[Abstract]At this stage, my countrys society and economy continue to develop and progress. In the process of production and life, the demand for electricity is gradually increasing to meet the needs of social production and life. The demand for the power system in actual use continues to increase, and active and effective maintenance has not been taken. Under the premise of the plan, potential safety hazards in the use of the system will be increased, the economic benefits of thermal power plants will also be affected, and the workload of maintenance staff will increase. Based on this situation, the relay protection system was born. The use of this system can protect the power supply, improve safety, and play an important role in the production and progress of thermal power plants. The detection and maintenance measures of relay protection in thermal power plants are analyzed, combined with the current status of use, specific solutions are proposed to promote the improvement of the quality of relay protection in thermal power plants.

电力系统实际运行中,经常会出现一部分情况,例如电气设备绝缘损坏以及操作弊端等外部因素影响,出现短路事故以及运行状态不正常情况。运行过程中产生的严重事故主要有停电、系统解列、区域大面积停电等。在电力系统发生一定事故时,需要在最短时间内采取积极有效的措施,及时排除故障,防止出现更加严重的后果。电力系统产生异常运行状态,继电保护装置系统的应用可以在最短时间内发出预警信号,工作人员及时处理,事故出现时,继电保护装置可以自动切除故障,缩小事故出现范围。
1 继电保护系统概述
伴随经济不断发展,用电需求逐渐增加,火力发电厂的生产规模也在增加,基于这一情况,使用大容量的发电机组是生产过程中的重要内容,也是电厂生产的核心设备,在发电机组出现故障情况下,会对火力发电厂造成十分严重的经济损失。……
