The invention relates to a distributed new energy running data encryption, compression and transmission method based on an LZW (Lempel-Ziv-Welch) algorithm. The method comprises the following steps: performing compression and encryption by adopting the LZW algorithm after data acquisition according to the characteristic of continuous change of distributed new energy running data; uploading data; and decrypting by adopting the LZW algorithm at a data receiving end to restore original data. Through adoption of the method, the transmission safety of data can be ensured effectively, data are prevented from being intercepted and used by other people, and malicious data attack by other people can be effectively eliminated. Meanwhile, through adoption of the method, the amount of data needing to be transmitted can be reduced, the data transmission speed is increased greatly, and the cost of public network transmission is reduced.
