Embodiment 1

[0039] Such as figure 1 As shown, a thermal power plant peak-shaving system is combined with cross-seasonal natural water heat storage and electrode boilers, including power plant wiring system, cross-seasonal heat storage peak-shaving system, and heat supply network system. The cross-seasonal heat storage peak-shaving The system includes a cross-seasonal natural water system, a heat storage heat source system and a heating network water pipeline connection system.

[0040] In this embodiment, the cross-seasonal natural water body system includes a water storage pit, a hot water storage body 7, a water distributor, a protective layer and a covering layer.

[0041] In this embodiment, the water storage pit is formed by civil engineering excavation, and the cross-sectional shape includes a trapezoid.

[0042] In this embodiment, the bottom of the water storage pit and the surrounding hypotenuse soil are leveled.

[0043] In this embodiment, the hot water storage body 7 include...

Embodiment 2

[0067] This embodiment is the same as the system structure of the cross-seasonal natural water heat storage and the electrode boiler combined with the peak regulation of the thermal power plant described in Embodiment 1, the difference is that one or several electrode boiler bodies are replaced by solid electric boilers. The heat storage boiler forms a liquid and solid electric heat storage hybrid system, and finally transfers the hot water heated by the two electric boilers into the natural water body for heat storage. The system includes the electrode boiler body, solid electric heat storage boiler and its connection to the power grid. The system uses a combination of electrode type hot water heat storage device and solid type electric heat storage device for deep peak regulation. The respective advantages of the boilers are that the voltage of the electrode type solid electric heat storage boiler changes smoothly and has little impact on the power grid, while the solid elect...

The system comprises a power plant wiring system, a cross-seasonal heat storage peak regulation system and a heating pipe network system; and the cross-seasonal heat storage peak regulation system comprises a cross-seasonal natural water system, a heat storage source system and a heat network water pipeline connecting system. With the thermal power heating unit operation flexibility technology and the electric boiler area heating technology, in combination with cross-seasonal natural water heat storage in summer, depth thermal power plant peak regulation in summer can be realized, so that the online peak regulation ability of a thermoelectric unit in summer can be remarkably increased, the dilemma of consumption of renewable energy sources can be effectively relieved, large-volume cross-seasonal heat storage of heating hot water can also be realized, and the system has the broad market development prospect in the future.

Description

technical field [0001] The invention relates to the field of power plant on-grid power adjustment field, in particular to the field of deep peak regulation of thermal power plant heating units in summer. Background technique [0002] In China's three northern regions, the power market has ample capacity, gas turbines, pumped storage and other peak-adjustable power sources are scarce, the contradiction between power grid peak-shaving and the flexibility of thermal power units is prominent, and the grid's ability to accommodate new energy sources such as wind power, photovoltaics, and nuclear power is insufficient , the wind abandonment phenomenon is serious. At present, with the implementation of power ancillary service transactions in Northeast China, more and more thermal power plants have realized thermal power decoupling and deep peak shaving in winter through thermal power flexibility technology. But in summer, because there is no heating service, neither the steam turb...
