基于IEC 61970标准的多控制中心间无功电压协调控制信息交互模型设计

Design of IEC 61970 Based Information Exchange Model for Coordinated Automatic Voltage Control Among Multi Control Centers

标准化是未来控制中心信息交互的发展方向。基于IEC 61970标准,提出一种适用于多控制中心间无功电压协调控制(coordinated automatic voltage control,CAVC)的信息交互模型。首先分析CAVC信息流内容,给出用于信息交互的协调控制模型定义;对公用信息模型进行扩展,设计出CAVC标准化信息模型;基于组件接口规范,设计CAVC标准化信息交互接口,并给出其信息交互框架和信息交互数据流程;该信息交互模型在实现智能电网条件下CAVC的多控制中心间信息交互方面具有广阔的应用前景。

Standardization is the development tendency of information exchange among control centers. Based on the standard in IEC 61970, an information exchange model suitable for coordinated automatic voltage control （CAVC） among multi control centers is proposed. Firstly, the contents of information flow of CAVC is analyzed and the definition of coordinated control model for information exchange is given; then the common information model is extended and a standardized information model for CAVC is designed; and then based on component interface specification, a standardized information exchange interface for CAVC is designed and its architecture for information exchange as well as its information exchange procedure are given. The presented information exchange model possesses wide application prospect in the implementation of information exchange among multi CAVC control centers for future smart grids.
