Design of Anti-Interference of Control and Protect System of Reactor Based on FPGA

The methods of anti-interference in the design of control and protect system which based on field programmable gate array（FPGA）are introduced in this paper,based on the measures,such as the signal isolation,noise and oscillation elimination,and threshold adjustment,in the design of the hardware and the improvement of anti-interference performanceby software,to ensure the safe,reliable and stable operation of the reactors.
