EVS-EN IEC 61362:2024

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 serves also 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 interaction with the electrical grid in case of primary and secondary frequency control (see also Annexes B and C) 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 impulse-type 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 and specific test procedures are outside the scope of the guide; those topics are covered by IEC 60308.
