Zusammenfassung:	The utility model relates to the technical field of energy storage, in particular to a phase change energy storage system. The system is used for converting electric energy in a power supply network of a hydropower station into heat energy for storage. The stored heat energy is released when the heat energy needs to be used; the system comprises an electric heating device and a phase change energystorage electric furnace, the rated power of the electric heating device is within a preset power range, the electric heating device is used for heating the phase change energy storage electric furnace through electric energy in the power supply network, and the phase change energy storage electric furnace is used for storing heat energy obtained from the electric heating device and releasing thestored heat energy when the heat energy needs to be used. The phase change energy storage system can automatically operate, is low in cost, has rated power suitable for a micro hydropower station, and can efficiently store an
