摘要
电厂热工控制系统负责控制热工过程的温度、压力、流量、液位等参数。其安全性与稳定性直接影响热工控制系统的可靠性。电厂热工控制系统运行期间面临的干扰因素会严重威胁电厂的安全运行。阐述电厂热工控制系统差模干扰与共模干扰的表现,从信号、控制、保护误动方面分析干扰的影响,并提出抗干扰环节屏蔽干扰技术、平衡抑制技术、物理隔离技术、接地技术的应用实践,总结提升电厂热工控制系统抗干扰性能的措施,旨在通过有效的抗干扰措施提升系统的可靠性,确保电厂能够持续、稳定、安全运行。
The thermal control system of a power plant is responsible for controlling parameters such as temperature,pressure,flow rate,and liquid level in the thermal process.Its safety and stability directly affect the reliability of the thermal control system.The interference factors faced during the operation of the thermal control system in power plants can seriously threaten the safe operation of the power plant.The article elaborates on the manifestations of differential and common mode interference in the thermal control system of power plants,analyzes the impact of interference from the aspects of signal,control,and protection misoperation,and proposes the application practice of anti-interference shielding interference technology,balance suppression technology,physical isolation technology,and grounding technology.It summarizes measures to improve the anti-interference performance of the thermal control system of power plants,aiming to enhance the reliability of the system through effective anti-interference measures and ensure the continuous,stable,and safe operation of power plants.
