Title:
STEAM GENERATING POWER STATION, PROCESS FOR OPERATING THE SAME AND INTERLINKING NETWORK
Document Type and Number:
WIPO Patent Application WO/1993/010334
Kind Code:
A1
Abstract:
A steam generating power station (1) has a steam generator (6), a steam turbine (26, 28), a condenser (36), a condensate line (38), a feed water reservoir (44) and a feed water line (46). Heat exchangers (42, 44, 50) are provided in the condensate line (38) and/or in the feed water line (46) to heat the feed water. These heat exchangers (42, 44, 50) are partially heated with bleeder steam. During temporary load peaks or power deficits in the network (68), the turbine power is increased in 20 to 40 seconds by blocking bleeding of bleed steam by means of a valve (54, 60) arranged in the bleed steam line (52, 58) that can be controlled depending on the load. Temporary load peaks can thus be partially regulated. Whithin the first 30 seconds, however, until this kind of power regulation intervenes, voltage breakdowns in the network are unavoidable. To solve this problem, a plant (4) has a supraconductive, magnetic energy accumulator (64) connected in the network (68) in parallel to the generator (2). When a power deficit occurs in the network (68), at first the supraconductive energy accumulator (64) intervenes, then increasingly the heat or steam accumulator. This invention is useful in all kinds of steam generating power stations.
