Abstract

The invention discloses a generator terminal abnormity monitoring system and method, electronic equipment and a computer readable storage medium. The system comprises: at least one group of voltage transformers, wherein each group of voltage transformers comprises three voltage transformers which are used for converting a primary voltage outputted by a generator terminal, so as to obtain a three-phase secondary voltage, and transmitting the three-phase secondary voltage to the computer readable storage medium, and the secondary voltages of the three phases are synthesized to obtain an open triangular voltage corresponding to the group of voltage transformers; and a monitoring device connected with the open-delta voltage corresponding to the at least one group of voltage transformers so as to monitor the abnormality of the generator terminal according to the correspondingly connected open-delta voltage. According to the invention, the effectiveness of generator terminal abnormity monitoring can be improved.

Description

technical field [0001] The present application relates to the technical field of generator safety, and in particular to a generator end abnormality monitoring system, method, electronic equipment, and computer-readable storage medium. Background technique [0002] At present, for generator protection systems, generator excitation systems, and electrical measurement systems, etc., it is generally determined whether there is a generator terminal by monitoring the secondary disconnection of the potential transformer (PT) that provides the secondary voltage for the above systems. abnormal. However, for the special phenomenon of "slow melting" of the PT high-voltage side fuse at the generator end, effective monitoring methods cannot be realized. However, once the "slow melting" of the PT high-voltage side fuse at the generator end occurs, it will cause abnormal actions such as false magnetization of the automatic voltage regulator (AVR), abnormal electrical protection, and inacc...
