摘要/Abstract

摘要： 目前智能变电站广泛采用“智能终端+合并单元”过程层设备，但该方式合并单元无法满足“装置内部单一元件的损坏不能造成保护误动作”的基本要求。同时过程层设备间报文大多为一帧模式，一旦报文出现异常往往会导致保护误动。为提高继电保护的可靠性，提出了采集和控制完全双重化的新一代装置架构，探讨电压无缝选择技术、延时可测交换技术、过程层组网、插值算法等关键技术。新一代采控装置大幅提高了智能变电站的可靠性。

关键词: 智能变电站, 高可靠性, 采控装置, 延时可测

Abstract: At present, smart substations adopt process-level equipment of "intelligent terminals and merging units". In this way, the merging unit cannot meet the basic requirement of "the damage of a single component inside the device cannot cause the protection to malfunction". In the process layer, messages between equipment are mostly in one-frame mode. Once the message is abnormal, it will often cause the protection to malfunction. In order to improve the reliability of relay protection, a new generation device architecture with complete dual is proposed. Key technologies such as voltage seamless selection technology, time-delay measurable switching technology, process layer networking and Lagrange interpolation are proposed.

Key words: smart substation, high reliability, control device, delay measurable
