The invention discloses a fused salt energy storage power station system. The fused salt energy storage power station system comprises a cold fused salt tank, a cold fused salt pump, a steam-liquid heat exchanger, a hot fused salt tank, a hot fused salt pump, a heat exchanger set, a steam turbine generator set and a boiler; the cold fused salt tank, the cold fused salt pump, the steam-liquid heat exchanger, the hot fused salt tank, the hot fused salt pump and the heat exchanger set are connected in sequence; the boiler is connected with the steam-liquid heat exchanger, so that steam provided by the boiler heats fused salt passing through the steam-liquid heat exchanger; and after becoming into water steam through the heat exchanger set, high-pressure feed water is supplied to the steam turbine generator set for power generation. The fused salt energy storage power station system high in unit flexibility, high in frequency modulation performance, wide in unit load adjustment range, high in power generation eff
