ABSTRACT

The increasing penetration of new energy into the power system is accompanied by a series of challenges that traditional relay protection systems face: fast fault detection and decreased protection action time, and decreased system stability. By taking a series of countermeasures, the paper explored the influence of new energy connection on traditional relay protection systems in response to the occurrence of the above phenomenon. These countermeasures include protection logic and settings optimization, fast fault detection technology application, adaptive protection strategy application, and enhancing communication and data processing systems. After the countermeasures were applied, the response time was improved, that is, the speed of fault detection and protection action was improved. The stability of the systems was optimized through implementing protection strategies, enhancing the dynamic response capability, and applying data analysis and intelligent technology. As new energy has impacts on the traditional relay protection system, through applying a series of countermeasures, the fault detection and protection action speed was waned, and the stability of the system was increased.
