CEI EN 61362

This International Standard includes relevant technical data
necessary to describe hydraulic turbine governing systems and to
define their performance. It is aimed at unifying and thus
facilitating the selection of relevant parameters in bidding
specifications and technical bids. It will also serve as a basis
for setting up technical guarantees.

The scope of this standard is restricted to the turbine
governing level. Additionally some remarks about the control loops
of the plant level and about primary and secondary frequency
control (see also Annex B) are made for better understanding
without making a claim to be complete.

Important topics covered by the guide are:

– speed, power, water level, opening and flow (discharge)
control for reaction and impulsetype turbines including double
regulated machines;

– means of providing actuating energy;

– safety devices for emergency shutdown, etc.

To facilitate the setting up of specifications, this guide also
includes data sheets, which are to be filled out by the customer
and the supplier in the various stages of the project and the
contract.

Acceptance tests, specific test procedures and guarantees are
outside the scope of the guide; those topics are covered by IEC
60308.
