In this paper, a one-dimensional model for the simulation of surge is used to study the dynamic behavior of a compression station. The station consists of a main line where the compressor operates and of a secondary line which allows the recirculation of the working fluid in order to prevent surge occurrence. With respect to the three maneuvers considered (from startup to normal operation, emergency shutdown and operating point variation), a sensitivity analysis is carried out to evaluate the influence of: • working fluid (methane and biogas); • surge margin value; • presence of a suitable PID controller; • presence of a cooler along the main flow line; • compressor driver (gas turbine and electric motor).
