Dispatching automation system referred to as SCADA (Supervisor Control And Data Acquisition) systems , monitoring and control and data acquisition system . Power Dispatching Automation System is to ensure grid security , stability, and an important means of economic operation , the operational status of the power system and monitor the operation of the means for the entire electric power automation systems , its role has become increasingly receive attention , a grid scheduling indispensable effective tool . This paper introduces a new scheduling automation system based on Windows NT hardware structure , software architecture , the main function , performance and technical characteristics . Basic process flow of the SCADA system , the organizational structure of the program system module division , function allocation , interface design , operational design , data structure design and safety design is analyzed in detail . The scheduling automation system using the Windows NT operating system , a distributed architecture with C / S , B / S hybrid structure mode combining its design ideas , software development tools for object-oriented programming methods and more popular application of real - time database technology , scripting technology , binary -level code reusable component technology , the dual-network dual system redundant fault-tolerant technology , so that the system has higher reliability , flexibility , and better versatility , practicality and scalability .
