Title:
NOVEL FREQUENCY CONVERSION SYSTEM FOR THERMAL POWER STATION
Document Type and Number:
WIPO Patent Application WO/2015/124122
Kind Code:
A1
Abstract:
A novel frequency conversion system for a thermal power station, at least comprising a steam turbine (T) having an adjustable rotation speed, a water-feed pump (P), a generator (G), a speed change gear box (GB), frequency conversion buses (a) and auxiliary machines (M1, M2, M3, Mn) connected thereto. With the change of a unit load, the amount of extraction steam entering the steam turbine and a parameter may change correspondingly, so that the rotation speed of the steam turbine changes synchronously, thereby changing the rotation speed of the water-feed pump on the one hand, and changing the frequency of an alternating current which is output by the generator on the other hand. In the novel frequency conversion system, there is no need to arrange other types of frequency converters additionally, the system is simple, the reliability is high, and the occupation of land is less.
