电厂继电保护二次回路的调试技术探讨

Discussion on the Adjustment Technology of the Secondary Circuit of Power Plant Relay Protection

在电厂运行中,继电保护系统起着保护作用和监督作用,在对二次设备和二次回路运行进行监督的过程中,自动调控断路器,使其能在设备故障时及时启动,发挥预警保护作用。继电保护系统越完善、高效,电力系统运行越稳定。因此电厂比较看重继电保护维护工作。在维护中,维护人员还要做好继电保护和二次回路的调试工作,使其处于正常运行状态,消除偏差。该过程涉及到调试技术,维护人员还需按照调试步骤落实技术。

In the operation of power plant, relay protection system plays a protective and supervisory role. In the process of supervising the operation of secondary equipment and secondary circuit, it will automatically regulate the circuit breaker, so that it can start in time when the equipment fails and play the role of early warning and protection. The more perfect and efficient the relay protection system is, the more stable the power system will be. So the power plant pays more attention to the maintenance of relay protection. In maintenance, maintenance personnel should also do a good job in relay protection and secondary circuit debugging, so that it is in normal operation and eliminate deviations. This process involves debugging technology. Maintenance personnel also need to implement the technology according to the debugging steps.
