Abstract: Distribution system is the key field to build a new type of power system, and technical standards provide a unified basis for technology development and application, and are an important means to promote technological innovation and improve the technical level of the entire industry. Focusing on the requirements of the new power system, the business needs and challenges of distribution network fault handling and operation control are analyzed, and the technical standard system of distribution network fault handling and operation control is built, which can guide the scientific and technological innovation and standard precision scientific layout in related fields of distribution network, and provide strong support for the high-quality development of the new power system.
