Abstract:In order to solve the data acquisition problems caused by the increase of the distributed resources penetration on the grid and development of the ubiquitous power internet of things，accurately grasp the operation of distributed power sources within the state-grid company，aim at the future development trend of the power system, improve the ability of power grid to accept new energy and promote the coordinated development of energy consumption for the electricity market，this paper uses VC++ technology, combined with the functions of D5000 system,The management system D5000 has the functions of logical calculation and alarm, and has developed the function module of new energy monitoring to provide monitoring and economic dispatch of new energy.To solve the problem of the frequent occurrence of grounding faults in distribution network, the development function of D50000 system is adopted, and the automatic alarm function is reasonably set up to promote the security and stability of power grid.Based on the big data analysis, the software was developed independently To solve the problem of low accuracy of grounding pull in distribution network.The simulation results show that the platform improves the economic and safety of the distribution network operation, and promotes the effectiveness of photovoltaic poverty alleviation.
