摘要
在实际运行过程当中,热工控制系统时常会受到一定的信号干扰,对其造成十分不良的影响。在信号干扰之下,电厂热工控制系统将会出现控制失灵、测量偏差等故障,甚至会引发电力安全事故。因此,对于电厂热工控制系统中干扰信号的来源要进行详细的分析,同时采取科学、有效的控制对策,对干扰进行控制,从而充分保障电厂热工系统的安全运行。
In the actual operation of the process, the thermal control system is often subject to a certain signal interference, which has a very bad effect. Under the interference of the signal, the power plant thermal control system will appear the failure of control, measurement error, and even lead to power safety incidents. Therefore, for thermal power plant control system interference signal source to carry out detailed analysis, at the same time, take scientific and effective control measures of controlling interference, in order to fully protect the safe operation of the thermal system of power plant.
