Abstract :
Compared with analog integrator, digital integrator is more suitable in ECT(Electronic Current Transducer) based on Rogowski coil for its advantage of agility and good consistency. In this paper several digital integration algorithms were compared through simulation. According to the requirement of accuracy and conditions for hardware implementation, Romberg integration algorithm achieved in FPGA using three pipeline structure was chosen. The experiment result verified the validity and practicability of the design.
