Application of Software Testing Technology in Security and Protection of Power System

At present, the economy and society in China has developed, and infrastructure construction in China has been effectively upgraded and developed. Especially in the power industry, power and other facilities and equipment have good development prospects. Based on the background of informatization, power enterprises innovate and create themselves to meet the power demand of all users in our country. By introducing such Internet technologies as big data, power equipment can be effectively improved and upgraded. However, in the context of modern network technology, in the process of power system upgrading and transformations, attention should be paid to the protection and safety of power system to avoid security problems resulting from incompatibility between software system and power system. Therefore, this paper mainly analyzes the current status of security and protection of power system, discusses the problems of software testing system in security and protection of power system based on modern network information technology, and analyzes the application of software testing technology in security and protection of power monitoring system, so as to effectively avoid the loopholes and reduce risks in security and protection of power system.
