Abstract: Electromagnetic compatibility (EMC) of electronic control system means the electronic system still has the normal working ability in the electromagnetic environment, and will not become a source of electromagnetic pollution in the environment. Generally use the "immunity" to measure anti-interference ability of the electronic control system in the electromagnetic environment; use the "emission" to show its electromagnetic pollution for the environment. A control system in industrial process is facing all kinds of electromagnetic interference (EMI), we cannot and should not the anti-interference function entirely by the control system of itself to undertake, it must to in the engineering implementation is taken various measures to ensure the normal operation of the control system in the industrial environment. This paper reviews several issues related to electromagnetic compatibility in the design of control room: 1) Technical specification for equipment selection ; 2) Voltage between neutral and ground for AC low voltage power supply system; 3) Electrostatic protection in control room; 4) Electromagnetic compatibility of lighting lamps; 5) Electromagnetic compatibility of the relay in the cabinet; 6) Electromagnetic compatibility of cable system in control room.
