主动配电网运行控制需求分析及其管理系统设计

Analysis on Demand of ADN Operation and Control and Its Management System Design

本文首先对主动配电网(ADN)的特点、控制资源和多种运行状态下的过程控制进行了分析。为了实现ADN在多种运行状态下的过程控制,设计了基于SCADA平台技术的主动配电网管理系统(ADMS)。ADMS包含全局运行决策系统、配电自动化系统、负荷主动管理系统等关键子系统。通过各子系统之间的信息交互、协同控制和统一运行管理,ADMS对并网状态下的ADN进行全局优化和区域协同运行控制,对故障状态下的ADN进行故障定位和快速恢复供电运行控制,对离网状态下的ADN进行孤网运行控制,并对ADN各种运行状态下的负荷进行主动控制和管理,满足ADN的运行需求。本文设计的ADMS在搭建的实验平台中运行可靠,为进一步研究和应用ADMS提供了参考。

Firstly, the characteristics of active distribution network（ ADN）, control resources and process control under various operat- ing conditions are analyzed in this paper. In order to implement ADN process control in a variety of operating state, an active distribu- tion network management system（ADMS） based on SCADA platform technology is designed. ADMS includes comprehensive opera- tion and decision-making system, distribution automation system, active load management system, etc. Through information ex- change, assist control and unified operation management of subsystems, the global optimization operation and regional coordinated op- eration control under grid connected status, fault location and fast recovery power supply operation control under fault status and the i- solated network operation control of ADN under off-network status can be carried out in ADMS, and the loads under various operating conditions can be actively controlled and managed to meet the ADN operational requirements. ADMS operates reliablely in the experi- ment platform, and provides the reference for further study of ADMS.
