Features: As the transmission and distribution capacity of power systems continues to grow, ultra-high voltage (UHV) of 500kV and above has become the primary voltage level in transmission and distribution networks. To meet the strategic decisions of nationwide power grid integration and west-to-east power transmission, as well as the construction and operation of UHV AC and DC transmission lines, this training textbook on UHV Transmission and Distribution Operation Skills (a set of 7 volumes) was compiled by Shanghai Ultra-High Voltage Transmission and Distribution Company. Based on years of experience in UHV transmission and distribution operation and training, and in accordance with national standards, industry standards, the "Power Industry Vocational Skill Qualification Standards," and relevant operation specifications for transmission and distribution positions, the textbook aims to meet the training needs of UHV transmission and distribution enterprises across the country for team building, job training, and skill assessment to adapt to the development of UHV transmission networks.
"Transmission and Distribution Operation" is the volume of this set, divided into 4 parts and 22 chapters, covering the following main content:
Part 1: Power System and Substation
Introduces concepts of power systems and neutral points, substation operation dispatch management, main circuit connections and anti-misoperation, switching operations and operation tickets, substation equipment inspection and maintenance, substation work permits and approval and acceptance.
Part 2: Main Electrical Equipment and AC/DC Auxiliary Systems
Introduces the structural connections, performance parameters, operating mechanisms, operation and maintenance, and fault handling of transformers, circuit breakers, disconnectors, current and voltage transformers, capacitors, reactors, arc suppression coils, lightning arresters (grounding rods), busbars, insulators, and power cables. Additionally, it covers the composition, operation, and fault handling of AC/DC auxiliary systems.
Part 3: Relay Protection
Introduces the protection configurations, circuit designs, and operation of 220kV busbars, circuit breaker failure protection, transmission lines, and main transformers. It also covers backup power automatic switching devices, cooling power automatic switching devices, control circuits, busbar differential protection configurations, structural principles, action analysis, operation, and abnormal handling. Furthermore, it includes the screen layout, logical structure, short-circuit protection, operation, action analysis, and abnormal handling of 500kV line PLS high-frequency protection, TLS distance protection, circuit breaker failure protection, and reclosing. Additionally, it covers the configuration, structural principles, overvoltage protection, remote tripping, short-circuit protection, operation, action analysis, and abnormal handling of 500kV line ASEA protection, SEL main protection, and REL differential, distance, zero-sequence overcurrent protection, circuit breaker failure protection, and reclosing. Lastly, it covers the configuration, functional principles, AC/DC power sources, operation, and abnormal handling of ABB protection for 500kV main transformers.
Part 4: Substation Operation Management
Introduces substation on-duty and handover procedures, spare parts and materials, operation analysis, seasonal considerations, training and education, project construction and renovation, equipment defects and grading, regular equipment switching and operation, equipment nameplates and spare storage, reactive power and insulation supervision, AC/DC power sources, automation equipment, technical documents, operation and work permits, regulation drafting and review, safety inspections, prevention of full-substation outages, hazard analysis, anti-misoperation, safety tools, prevention of small animal faults, fire safety and security management.
Additionally, each chapter includes review questions, and at the end, there are the main transformer inspection operation guide, sample relay protection approval and acceptance card, and typical circuit breaker introductions.
