| The wind-photovoltaic-diesel power system were more and more be used at today that the tension in energy. It has a higher requirement about the efficiency, stable and safe operation of the wind-photovoltaic-diesel power system.Besides for the system design,system and optimizing the real-time monitoring of energy will be scheduling system more efficient and reliable operation. So for scenery of the monitoring system of wind-photovoltaic-diesel power system research has important significance.This article is based on the background.First, analyses the nervous energy in today,it is indicated the necessity to develop solar and wind power generation, and indicated solar-wind power application status and research at current domestic and international.It were analyzed and studied.the existing distributed generation monitoring system.Given the overall design scheme of the monitoring system which made by VB and the Microcontroller of dsPIC30F3011.Secondly, it were detailed introduces the hardware composition and software realization method the data collection interface circuit,keyboard,LCD display interface circuit,communication interface circuit of the the control system which made by dsPIC30F3011.It was realized the data communication between superordination machine by RS485-232 bus.Then By using Visual Basic6.0 visualization editor developed PC human-machine interface,achieve the real-time data refresh,storage,printing the selection of serial setting function.Finally, I design the PCB board of the data acquisition card.We do the experiment combined with the PC,the experimental results of the system show that the system design is reasonable.
