Comparison between permanent magnet generators and electrically excited generators

Comparison Between Permanent Magnet Generators And Electrically Excited Generators 1 Permanent magnet generators can run at variable speeds. Electrically excited generators can only run at a constant speed. When the speed varies greatly, the AVR of electrically excited generators will desperately increase the excitation current, which will burn up the excitation coil to a certain […]

Why build micro-hydropower

Flowing and falling water has potential energy that can be converted into electricity through hydroelectric systems. The fall of rivers generates huge electricity to supply to thousands of households through large hydropower hubs; similarly, small rivers, streams, and the flowing and falling water formed by gushing springs can also build micro-hydropower systems (referred to as
