摘　　要：针对电网发生扰动或故障等非稳定运行时易造成机组轻微过度调节的问题。根据相关设备的实际安装情况,通过比较变送器模拟量输出与机端直采值,指出传统的电磁式功率变送器因暂态稳定性差、响应时间长、抗干扰能力弱等不足导致输出失真的问题。同时,提出对应的解决措施,对于提高机组安全性和可靠性意义重大。In order to solve the problem that unstable operation such as disturbances or fault in the power grid is easily cause slight over-adjustment of the unit.According to the actual installation situation of the relevant equipment,by comparing the analog output of the transmitter with the direct acquisition value at the machine end,it is pointed out that traditional electromagnetic power transmitter has the output distortion problems caused by poor transient stability,long response time,and weak anti-interference ability.At the same time,corresponding solutions are proposed,which are of great significance for improving the safety and reliability of the unit.
