Hydraulic turbines - Testing of control systems

Deals with the definition and the characteristics of control systems. It is not limited to the actual controller tasks but also includes other tasks which may be assigned to a control system, such as sequence control tasks, safety and provision for the actuating energy. The following systems are included, speed, power, opening, water level and flow control for all turbine types; electronic, electrical and fluid power devices; safety devices as well as start-up and shutdown devices.

Overview

IEC 60308 defines the scope and characteristics for testing control systems used on hydraulic turbines. The standard is concerned not only with core controller functions but also with ancillary tasks that may be assigned to a control system - for example, sequence control, safety interlocks and provision for actuating energy. It applies across turbine types and to a range of devices, including electronic, electrical and fluid-power equipment.

This guidance supports engineers, test laboratories, OEMs and asset owners in assessing control-system performance to secure safe, reliable and predictable turbine operation.

Key Topics

• Systems covered: speed control, power control, wicket/gate opening control, water level control and flow control for all turbine types.
• Device types: electronic controllers, electrical actuators and fluid power devices used within turbine control systems.
• Functional scope: primary controller tasks plus sequence control, start-up and shutdown functions, and safety device behaviour.
• Actuating energy: considerations for the supply and reliability of energy used to operate actuators and safety devices.
• Safety and reliability: criteria and considerations to evaluate fail-safe behaviour, response to faults and protective actions.

Practical keywords: hydraulic turbines, control systems testing, speed control, power control, water level, flow control, safety devices, actuating energy, sequence control.

Applications

IEC 60308 has practical value across multiple stages of the turbine lifecycle:

• Design and vendor evaluation: use the standard to define acceptance criteria for control-system components and integrated controllers during procurement.
• Factory and site testing: structure commissioning and functional tests for speed, power, opening and level control to demonstrate compliance with expected performance.
• Commissioning and start-up: verify sequence control and start/stop procedures, ensuring actuating energy provisioning and safety interlocks operate correctly.
• Maintenance and troubleshooting: apply standard-aligned tests to diagnose performance degradation, verify repairs and validate controller adjustments.
• Safety assurance: demonstrate that safety devices, interlocks and shutdown functions meet the operational and protective requirements for hydraulic installations.

Related Standards

• ICS classification: 27.140 Hydraulic energy engineering, which situates IEC 60308 within the broader hydraulic energy and turbine standards landscape.
• For broader programme alignment, refer to other IEC and national standards addressing hydraulic turbines, electrical drives and safety systems (consult your standards body or IEC catalogue for specific references).

IEC 60308 provides a practical framework for consistent, repeatable testing of turbine control systems, helping stakeholders achieve dependable performance, safer operation and clearer acceptance criteria when commissioning or maintaining hydraulic turbine installations.
