With the development of cyber physical power system

the traditional centralized data acquisition architecture has the shortcomings of poor transparency

high data security risk

and so on

so based on the decentralization

security and credibility of blockchain

a data blockchain generation algorithm of cyber physical power system is proposed to improve the security and trusting degree in the data interaction and using process. The chain generation architecture of data block is established based on the privatization characteristic of cyber physical power system data.The chain generation rate is improved by the queuing mechanism in generating block nodes and the on-demand routing data exchange mechanism among nodes

which is combined with the characteristics of the data feature verification mechanism and the privatized blockchain to ensure the real-time transmission and storage of data. The proposed algorithm is verified by five IEEE standard examples with different scales and the simulative results show that the proposed algorithm has shorter data blockchain generation time and better transmission performance.
