Guide for procurement of power station equipment - Part 2-6: Electrical equipment - Generators

This standard gives guidance on writing the technical specification for the procurement of turbine-driven generators and their auxiliaries for use in electricity generating stations (power stations). This Guide for procurement is not applicable to equipment for use in the nuclear reactor plant area of nuclear power stations. Other possible applications of such equipment have not been considered in the preparation of this Guide. The generators may be air, hydrogen, or liquid-cooled. The excitation system may be of the static or rotating rectifier type fed by a static or rotating power supply. The equipment covered by this Guide is defined by its function rather than design type. Therefore, the guidance to the specification is stated in performance terms rather than being specified by a detailed description of the equipment to be supplied. This Guide indicates to potential purchasers how their specification should be prepared so that: - the equipment type and capacity interfaces correctly with other elements of the systems; - predicted performance is achieved; - ancillary equipment is properly sized; - reliability, availability and safety requirements are achieved; - proper consideration is given to the evaluation process and the quality measures to be applied. This Guide does not determine the type of specification (e.g. detailed, performance, functional) or the extent of supply for any given contract which is normally decided on the basis of the purchaser’s project strategy. It does not cover: - any commercial, contractual or legal issues which are normally in separate parts of an enquiry; - any allocation of responsibilities which are determined by the contract. This Guide does not prescribe the arrangement of the documents in the enquiry. NOTE: As a comprehensive European environmental policy is still under preparation, this Guide does not address the environmental implications of the equipment.

Overview

EN 45510-2-6:2000 is a European standard published by the CLC that provides comprehensive guidance for the procurement of electrical generators used in power stations. Specifically, this part-Part 2-6-focuses on turbine-driven generators and their auxiliary equipment in electricity generating stations (power stations). The standard aims to assist purchasers in preparing precise and effective technical specifications for generators, ensuring optimal integration, performance, and reliability.

This guide applies to various types of generators, including air-cooled, hydrogen-cooled, and liquid-cooled models, as well as excitation systems of static or rotating rectifier types. It emphasizes defining equipment by function and performance criteria rather than detailed design specifics, enabling a flexible and performance-driven procurement process.

Key Topics

• Technical Specification Guidance
  The standard directs how to write performance-based specifications for turbine-driven generators. It highlights the importance of clear definition related to capacity, interfaces, and integration with power station systems without dictating exact design models.

• Equipment Types Covered

  • Air-cooled generators
  • Hydrogen-cooled generators
  • Liquid-cooled generators
  • Excitation systems (static or rotating rectifier-fed)

• Performance and Reliability Parameters
  Ensures that the technical requirements deliver the predicted generator performance, reliability, availability, and safety aligned with operational demands.

• Auxiliary Equipment Sizing
  Provides criteria to correctly size ancillary equipment essential for generator operation and support.

• Specification Preparation
  Explains how to consider evaluation processes and quality control measures vital to the procurement and installation phases.

• Exclusions

  • Not applicable for generators within nuclear reactor plant areas
  • Does not cover commercial, contractual, or legal procurement issues
  • Does not specify environmental considerations, aligned with pending European environmental policies

Applications

This standard is essential for:

• Power Plant Engineers and Procurement Specialists
  Assisting stakeholders involved in acquiring turbine-driven generators with a structured approach to drafting technical requests, ensuring compatibility with existing systems and meeting performance targets.

• Manufacturer and Supplier Communications
  Defining clear expectations and performance targets that manufacturers must meet, thus streamlining supplier evaluation and selection.

• Power Generation Equipment Specification
  Supporting the creation of performance-oriented, functional specifications rather than prescriptive designs, promoting innovation and adaptability.

• Reliability and Safety Assurance
  Integrating safety and reliability requirements into equipment orders, crucial for operational efficiency and minimizing downtime in power stations.

Related Standards

• EN 45510 series – Other parts covering procurement of different power station equipment aligning with a holistic approach to power plant procurement.

• IEC 60034 – International standard for rotating electrical machines, often referenced for generator design and performance requirements.

• ISO 9001 – Quality management systems standards referenced for quality assurance during procurement and manufacturing.

• Relevant environmental standards – Although this guide does not cover environmental issues, related European environmental policies and standards are crucial for future compliance during generator procurement.
