自主可控新一代变电站辅助系统联控策略研究与发展

为了从根本上解决电网二次设备核心芯片“卡脖子”问题,全面支撑变电站“无人值守+集中监控”业务需求,新一代自主可控变电站采用“自主可控、安全可靠、先进适用、集约高效”的原则,从设备软硬件方面全面自主设计可控。为更好建立新一代自主可控变电站,研究分析了二次系统的联动控制策略。首先,从联动控制所需基础技术分析,介绍自主可控新一代变电站辅助设备联控策略的总体框架,分析变电站辅助设备联动控制的总体功能;然后,通过梳理辅助设备联控类型,将联控策略分为主辅联动、子系统间联动和子系统内部联动三大策略,并结合具体案例对联动控制进行阐述;最后,对变电站辅助设备联动控制策略进行总结和展望。

Research and Development of Auxiliary System Joint Control Strategy in New Generation Substation with Autonomous and Controllable Technology

In order to fundamentally solve the problem of "stuck neck" in core chip of secondary equipment in power grid and fully support the business needs of "unattended and centralized monitoring" of substations, a new generation substation with autonomous and controllable technology adopts the principles of "autonomous and controllable, safe and reliable, advanced and applicable, intensive and efficient", and is designed and controlled independently in terms of equipment hardware and software. In order to have a better construction to new generation substations with autonomous and controllable technology, it focuses on the analysis of joint control strategy of secondary system. Firstly, the basic technologies needed by joint control are analyzed. The overall framework of joint control for auxiliary equipment of new generation substations with autonomous and controllable technology is introduced, and its overall functions are analyzed. And then by sorting out the types of auxiliary equipment joint control, the joint control strategies are divided into main and auxiliary linkage, inter subsystem linkage and intra subsystem linkage, and the joint control is described with specific cases. Finally, the joint control strategies of auxiliary equipment in substations are summarized and prospected.
