摘要(Abstract):
围绕以新能源为主体的低压配电物联网的核心业务应用——台区拓扑自动识别,提出了一种综合考虑识别可靠性、识别准确率与识别抗扰能力的拓扑自动识别技术测试方案,并研制专用的配电物联网台区“边-端”交互试验平台。对浙江省电力有限公司主流技术方案的功能和性能进行了全方位测评,选取“有功电流注入+频域信号检测”作为最优拓扑识别技术方案。台区拓扑识别技术测试研究可为后续实现配电物联网互联、互通、互操作建设,推动配电网数字化的转型发展奠定应用基础。
This paper centers on the core business application—the automatic topology identification in transformer areas—of distribution IoT with new energy as its mainstay. It proposes an automatic topology identification technology testing scheme that considers identification reliability, high identification accuracy, and anti-disturbance capability. Besides, a unique “edge-to-end” interaction test platform for the distribution IoT area is developed. Afterward, the functions and performance of the mainstream technical schemes of Zhejiang Electric Power Co., Ltd. are evaluated in all aspects. The “active current injection plus frequency-domain signal detection” is selected as the optimal technical scheme for topology identification. The topology identification technology testing and research can lay the application foundation for the subsequent interconnection, intercommunication, and interoperability of the distribution IoT and the transformation of the distribution networks.
