<p>The invention relates to a method for preventing unacceptable charging maneuvers in hydroelectric plants. Said method makes it possible to determin e temporal progression of the level in a surge tank and to compare an existing state with a limit curve in a phase plane on the basis of an actual level (z ) and a net inflow (.DELTA.Q). Once the limit curve has been reached, the following charge increase is interrupted so that a given minimum or maximum value of the level in the surge tank cannot be exceeded.</p> |
