摘要
分析了风电场电磁环境对风机主控PLC产生的影响和潜在危害。通过对电磁干扰的来源及产生机理的分析,设计了一种PLC的供电电源,此电源能在强电磁干扰环境下保证PLC正常工作,满足PLC供电要求。
The influence of the electromagnetic environment of the fan wind farm on master PLC （programmable logic controller） was analyzed. The origin and mechanism of electromagnetic interference was studied, and a power supply for PLC was designed, which can work normally in strong electromagnetic interference environment to meet the power requirements of PLC.
