The invention relates to a gas long-distance delivery pipeline, a gas long-distance delivery pipeline optimizing device and a gas long-distance delivery pipeline optimizing method on basis of particle swarm optimization algorithm. The long delivery pipeline comprises a front station field, a middle station field and a rear station field, which are connected through pipelines, and compressors are arranged in the station fields. The gas long-distance delivery pipeline optimizing method includes the following steps: a, collecting scheduled delivery capacity and basic physical parameters of the pipelines; b, establishing a compressor starting scheme set, randomly initializing running states of the compressor in each scheme; c, computing total energy consumption, access pressure of the station fields and throttling loss of the pipelines at the initialized state; d, computing the historically optimal starting scheme of particles in each compressor starting scheme; e, computing the historically optimal starting sche
