Intelligent Control of Starting Power of Air Compressor Units Under Oscillation and Instantaneous Overload Conditions
In order to solve the problems of oscillation and instantaneous power overload in the energy storage con-verter during the start-up process of industrial air compressor units,resulting in power imbalance,a stable automatic control method for the start-up power of air compressor units is designed.According to the variation law of the pow-er factor angle of the air compressor unit during the soft start process of the air compressor,the discrete degree of the collected power factor angle is divided using the variable point grouping method.The power factor angle closed-loop feedback is used to compensate for the triggering angle of the dynamic process and solve the oscillation prob-lem.In order to prevent the overload problem of energy storage converters,constant power control is introduced to maintain the stability of output power by calculating indicators such as active power loss,gain,and energy loss.By adjusting stability control parameters and implementing adaptive mode conversion,automatic control of stable power output for air compressor units under different operating conditions is achieved.Example analysis shows that the de-signed method has high precision in power stabilization control,rapid response,and significant application advantages.
