S31, in power plant's output detection information, when needs carry out electric load when regulating, utilize turbo generator set to send electric energy aqueous medium heated, produce the high-temperature water medium;
The present invention program is measured the power consumption information of energy output He each electricity consumer of each generating set by detecting instrument, here comprise common electric power user power utilization and power plant's electricity consumption, and these electric quantity signals all deliver to control unit, by control unit these signals are carried out processed.
According to the power consumption actual conditions of electricity consumer at that time, whether decision carries out electric load is regulated, and carries out electric load when regulating when decision, sets the actual power amount of generating set, and the unnecessary electrical power storage that generating set is sent is to energy storage device.
After the electric load adjusting is carried out in decision, utilize turbo generator set to produce electric energy aqueous medium is heated, produce the high-temperature water medium.Electric energy just is converted into thermal energy storage in the high-temperature water medium like this, and electric load has obtained adjusting.
Among this step S31, can also carry out the electric load adjusting by adjusting the high-temperature water medium temperature, if the electric load amplitude of accommodation is bigger, just higher temperature can be set, if the electric load amplitude of accommodation is less, what just the temperature of high-temperature water medium can be provided with is low, with the regulatory function of flexible control electric load.
S32, high-temperature water medium transport to the aqueous medium energy-storage units after will heating are stored;
The high-temperature water medium memory that produces among the step S31 has a large amount of heat energy, if this part high-temperature water is not done insulation and handled, then Cun Chu heat energy will fade away, though regulated electric load like this, but caused waste, in fact do not solved problems of the prior art.
