IEC 60045-1:2020

Overview

IEC 60045-1:2020 is the international standard specifying technical requirements for land-based horizontal steam turbines primarily used for driving generators in electrical power services. This standard, issued by the International Electrotechnical Commission (IEC), serves as a comprehensive guideline to inform purchasers about relevant options and alternatives, enabling clear communication of technical requirements to suppliers.

As a second edition replacing the 1991 version, IEC 60045-1:2020 incorporates technical revisions reflecting the latest advancements in steam turbine technology and operational safety, including updated clauses on product safety and automation. The scope also covers connections with related auxiliaries such as generators and gearboxes, though detailed specifications of these auxiliaries are not included.

Key Topics

IEC 60045-1:2020 provides essential guidelines across various areas critical to steam turbine operation and procurement:

• Scope and Application
  Clear boundaries for applicability, with an emphasis on turbines for power generation and references to turbines for other applications.

• Terms and Definitions
  Precise definitions for turbine types, steam admission methods, operational speeds, steam flow rates, heat rates, and operational regimes to standardize terminology.

• Performance Guarantees
  Specifications surrounding thermal performance, including turbine efficiency, output, steam flow capacity, and permissible tolerances.

• Product Safety
  Integration of risk assessment and risk reduction processes specifically tailored to steam turbines, including hazard identification and safety documentation.

• Operation and Maintenance
  Guidelines on normal and abnormal operation procedures, installation conditions (indoor/outdoor, seismic considerations), and maintenance requirements to ensure reliability and longevity.

• Component Specifications
  Detailed considerations on materials, design, stressed and unstressed parts, rotor balancing, overspeed protection, valve functions, bearings, thermal insulation, and welding.

• Exhausts and Steam Extraction
  Design and operational parameters for steam outlets, extraction lines, protection devices to prevent backflow, and boundary conditions for performance guarantees.

• Auxiliary Systems
  Lubricating oil systems, control fluids, sealing mechanisms, drains, vents, turning gears, and piping specifications critical to turbine auxiliary operations.

• Automation and Control
  Updated clauses on integration of automation, including environmental requirements, electromagnetic compatibility, hardware and software design, control system functions, speed and load adjustments, and valve testing.

Applications

IEC 60045-1:2020 is essential for a broad range of stakeholders involved in steam turbine procurement, installation, and operation, including:

• Power Generation Companies
  Ensuring turbines meet required electrical power output, efficiency, and operational safety standards.
