Anti-surge control method for blast furnace blower

The invention discloses an anti-surge control method for a blast furnace blower. According to anti-surge control method, the thought of optimizing an anti-surge control loop by utilizing the analysisof measurement data of a blast furnace side air supply pipeline is provided for the first time to overcome the disturbance of abnormal working conditions of the blast furnace side of the air blower, asignificant interference factor which causes the surge to occur in the measurement parameters is found out, a anti-surge regulator feedforward mathematical model is provided, an interference amount is directly introduced to an anti-surge control system after being calculated, so that the influence of an interference factor on a blower set is overcome in advance by the regulator loop on the basisof original closed-loop feedback adjustment, and a more timely and accurate adjusting effect is obtained. 本发明涉及种高炉鼓风机防喘振控制方法，为使鼓风机克服高炉侧异常工况的扰动，第次提出了利用高炉侧送风管道测量数据的分析来优化防喘控制回路的思路，寻找测量参数中导致喘振发生的显著干扰因子，提供种防喘振调节器前馈数学模型，将干扰量经过计算后直接引入
