This course begins with an overview of generator construction features. The purpose of the generator is to receive the rotating mechanical energy and convert this into usable electricity at a specified terminal voltage and frequency. Care must be taken to keep its temperature rise below established limits. We will then explore rotors and DC excitation.
Next, we delve into generation fundamentals, such as electromagnetic induction and stator windings, before looking at controlling generator power output. In the principle of electromagnetic induction, magnetic lines of force move across the conductor and in doing so creates a voltage in the conductor. The generator is connected to the power system through a three phase circuit breaker where several generators are connected in parallel they will feed into a common bus each with their own individual breaker. The kilowatt or megawatt output of the generator is known as active power and this is the power which actually does useful work for the consumer.
The course then explores load sharing, covering power angle, speed droop, and load limiters. The load angle or power angle is the relative angle between the induced to voltage due to the rotor and the stator terminal voltage which is dependent upon the power system.
Our course concludes with an overview of reactive power. The term MEGAVAR stands for Mega Volt Amperes Reactive. It is actually the unit for reactive power.

End of Course Instructions
Upon successful completion of the course and the accompanying survey, you will get your certificate and, if appropriate, have your success reported to the relevant regulatory body.
NERC CE: If you selected this option at the course launch, your credits will automatically be reported for NERC CE through the NERC SOCCED reporting tool. In case of reporting failure, your credits would be manually reported within 48 hours. It is important to provide the correct License Number in order to obtain the completion certificate and get reported. You can also use this Certificate for PDH Reporting and reporting to any other Regulator (example PJM, etc.).
RCEP: If you selected this option at the course launch, you will NOT receive a certificate directly from the training page. Instead, your credits will be reported to RCEP and you would receive a certificate from them through email.
360training: If you selected this option at the course launch, you are seeking NO credit reporting. The training you are taking is for professional development only. You will receive a generic 360 certificate.
As each lesson concludes, you will be required to complete a knowledge check in order to progress to the next lesson.
