摘要
Methods, systems and controllers for detecting a surge event based on pattern of evolution of a discharge pressure of a compressor, and for relocating a surge margin relative to a surge parameter value recorded at the beginning of the surge event are provided. A controller has an interface configured to receive values of the discharge pressure from a compressor, and to output signals and alarms, a surge event detection unit connected to the interface and configured to detect a surge event in the compressor based on evolutions of the discharge pressure, a rate of the discharge pressure and a rate change of the rate, and a surge margin relocation unit connected to the surge event detection unit and the interface, and configured to relocate a surge margin relative to a surge parameter value recorded at a beginning of the surge event.
