В паротурбинной электростанции 1 с парогенератором 6, паровой турбиной 26, 28, конденсатором 36, трубопроводом для конденсата 38, резервуаром питательной воды 44 и трубопроводом питательной воды 46 в трубопроводе для конденсата 38 и/или в трубопроводе питательной воды 46 предусмотрены теплообменники 42, 44, 50 для нагревания питательной воды. Эти теплообменники 42, 44, 50 частично нагреваются паром промежуточного отбора. При кратковременных нагрузочных пиках или дефицитах мощности в сети 68 путем запирания отбора пара промежуточного отбора с помощью управляемого в зависимости от нагрузки вентиля 54, 60 в трубопроводе пара промежуточного отбора 52, 58 повышают мощность турбины в течение 20 - 40 с. За счет этого могут частично компенсироваться кратковременные нагрузочные пики. Однако в течение первых 30 с, до тех пор пока не запустится этот вид регулирования мощности, неизбежными являются провалы напряжения в сети. Чтобы избежать их, изобретение предусматривает, что установка 4 со сверхпроводящим магнитным накопителем энергии 62 подключена к сети 68 параллельно к генератору 2. Таким образом, при дефиците мощности в сети 68 эффективным становится вначале сверхпроводящий накопитель энергии 62, а затем во все большей степени накопитель тепла или пара. Изобретение является применимым в паротурбинных электростанциях всех видов. 1 ил.In a steam turbine power station 1 with a steam generator 6, a steam turbine 26, 28, a condenser 36, a condensate pipe 38, a feed water tank 44 and a feed water pipe 46 in the condensate pipe 38 and / or in the feed water pipe 46, heat exchangers 42, 44 are provided, 50 for heating feedwater. These heat exchangers 42, 44, 50 are partially heated by intermediate extraction steam. When short-term load peaks or power shortages in the network 68 by locking the extraction of steam from the intermediate selection using controlled depending on the load valve 54, 60 in the pipeline steam from the intermediate selection 52, 58 increase the power of the turbine for 20-40 s. Due to this, short-term load peaks can be partially compensated. However, during the first 30 s, until this type of power control is launched, voltage dips in the network are inevitable. To avoid them, the invention provides that installation 4 with a superconducting magnetic energy storage 62 is connected to the network 68 in parallel to generator 2. Thus, when there is a shortage of power in the network 68, the superconducting energy storage 62 first becomes effective, and then the heat accumulator or a couple. The invention is applicable in steam turbine power plants of all kinds. 1 il.
