<p>The invention relates to a method for starting a machine group comprising a pump turbine and a motor generator. The inventive method has the following characteristics: the flow in the pressure pipe of the turbine is delayed in order to increase the pressure in said pressure pipe; the machine group is synchronised, i.e. the generator voltage and mains voltage phases are matched; and the machine group is subjected to a load in the form of the supply of electrical energy to the network or in another form (e.g., through the generator brake).</p> |
