摘要(Abstract)：
随着能源互联网的建设和电力物联网技术的成熟,配电网台区终端类产品广泛应用于电力系统配电网台区中,在现有配电物联网架构下,大量台区终端的接入会带来过于中心化、数据安全等问题。首先,针对这些问题提出基于区块链技术的配电网分布式台区终端系统,对系统整体架构进行说明,分析了采用分布式终端系统的必要性。然后,提出基于可信芯片的随机数证明共识机制,并从区块传播时间、吞吐量和CPU占用率三方面论证了机制的优越性。最后,对系统的优势进行讨论,同时对区块链技术和电力物联技术的融合进行了展望。
With the construction of the energy internet and the maturity of the power IoT(Internet of Things)technology, terminal products for power supply area of distribution networks are of wide application. However,the terminal systems applied in the present power IoT architecture of distribution networks in massive scale may bring about overcentralization and data security concerns. In view of the problems, the paper firstly proposes a terminal system for power supply area of distribution networks based on blockchain technology, illustrates the overall architecture of the system and analyzes the necessity of the distributed terminal system; then it proposes a proof of random number consensus mechanism based on trusted chips, and discusses the superiority of the mechanism concerning block propagation time, throughput and CPU usage; finally, it discusses the advantages of the system and looks ahead to technological convergence of blockchain and power IoT.
