships that an operator must master in order to confidently operate modern generating equipment. Practice in paralleling machines of various sizes is easily accomplished without using actual equipment or more expensive full-scale simulators.

In addition to a complete array of analog meters, as typically seen in a control room, a gas plasma display is used to dynamically represent the abstract concepts of electrical generation. A synchroscope display and a phase angle display represent the phase difference between running and incoming sources. A graphic representation of how load is shared by two machines of different sizes is shown using a generator characteristics curve. The relationship between real load and reactive load is displayed using meters and by a pictorial diagram of the power triangle on the gas plasma display.

A variety of inductive, resistive, and capacitive loads can be turned on and off, reinforcing the effects of reactive load and how power factor can change. The trainer easily supports instructor demonstration, student practical exercises, and self-study programs. In use by many utilities, independent power producers, and grid operators, this inexpensive, yet informative, training device will make training in basic power plant concepts more informative and productive.
