In order to solve the abnormal operation of air separation plant caused by power swing,an anti power swing method based on circuit control is proposed for air separation plant.According to the actual situation of the air separation unit during operation,the operation process of the unit under the transient voltage drop state is calculated to obtain the transient voltage of the air separation unit under the power swing state.Introduce circuit control technology,connect the circuit connected to the device with the battery SW switch,and optimize the structure of the voltage support device.The anti shaking method design of the air separation plant is completed by compensating the running voltage of the air separation plant.The results of comparative experiments show that the anti sloshing method designed for the air separation plant can meet the anti sloshing demand of the air separation plant in operation and ensure the stable,safe and continuous operation of the plant.
