摘要:In order to accomplish parameters estimation and prediction of zero
crossing point, and determine fault types quickly and accurately, we
designed a three-phase controlled fault interruption control system. The
hardware of control system has the field-programmable gate array
EP4CE15F17C8N as the controlling core with AD sampling, bus transaction
and other peripheral circuits. Based on the principle of controlled
fault interruption and adaptive RLS algorithm, the fault initial time
detection and waveform recovery were completed, and the software of
control system was designed. Moreover, through experimental circuit
built by the relay protection tester, we tested the accuracy and
stability of the system. The results show that the system can determine
the occurrence of fault within 3 ms, and the result of 3sigma of zero
crossing point errors is [-0.240 2, 0.416 2] ms. This means that the
control system meets the demands of the accuracy and speed of controlled
fault interruption.
