摘要

Drive control software protects compressors from Norwegian winters, explain Harald Fretheim (ABB Oil, Gas and Chemical - Norway) and Sture Van De Moortel (ABB Robotics and Motion Division, Drives - Switzerland). A variable speed drive control algorithm ensures large compressors do not stop operating after an electrical network disturbance. This results in guaranteed process uptime, improved energy efficiency and increased motor life.
