Embodiment 1

[0068] A low-power wind power energy storage system is designed, which consists of a 100W wind power module 1, two 12V100Ah lead-acid maintenance-free battery packs 4 connected in series, and the energy storage control device 11.

[0069] The energy storage control device 11 includes a measurement and control device 2, a wind power input terminal 3, a power output interface 5, a wind power acquisition device 6, and a patrol device 12. The measurement and control device 2 is electrically connected to the power output terminal of the wind power component 1 through the wind power input terminal 3; The signal input terminals of the detection device 12 are respectively connected to the two ends of two storage batteries (battery modules), and the signal output terminals are connected to the measurement and control device 2; The control logic switch connects the three external terminals of the two batteries connected in series, that is, respectively connects the two ends of the batter...

Embodiment 2

[0078] Change the two 12V100Ah lead-acid maintenance-free storage batteries described in Example 1 into four 6V100Ah lead-acid maintenance-free storage batteries, and connect the four batteries in series to form the two extremes of the storage battery pack 4 and the three series taps in the middle, totaling five The external terminal; the power output interface 5 is correspondingly composed of 5 electronically controlled logic switches, and the measurement and control device 2 is respectively connected to the two extremes of the battery pack with 4 batteries connected in series and the middle 3 series tap terminals through the 5 electrically controlled logic switches. The connection method of the 5 electronically controlled logic switches and the 5 external terminals of the battery pack connected in series, and the rest of the connection methods of the wind power energy storage control equipment and the energy storage system are similar to those in Embodiment 1.

[0079] This e...

Embodiment 3

[0081] Embodiment 2 is further modified, and four 6V100Ah lead-acid maintenance-free batteries are replaced with twelve 2V100Ah single lead-acid batteries, and each single battery is connected in series externally, and the external series connection interface of the single battery is also used as a battery The external terminal of the module; the power output interface 5 is correspondingly designed to be composed of 13 electronically controlled logic switches, and the method of connecting it with the 13 external terminals of 12 single batteries is similar to that of Embodiment 2.

[0082] In this embodiment, the 13 electronically controlled logic switches of the power supply output interface 5 perform corresponding on / off combinations under the programming control of the measurement and control device 2, so that the charging intensity of the single battery can be realized indirectly when the wind energy is weaker. Improvement, to further utilize the electric energy obtained by th...

Description

technical field [0001] The invention relates to the design field of energy storage systems for wind power generation, in particular to a wind power energy storage system with energy storage control equipment and a control method thereof. Background technique [0002] The application of wind power is a hot spot in the development of new energy. Wind power components, also known as wind power generators, are a technology that directly converts wind energy into electrical energy by utilizing the change of magnetic flux of coil windings in wind energy devices; wind power generation systems in a narrow sense refer to wind power components, control Inverter and inverter are three parts, not involving battery and mechanical parts. [0003] Wind power generation system is divided into independent wind power generation system, grid-connected wind power generation system and distributed wind power generation system, among which independent wind power generation is also called off-grid...
