发电厂继电保护的干扰因素简析

Power plant relay protection the interference factors analysis

发电厂是我国生产电能的主要基地,每年发电厂生产了大量的电能供社会各行业使用,维持了正常的社会供电状态。随着电力行业技术的改革调整,发电厂设备故障发生率逐渐上升,不仅破坏了发电厂原有的生产秩序,也导致电能产量大幅度降低。为了避免设备故障造成的不利影响,发电厂为设备配备了继电保护装置,但是发电厂继电保护常会受多项因素的干扰而导致继电保护功能受损。文章主要针对火力发电厂内的继电保护抗干扰问题进行分析。

The power plant is China＇s production of electric energy of the main base,every year power plant produces a great deal of power for social sectors use, to maintain normal social power state.As the electric power industry technical reform, Power plant equipment fault rate rises gradually, This not only destroy the power plant the original production order, also causes the electric energy production greatly reduced.In order to avoid equipment failure caused by adverse effects, power plant equipment is equipped with a relay protection device.but relay protection in power plant often by a number of factors which led to the relay protection impaired function. This paper mainly for thermal power plant of anti-jamming in the relay protection problems are analyzed.
