Large-scale generator set monitoring system

The invention relates to a large-scale generator set monitoring system which comprises a keyboard, a printer, an integrated workstation, an external communication device, an analog-to-digital conversion module, a switching volume output module, a PT/CT (Power Transformer/Current Transformer) input module, a data acquisition and signal isolation module and a warning output and monitoring software system. The monitoring system aims at the electrical quantity monitoring of a generator, has the real-time monitoring, recording and displaying functions of low-frequency oscillations and subsynchronous oscillations, and can carry out on-line identification, spectrum analysis and digital wave recording on internal parameters of the generator, capability curve displaying, real-time operating condition acquisition, computing and monitoring, P-Q graph recording and displaying, generator power angel delta and stability margin detection, operating condition simulation and predication, and the like.
