Abstract: Distributed photovoltaic generation is valued because it's environmentally friendly, geographical limitation is small, and investment is little in our countary's new energy development.But the operation datas of the distributed photovoltaic generation distribut in their own different system.So it's dificult for the dispatching operator to do with these different datas source.Useing the voice techonlogy to realize the speech-recognition, speech analysis, data searching and date output, the data acquistion become more efficient. Through multiple presentations provid all round data supply for the power grid operation caculation.
