[0002] Substations are places in power systems that transform voltage and current, receive electric energy, and distribute electric energy. They are the key to power systems. With the advancement of technology, the intelligent construction of substations and substation equipment is the development trend of power grid technology. At present, most substations are equipped with auxiliary production systems such as security defense, detection and alarm, which are mostly independent systems and cannot be controlled in an integrated and systematic manner, making it impossible for substations to meet the requirements of intelligent operation and management.
