Features: With the continuous increase in the capacity of power system transmission and distribution, 500kV and above ultra-high voltage has become the main voltage level of the transmission and distribution 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 distribution, based on the requirements of national standards, industry standards, the "Power Industry Vocational Skill Qualification Standards," and relevant transmission and distribution operation job specifications, combined with the actual conditions of 500kV ultra-high voltage transmission and distribution operation, Shanghai Ultra-High Voltage Transmission and Distribution Company has organized the writing of the "Ultra-High Voltage Transmission and Distribution Operation Skill Training Textbook" (a set of 7 volumes) to meet the training needs of ultra-high voltage transmission and distribution enterprises nationwide for team building, job training, and skill qualification assessments to adapt to the development of ultra-high voltage transmission and distribution 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, control lockout conditions, remote control process, and synchronous 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 classifications, and SQL Server 2000 and REALBASE databases;
Human-machine interface, elaborating on the functions of human-machine interfaces, taking the RD-800 system as an example, introducing general operations, human-machine interfaces, screen tools, graphic element editors, and drawing software packages;
Report generation, taking the RD-800 system as an example, introducing the startup of report software, report structures, report body creation, data description in reports, 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, discussing common faults and their solutions in 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 and reflection questions to assess learning outcomes. This book can serve as both a job skill training textbook for production personnel, technicians, and management staff in ultra-high voltage transmission and distribution enterprises nationwide for substation automation and monitoring systems, as well as an auxiliary course textbook for power vocational colleges and universities.
