Abstract

The invention provides a compressor anti-surge control method and system. A 505/505 E controller and a DCS control system are adopted for controlling the rotating speed of a compressor, a unit starting condition, a compressor safety running mode starting condition and an anti-surge electromagnetic valve automatic control mode starting condition are arranged, and the compressor anti-surge effect isachieved. During trial run and normal production process, along with the production working condition fluctuation, the anti-surge control scheme and the compressor comprehensive safety logic controlscheme effectively prevent a unit from entering the surge area, unit safety running is ensured, meanwhile, unnecessary parking caused by surging or overload can be avoided, maintaining cost is reduced, the service life of the compressor is prolonged, process production continuity is ensured, through continuous-time production process, the anti-surge control system is stable and reliable in work, antijamming capability is high, and certain application and popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of compressor anti-surge, in particular to a compressor anti-surge control method and system. Background technique [0002] The air compressor is an important production power source of the factory. The safe and stable operation of the air compressor is a very important indicator. The key link of the air compressor control is the anti-surge control. Surge is an inherent characteristic of the compressor itself. When the exhaust pressure keeps rising and the exhaust flow keeps decreasing, the compressor will enter the surge industrial and mining operation. When the compressor enters the surge operation, its operating conditions will change drastically. The compressor will vibrate violently. If effective measures cannot be taken in time to solve the problem, the bearings and seals of the compressor will be damaged. In severe cases, the rotor and the fixed components may even rub against each other, resulting i...
