At a certain power plant, the #5 unit underwent an integrated air‑induction and boost‑air modification. Two sets of ATA high‑voltage soft‑starter cabinets were installed to drive 8,400 kW axial fans, and on May 13, 2026, the load‑testing commissioning was successfully completed in a single attempt. The startup was smooth, with no mechanical shock or alarms, and the bypass switching achieved zero‑current impact; the plant’s site team gave their full approval.

The Saudi project faces a triple challenge: extreme high temperatures and sandstorms, a 60-Hz grid, and the weak grid conditions typical of diesel generator sets. Otto soft starters, leveraging thyristor phase‑shift control and an adaptive current‑ramp algorithm, precisely limit inrush current, prevent voltage dips, and safeguard the generator set. All equipment achieved successful full‑load startup on the first attempt, with zero failures and zero rework, demonstrating key advantages such as wide‑band frequency and voltage tolerance, robust starting under weak‑grid conditions, and exceptional durability in harsh environments.

In high-energy-consuming industries such as steel, petrochemicals, and mining, the startup of high-power motors has always been a critical challenge—characterized by significant inrush currents, severe voltage drops in the power grid, and a high risk of mechanical damage. These issues not only affect production efficiency but also pose serious threats to equipment safety. Recently, Changsha ATA's independently developed ATAF-H10/18000 medium- and high-voltage soft-starter device for energy-saving applications was successfully deployed in a large-scale air separation and gas supply project at a major steel enterprise. With its outstanding performance, the device achieved three major breakthroughs: "smooth startup, stable grid operation, and robust mechanical protection," setting a new industry benchmark.
