Abstract

The invention discloses a data transmission method for a heterogeneous communication network of a smart substation. The method comprises the following steps: acquiring network communication parameters of the smart substation; calculating an IP network link flow factor and a micro-power wireless network link power factor; constructing a weighted hop count routing cost function and calculating to obtain an optimal service transmission path; and performing data transmission of the heterogeneous communication network of the smart substation by adopting the optimal service transmission path. On the basis of comprehensively considering the mixed path service transmission of the IP network and the micropower network, the invention provides the intelligent substation heterogeneous communication network transmission method based on weighted optimization, so that the transmission service quality of the intelligent substation heterogeneous communication network is improved on the premise of ensuring the service time delay requirement; and the communication speed is higher, the communication reliability is better, and the effect is better.

Description

technical field [0001] The invention belongs to the field of power grid automation, and in particular relates to a data transmission method for a heterogeneous communication network of a smart substation. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. Therefore, the stable and reliable operation of the power system has become one of the most important tasks of the power system. [0003] In recent years, with the rapid development of smart substations, the scale of the power system has continued to grow, and higher requirements have been placed on smart substations. The communication network related to smart energy stations is usually a heterogeneous communication network including IP network and micro-power wireless network. Micropowe...
