Beschreibung
Zusammenfassung:	The utility model discloses a thermal power heat supply unit energy storage type power grid frequency modulation and load climbing system which comprises a boiler, the first output end of the boiler is connected with a high-pressure bypass temperature and pressure reducer, a high-pressure cylinder and a steam pressure balancer, and the input end of the high-pressure cylinder is provided with a high-pressure cylinder steam inlet adjusting valve set. The output end of the high-pressure bypass temperature and pressure reducer and the output end of the high-pressure cylinder are both connected with the second input end of the boiler. The two ends of the steam pressure balancer are connected with a fresh steam and high-speed efficient fast-assembling steam turbine communication valve in parallel. According to the utility model, the steam main regulating system and the low-pressure cylinder regulating system of the unit are coupled and regulated in a heat supply period, so that the rapid frequency modulation and cl
