Reliability Analysis of Relay Protection and Monitoring System for Power System
With the rapid development of power market and the wide access of renewable energy,the structure and operation mode of power system have changed significantly.In order to improve the adaptability and toughness of power system,the reliability of existing relay protection and monitoring system is deeply studied,and the research methods and technical paths to adapt to new challenges are explored.The system test shows that the tension loss and performance loss of power lines have obvious changes under different temperature and humidity conditions.When the ambient temperature increases from 20℃to 40℃,the performance loss increases from 0%to 30%.However,in the extremely high humidity environment with 90%humidity,the performance loss reaches 60%.Generally speaking,the research not only effectively improves the stable operation ability of power system relay protection monitoring system in changing environment,but also improves the toughness of power system.
