Optimization method for air compressor system of iron and steel plant

The invention discloses an optimization method for an air compressor system of an iron and steel plant. The optimization method comprises the following steps of: building compressed air pressure and flow demand models of each user; reading real-time data of compressed air of each user, optimizing the compressed air pressure and flow demand models of each user according to the real-time data of thecompressed air of each user, and giving a pressure set value of a compressed air pipe network; setting the running state of an air compressor of each air compressor station of the air compressor system according to the pressure set value of the compressed air pipe network; judging whether the air compressor system is in an optimal state or not, and maintaining the air compressor system to run inthe optimal state if the air compressor system is in the optimal state; otherwise, re-giving a pressure set value of the compressed air pipe network until the air compressor system is judged to be inthe optimal state, and main
