Abstract: Considering problems of the incomplete protection and control strategy for the distribution network and the lack of a control model for the multimodal application, we proposed an intelligent distribution network protection and control strategy using a modulus matrix, studied the control strategy and model under multimodal application, and explored the protection architecture design under "permissive", "locking" and "tripping" control strategies.Through experiments, it is proved that the proposed distribution network protection and control strategy can work together with the traditional protection strategy module, and it is easy to realize the integrated design of the distribution network terminal hot plug function module, which is of great significance to the upgrading of the distribution network protection architecture.
