Abstract：Optical fiber composite low-voltage cable is an organic combination of optical fiber and power cable. It plays an important role in the development of energy internet and intelligrid. The change of temperature has a great influence on the operating state of OPLC and the accuracy of parameter measurement. It is of great practical significance to establish an OPLC thermal circuit model. In view of the wide variety and different structure of OPLC, an OPLC modeling method based on superposition principle is proposed in this paper. First, the asymmetric OPLC is modeled as several symmetric sub models, and the superposition principle is applied to superimpose each model. On this basis, particle swarm optimization algorithm is used to realize the identification of model parameters, improve the precision of parameters, get the accurate thermal circuit model, and achieve the accurate calculation of OPLC temperature at different locations. In this paper, a four cable core OPLC is taken as an example to establish the OPLC thermal circuit model. The effectiveness of the method is proved by the simulation analysis and experimental verification.
