基于调控一体化的水电站SCADA 设计与关键技术

SCADA Design and Key Technology of Hydropower Station Based on Regulation and Control Integration

主要介绍云南澜沧江流域某水电站SCADA系统设计与关键技术研究。首先,利用基于多主机、多规约、多链路的“调控一体化”技术实现电站与南网、省调、地调、上级集控中心等管控终端的数据通信及远程调控功能。其次,为满足智慧电网架构下数据实时性的要求,搭建了全厂时钟对时系统,实现控制Ⅰ区所有设备统一对时,保证数据时效性。最后,在该方案中通信网络及控制网络均采用双环双冗余网络通信方式,实现整个系统的高可靠性、高度冗余性。

This paper mainly introduces the SCADA system design and key technology research of a hydropower station in Lancangjiang Basin,Yunnan Province.Firstly,it uses the"regulation integration"technology based on multi host,multi-protocol and multi-link to realize the data communication and remote regulation functions between the power station and the South grid,provincial dispatching,local dispatching,superior centralized control center and other control terminals.Secondly,in order to meet the requirements of real-time data under the smart grid architecture,it has built the clock timing system of whole plant to realize the unified timing of all equipment in control area I and ensure the timeliness of data.Finally,in this scheme,the communication network and control network adopt network communication mode with double loop and double redundancy to realize the high reliability and high redundancy of the whole system.
