Abstract
With the continuous development and scale expansion of the power system, its complexity and operating pressure increase significantly. As an important guarantee for the safe and stable operation of the power system, the reliability and accuracy of the relay protection are directly related to the security and stability of the whole power grid. This paper gives a comprehensive overview of the basic concepts, main types of relay protection, the possible causes and corresponding countermeasures in the actual operation. Firstly, starting from the definition, function and characteristics of the relay protection, the basic principle of protecting the safe and stable operation of the power system is analyzed. Subsequently, four main types of relay protection, including current protection, voltage protection, distance protection and differential protection, are introduced in detail, each of which provides effective protection strategies for specific fault situations. Analyze the main causes of relay protection failure in power system, including equipment factors, operation problems and environmental factors. The existence of these factors poses a serious threat to the reliability and stability of the relay protection system. In view of the above failure reasons, this paper puts forward the corresponding countermeasures. From strengthening equipment quality management, optimizing operation management, improving environmental conditions and improving personnel quality and management level, a series of concrete and feasible solutions are put forward. These measures are designed to improve the overall performance of the relay protection system, reduce the possibility of failure, and can quickly and accurately locate and solve problems in the event of failure, so as to ensure the safe and stable operation of the power system.
