This paper introduced the test, calculation and fitting of the surge curve of the coal gas compressor and anti-surge control strategy.The anti-surge control system realized many functions such as creating anti-surge curve, dynamic adjust control deviation of the anti-surge control, the switch of the auto/manual operation, the dissymmetry output, fast response and the status indication of anti-surge control.The practice proved the system control accuracy is high, the function is stable, operating simple, keep the view and understand easily.
