The invention discloses a data transmission method for a heterogeneous communication network of a smart substation, which includes acquiring network communication parameters of a smart substation; calculating an IP network link flow factor and a micropower wireless network link power factor; constructing a weighted hop routing cost function and Calculate the optimal service transmission path; use the optimal service transmission path for data transmission of the heterogeneous communication network of the smart substation. On the basis of comprehensive consideration of IP network and micro-power network hybrid path service transmission, the present invention proposes a weighted optimization-based transmission method for heterogeneous communication networks of smart substations, which improves the heterogeneous communication network transmission method of smart substations under the premise of ensuring service delay requirements. The communication network transmits the quality of service, and the communication speed is faster, the communication reliability is better, and the effect is better.
