Embodiment 1

[0072] Design a low-power control device for wind power energy storage system, and use this device together with two 12V100Ah lead-acid maintenance-free batteries and 100W wind power components to form a wind power energy storage system.

[0073] The control equipment includes a measurement and control device 2, a wind power input terminal 3, a power output interface 5, a wind power collection 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 patrol device 12 The signal input terminals of the two batteries (battery modules) are respectively connected to the two ends of the two batteries (battery modules), and the signal output terminals are connected to the measurement and control device 2; Connect the three external terminals of the two batteries in series, that is, respectively connect the two ends of the battery pack 4 connecte...

Embodiment 2

[0081] 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.

[0082]In this...

Embodiment 3

[0085] Embodiment 2 is further modified, and four 6V100Ah lead-acid maintenance-free batteries are replaced by twelve 2V100Ah single lead-acid batteries. The external terminal of the battery module; the power output interface 5 is correspondingly designed to consist of 13 electronically controlled logic switches.

[0086] 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 the wind power components in the weak wind environment, and at the same time implement time-distributed and evenly distributed charging for the 12 single batteries, so as to achieve the purpose of effective battery maintenance.

Description

technical field [0001] The invention relates to the system design field of wind power generation, in particular to a control device for wind power energy storage, an energy storage system containing the device 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] The wind power generation system is divided into independent wind power generation system, grid-connected wind power generation system and distributed wind power generation system. The independent wind power generation system is also called off...
