The Design And Realization Of SCADA In Shenyang Power Supply Scheduling Automatic System

SCADA is a computer-based dispatch automation system for modern powersystem, which can supervise and control field equipments by acquiring data.Automation and modernization of power system dispatching can be realizedusing SCADA system, which can also improve the performing efficiency ofdispatching tremendously. Recently, Distribution Automation System (DAS) has been developed very rapidly in home and abroad, and it has been widely used in the fields of distribution system and electrical system. Among them, distribution SCADA system has been one of hot research topics in recent years. A detailed analysis on software designing of substation SCADA system has been given in this thesis.A system which is mainly made of computer and in a bid to implement ordinary four remote control functions is called Supervisory Control and Data Acquisition System (hereinafter called SCADA). Otherwise, it can also accomplish many other functions , such as data processing and management, linking to other systems, providing online training for operators, preventing error operation and auxiliary decision-making etc.In recent years, some new challenging problems have come forth in automation systems with the fast development of electric power industry. Firstly, to build transformer substation with no-operator, which often causes abnormal or even wrong data. Secondly, alarming module should be well strengthened in no-operator dispatching. Thirdly, new managing mechanism in no-operator transformer substation has brought new challenging requirements to the functions of SCADA system. With the background of the research and design of SCADA in Shenyang Power Supply dispatching center, this thesis focuses on the data acquisition and processing in that system.The practice shows that the SCADA system designed by us has a higher reliability, advanced real time and accurate data transfer. At present, the SCADA system is going smoothly, and all kinds of performance targets are also meet with Region Electricity-Net Data Precessing and Supervision Technology Requirments.
