- TL;DR Summary
- This generator G1 is connected to an AVR, what I don't understand is why the excitation is separately by voltage G3 and current G2.
Any explications please
Thanks
A generator excitation method is a technique used to provide the necessary electrical energy to the rotor of a generator in order to produce electricity. This is essential for the functioning of a generator as it creates a magnetic field that interacts with the stator to produce electricity.
A generator excitation method is important because it is the key factor in generating electricity. Without a proper excitation method, the generator will not produce any electrical energy, rendering it useless. It is also important for maintaining the stability and efficiency of the generator.
There are three main types of generator excitation methods: permanent magnet, self-excited, and separately excited. Permanent magnet generators use permanent magnets to create a magnetic field, self-excited generators use residual magnetism to start the excitation process, and separately excited generators use an external power source to provide the excitation energy.
The choice of generator excitation method depends on various factors such as the type of generator, its size, and the intended use. It is best to consult with a professional or refer to the manufacturer's guidelines to determine the most suitable excitation method for your specific needs.
Some common issues with generator excitation methods include over-excitation, under-excitation, and voltage regulation problems. These can be caused by factors such as incorrect settings, faulty equipment, or inadequate power supply. Regular maintenance and proper troubleshooting can help prevent and resolve these issues.
