Study on an expert monitoring system used for PD on-line monitoring of large turbine generators

In this paper, a newly developed generator partial discharge (PD) expert monitoring system is presented. The system consists of four major modules, including system control module, system menu module, signal processing module and result display module. The system is based on expert system technique. Operators can process PD on-line monitoring more easily and automatically. Some field PD on-line monitoring results are also given and discussed in this paper.
