浅谈如何提高继电保护及安全自动装置的可靠性

摘要

Modern power system security and stability under the protection of microprocessor-based relay protection and au-tomatic safety devices reached a relatively high level.But the failure of the secondary circuit still causes device malfunction or action refusal.Therefore, as a relay maintenance personnel, we should start from the secondary circuit and take appropri-ate measures to strengthen checkup of latent danger to ensure the reliability of relay protection and automatic safety devices, so as to ensure safe and stable operation of the system.%现代电力系统的安全稳定性在微机型继电保护及安全自动装置的保障下达到了比较高的水平，主要由于二次回路的故障，仍然会造成装置误动作或拒动作。因此，作为继电保护维修人员，我们应该从二次回路入手，采取相应的措施，加强隐患排查的力度，确保继电保护及安全自动装置的可靠性，从而保证系统的安全稳定运行。
