提高火电厂继电保护运行可靠性的措施

Measures to Improve the Reliability of Relay Protection Operation in Thermal Power Plants

火电厂继电保护装置可以很好地保障电气设备的运行安全,当电气设备出现故障后,继电保护装置会及时将跳闸指令发给断路器,将故障元件独立出来,防止电气设备因故障造成其它设备损坏。在火电厂实际运行中,由于运行环境、人为操作不当及外界干扰等原因,会导致继电保护运行的可靠性受到影响。为了提高火电厂继电保护装置运行可靠性,从做好继电保护装置安装验收工作、继电保护装置巡检工作,加强相关人员的技术培训,加强继电保护管理等几个方面入手,做好平时检修维护工作,大大降低了火电厂继电保护拒动、误动发生率。因此,实现火电厂继电保护装置安装、运行、维护的安全及技术规范管理,能提高继电保护运行可靠性,更好地保护电气设备。

Thermal power plant relay protection device can guarantee the safety of electrical equipment operation,when the electrical equipment failure,the relay protection device will timely trip instructions to the circuit breaker,fault components will be independent,to prevent electrical equipment failure caused by other equipment damage.In the actual operation of thermal power plant,due to operating environment,improper operation and external interference,the reliability of relay protection operation will be affected.In order to improve the reliability of relay protection device in thermal power plant,starting with the installation and acceptance of the relay protection device,the patrol and inspection of the relay protection device,the technical training of the related personnel,and the strengthening of the management of the relay protection work,etc.,do a good job at ordinary maintenance work,greatly reduce the thermal power plant relay protection failure,maloperation rate.Therefore,the safety and technical standard management of installation,operation and maintenance of relay protection device in thermal power plant can improve the reliability of relay protection operation and better protect electrical equipment.
