The research and development of supervision system for wind/photovoltaic hybrid grid-connected generation

This paper introduces an system of collecting the data of wind-solar hybrid generation with the core of AT89C55WD. The aspect of hardware introduces sensors particularly producing several kinds of input signals, including analyzing the circuit of hardware according to the input signal; The aspect of software introduces SCM controlling system and acquisition flow. The SCM communicates with computer by the module of GSM. Data manage system is built up by Visual Basic combined with the database of ACCESS.
