| Abstract: | A simulation training system for distribution network relay protection is developed. The system consists of physical simulation platform and software simulation platform for distribution network protection. The physical simulation platform of distribution network protection is designed and realized on the basis of the equivalent principle of identical impedance monoids, which has the functions of training operation, fault simulation, protection verification and so on. The software simulation platform of the distribution network relay protection realizes the functions of distribution network relay protection configuration and setting, theoretical training and examination based on graphical interface. PSCAD/EMTDC software is used to build a simulation model which is consistent with the physical simulation platform. The results of the three platforms are compared from the following three aspects: simulation waveform, short circuit current and protection action. The validation shows that the developed system can simulate the faults of distribution network and verify the configuration and setting of protection. It is an efficient experimental training platform to improve the learning and training effect of relay protection in distribution network. |
