摘　　要：为解决现有采样共享方式存在的局限性,提出了多频采样、定周期采样和有效值输出等多种采样共享方式。研制了新型合并单元样机,验证了采样共享方案的可行性。提出的采样共享方案有利于变电站二次设备的进一步集成,有利于解决电力物联网建设中基础数据的共享问题。Sampling sharing modes such as multi-frequency sampling,periodic sampling and effective value output were proposed in order to overcome limitations of existing modes.A novel prototype of merging units was developed,and the feasibility of the sampling sharing scheme was verified.The proposed sampling sharing scheme was conducive to further integration of the secondary equipment of the substation and to the solution of sharing of basic data in the construction of the Power Internet of Things.
