Small-signal models or HIL (Hardware-In-the-Loop) simulation results testing the stability of 15 kV / 16.7 Hz networks. Research Papers: Studies on the historical transition from
Lower frequencies reduce reactive power production in AC cables, allowing for active power transmission over longer distances with fewer losses.
This frequency is standard for major European operators like (Germany), ÖBB (Austria), and SBB (Switzerland).
Early electric locomotives used "brush-type" AC/DC motors that operated much more efficiently at lower frequencies.

Hz to the modern 16.7 Hz standard to prevent synchronism issues in rotary converters.
