Abstract

The invention provides a differential protection method and system for a distributed wireless communication power distribution network, and the method comprises the steps: enabling a safety TF card to be installed in a CPE terminal, encrypting the data of a differential protection device through the safety TF card, and transmitting the encrypted data to another CPE terminal through a safety access gateway, thereby achieving the safety transmission of the data of the differential protection device, and ensuring the safety of the differential protection method. Moreover, the security TF card encrypts the data of the differential protection device, the security access gateway forwards the encrypted data to the CPE terminal, and the security access gateway does not need to encrypt and decrypt the data in the whole process, so that the time delay loss of data transmission is reduced, and the differential protection efficiency is improved.

Description

Technical field [0001] The present application relates to the field of communication technology, and in particular, to a differential protection method and system of distributed wireless communication distribution network. Background technique [0002] With the access to a large number of distributed power supplies, higher requirements have been made on the fault handling capacity of the distribution network. Traditional distribution network fault treatment utilizes a differential protection scheme based on fiber optic low-time delay, but is laid in the city to lay fiber costs and distribution points in fiber. [0003] With the maturity of wireless communication technology, its low delay, high bandwidth and no need to lay fiber provide possible to solve the above problems. [0004] However, the safety of the distribution network of wireless communication technology is currently low. Inventive content [0005] In order to solve the above technical problem, the present application...
