This standard specifies the basic technical requirements for automatic control components (devices) of hydropower station hydroturbine-generating sets and water inlet valves, and specifies the arrangement requirements for their related system as well as specifies the corresponding contents such as test methods and acceptance regulations, marking and packaging.
This standard is applicable to the manufacture of hydropower station automatic control components (devices) products and to the system configuration and handing over acceptance of automatic control components (devices) of hydroturbine-generating sets that meet any of the following conditions.
a) The single machine capability is 10MW or more;
b) When the hydroturbine is the impulse type, the nominal diameter of runner is 1.5m or more;
c) When the hydroturbine is the mixed-flow type, the nominal diameter of runner is 2.5m or more;
d) When the hydroturbine is radial-flow, diagonal-flow and cross-flow type, the nominal diameter of runner is 3.3m or more.
The system configuration and handing over acceptance of the automatic control components (devices), below the above scope, of hydroturbine-generating sets, pumped storage reversible sets and tide generating sets may reference this standard.
