In this paper, the main interference sources of quasi-synchronizing device and their effects to the system are introduced and a set of all-sided solution for enhancing anti-jamming capability of the device, which contains the anti-jamming measures with the hardware and software respectively and the protective measures of the system, is put forward. At present, the anti-interference and protection measures have already been applied to the practical microcomputer-based quasi-synchronizing device, and furthermore have passed the related anti-interference experiment. These have a certain effect for further improving anti-jamming capability of microcomputer-based quasi-synchronizing device and insuring the safe and stable operation of electric power system. Moreover, the paper also provides some references for the designer of the quasi-synchronizing device.
