Features: With the continuous increase in the capacity of power transmission and transformation, 500kV and above ultra-high voltage has become the main voltage level of the transmission and transformation network. To meet the strategic decisions of nationwide interconnection and west-to-east power transmission, as well as the construction and operation of ultra-high voltage AC and DC transmission and transformation, based on the requirements of national standards, industry standards, and the "Power Industry Vocational Skill Qualification Specification," as well as relevant transmission and transformation operation post specifications, combined with the actual conditions of 500kV ultra-high voltage transmission and transformation operation, Shanghai Ultra-High Voltage Transmission and Transformation Company organized the writing of the "Ultra-High Voltage Transmission and Transformation Operation Skill Training Textbook" (a set of 7 volumes) to meet the training needs of ultra-high voltage transmission and transformation enterprises nationwide for team building, post training, and skill qualification assessments to adapt to the development of ultra-high voltage transmission and transformation networks. "Substation Automation and Monitoring" is the third volume of this textbook, divided into 8 chapters, with the main content including:
I/O measurement and control unit data acquisition, introducing the principles of DC analog quantity acquisition, AC analog quantity acquisition, digital quantity acquisition, and I/O measurement and control unit acquisition principles;
I/O measurement and control unit control functions, introducing remote control and remote control output requirements, control output interfaces, local and remote control forms and types, lockout conditions for control, remote control process, and synchronization control functions and their implementation processes;
Network fieldbus and network interfaces, introducing the concept and types of networks, as well as conventional network protocols and network physical layers, with a detailed introduction and comparison of several network connection methods for substation automation and monitoring systems in Shanghai Power Grid;
Database, introducing the composition of databases, concepts such as data warehouses, and providing an overview of database management systems, database classification, and SQL Server 2000 and REAL-BASE databases;
Human-machine interface, elaborating on the functions of human-machine interfaces, taking the RD-800 system as an example, introducing general operations of the RD-800 system, human-machine interface, screen tools, graphic element editor, and drawing software packages;
Report generation, taking the RD-800 system as an example, introducing the startup of report software, report structure, report body creation, report data description, report title creation, and other aspects;
Acceptance testing, explaining the content, requirements, and methods of acceptance testing, with detailed descriptions of acceptance and testing methods for some specific projects;
Common fault diagnosis and handling, elaborating on common faults and handling methods of substation automation and monitoring systems, covering interval layer RTUs, I/O unit sections, substation layer backend monitoring sections, and database backup sections.
Each chapter includes review questions to assess learning outcomes. This textbook can serve as both a job skill training manual for production personnel, technical staff, and management personnel in ultra-high voltage transmission and transformation enterprises nationwide for new, on-the-job, transferred, and re-entering positions, as well as an auxiliary course textbook for power vocational colleges and higher vocational colleges.
