Abstract:
Generator test benches and back-to-back testing systems and methods are disclosed. A test bench (110) may comprise a single fixed structure and a shaft (132). The single fixed structure may include a common base (160) fixed to the ground and a hollow body (115) with a central pillar (117) connecting them. The shaft may be arranged inside the hollow body and may have a first end extending beyond a first opening and a second end extending beyond a second opening of the hollow body. The shaft may be connectable to rotors (124A, 124B) of two generators (120A, 120B). The single fixed structure may be connectable to the stators of the generators (122A, 122B).
