摘要
为切实提升电厂运行效益,提升电厂继电保护装置安全运行可靠性,需加强电厂继电保护装置检修与管理工作。该文首先分析电厂继电保护装置的特点,对电厂继电保护装置常见二次回路故障、继电器接触错误、通信信息错误、样本值无效、A/D通道采样值不匹配及接收采样值消息时间间隔差异大等问题进行详细论述,并据此提出针对性管理策略,希望能为相关人员提供借鉴与指导。
In order to effectively improve the operation efficiency of the power plant and improve the safety operation reliability of the relay protection devices in the power plant, it is necessary to strengthen the maintenance and management of the relay protection devices in the power plant. First of all, this paper analyzes the characteristics of relay protection devices in power plants, and discusses in detail the common secondary circuit faults, relay contact errors, communication information errors, invalid sample values, mismatch of sampling values in A/D channel and large time interval difference in receiving sampling value messages, etc. Based on this, the paper puts forward targeted management strategies, hoping to provide reference and guidance for relevant personnel.
