GB/T 11805-1999 Basic technical requirements for automation components (devices) and systems of hydro-generator sets

This standard specifies the basic technical requirements, test methods, acceptance rules, marking, packaging, etc. of the automation components (devices) and systems of turbine generator sets and water inlet valves of hydropower stations that meet one of the following conditions. A) The capacity of a single unit is 3,000 kW or above; B) When the turbine is a mixed flow or impulse type, the nominal diameter of the runner is 1.0 m or above; C) When the turbine is an axial flow, diagonal flow, or cross-flow type, the nominal diameter of the runner is 1.4 m or above. Pumped storage reversible units and turbine generator sets that are smaller than the above range can refer to this standard.
